Definition of force measurement sensor

The national standard GB7665-87 force sensor is defined as: "a device or device that can feel the specified measured and convert it into a usable signal according to certain laws, usually consisting of a sensitive element and a conversion element". Force sensor is a detection device, can feel the measured information, and can detect the felt information, according to certain laws into electrical signals or other required forms of information output, to meet the requirements of information transmission, processing, storage, display, recording and control. It is the primary link to achieve automatic detection and automatic control.

The role of force measurement sensors

In order to obtain information from the outside world, people must use their sensory organs. And people's own sense organs alone, in the study of natural phenomena and laws and production activities in their function is far from enough. In order to adapt to this situation, force sensors are needed. Therefore, it can be said that force sensors are an extension of the five human senses, also known as the five electrical senses. With the advent of the new technological revolution, the world began to enter the information age. In the process of using information, the first thing to solve is to obtain accurate and reliable information, and force measurement sensors are the main way and means to obtain information in the field of nature and production. In modern industrial production, especially in the automated production process, a variety of force sensors are used to monitor and control the various parameters of the production process, so that the equipment works in a normal or optimal state, and the product achieves the best quality. Therefore, it can be said that without numerous excellent force sensors, modern production would lose its foundation.

In the basic disciplines of research, force measurement sensors have a more prominent position. The development of modern science and technology, into many new areas: for example, in the macroscopic to observe thousands of light years of the vast universe, microscopic to observe the world of particles as small as nm, vertical to observe the evolution of celestial bodies up to hundreds of thousands of years, as short as s instantaneous reaction. In addition, there are also various extreme technology researches that play an important role in deepening material understanding and developing new energy and materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, ultra-weak magnetic stone, etc. Obviously, to obtain a large amount of information that is not directly accessible to human senses, it is impossible to do so without a compatible force measuring sensor. Many obstacles to basic scientific research lie first in the difficulty of obtaining object information, and the emergence of some new mechanisms and high-sensitivity detection force sensors often leads to breakthroughs within the field. The development of some force measurement sensors is often a precursor to the development of some marginal disciplines.

Force sensors have long penetrated into a wide range of fields such as industrial production, cosmic development, ocean exploration, environmental protection, resource investigation, medical diagnosis, biological engineering, and even heritage conservation. It is no exaggeration to say that from the vast space, to the vast ocean, to a variety of complex engineering systems, almost every modern project, are inseparable from a variety of force sensors.

It can be seen that the force sensor technology in the development of economic and social progress of the important role, is very obvious. Countries all over the world attach great importance to the development of this field. It is believed that in the near future, force sensor technology will take a leap and reach a new level commensurate with its important status.

What are the materials of the force sensor?
   A force sensor consists of three parts: a bridging circuit made up of one or more elastomers (such as a Wheatstone bridge), elastomers that deform when subjected to stress, a resistance strain gauge that senses the deformation, an adhesive that holds the resistance strain gauge to the elastomer and conducts the strain, and a sealant that protects the electronic circuit. When the force sensor is subjected to an external force, the strain gauge attached to the elastomer will deform and cause a change in resistance. The change in resistance causes the Wheatstone bridge to lose balance and outputs an electrical signal that is linearly proportional to the external force. Next, let's introduce its materials: 1, elastomer material The elastomer material of the force sensor is usually made of metal, most of the available materials are aluminum alloy, alloy steel and stainless steel. The alloy material is not only rigid to ensure consistent deformation and deformation recovery, but also has good weather resistance and corrosion resistance. The main requirements of elastomers are to accurately transmit force information, maintain deformation consistency, and complete the reset under the same force. 2, strain gauge and resistance element materials The composition of the resistance strain gauge is complex and it is a composite manufacturing product. The combination of substrate and strain copper for strain gauges is constantly changing, with about 1,000 products available today. Generally, the substrate is a polymer film material, and the strain material is high purity constantan. The resistance grid lines with different induced deformation were optically treated and Constantan was etched on the substrate. Therefore, the quality of the resistance strain gauge is not only related to the metal purity of the matrix material and composite material, but also related to the composite process, etching process and technology, etching chemical materials and post-treatment process and material. 3, the material of the patch adhesive Two-component polymer epoxy series adhesives are mainly used for the installation of resistance strain gauges. The properties of polymer chemical products are closely related to physical and chemical indexes such as purity, molecular chain structure and size, storage time, component ratio, molecular modification, mixing method, mixing curing time, curing time, curing temperature, additives and percentage of each component. 4, sealant material Special silicone rubber sealant series are used in the initial phase of force sensors with insufficient welding processes and equipment. Silicone rubber has long-term chemical stability. Therefore, it has excellent anti-corrosion, moisture, aging resistance, insulation and other properties. It has long been the product of choice for all sealants. 5, load cell wire material The wire is still part of the force sensor. Personal experience of metal materials of force sensor wires with quality differences due to the use of household appliance wires. After all, the wire is the channel for bridge power supply, signal output and long line excitation voltage compensation. Silver-plated wire is definitely better than copper wire, and copper wire is definitely better than aluminum wire. Its role is self-evident. With the increase of various high frequency and radio wave interference, good shielding of force sensors is also an important method to protect signal stability. In addition, environmental corrosion, pest and mouse invasion, fire and flame retardant also require the sensor protective layer material to prevent corrosion, insect infestation, fire and explosion, and even need armor protection, shell protection and other methods.

What is a force sensor? What are the types?
  Force is the direct cause of changes in material motion, and force sensors can detect mechanical quantities such as tension, tension, pressure, weight, torque, internal stress and strain. The force sensor is usually composed of a sensitive element and a conversion element, which is a device or equipment that can sense the specified measurement data and convert it into usable signals according to certain rules. Force sensors have been widely used in this new era, and are now widely used in the industrial field. In order to use the force sensor well, it is necessary to have a certain understanding of the definition and function of the force sensor. So, what is a force sensor? What are the types? Let's take a look! There are many kinds of force sensors, which can be divided into resistance strain sensors, piezomagnetic sensors and piezoelectric sensors according to different physical effects and detection principles. 1, strain type force sensor. Strain gauge force sensors are widely used in all force sensors. It has high measurement accuracy and can measure dynamic and static forces from small to large, and its usage accounts for about 90% of the total sensor. The working principle of the strain gauge force sensor is basically the same as that of the strain gauge pressure sensor, which is also composed of an elastic sensitive element and a strain gauge attached to it. The strain gauge force sensor first converts the measured force into the strain of the elastic element, and then reads the output by measuring the strain using the resistance strain effect. 2, voltage power sensor. When a ferromagnetic material is strained and pressed by an external force, its permeability will change with the magnitude and direction of the stress. When the tension acts, the permeability increases along the direction of the force, but decreases slightly in the direction of the vertical force, and the change of the permeability under pressure is just the opposite. This physical phenomenon is the piezomagnetic effect of ferromagnetic materials, which can be used for force measurement. 3. Piezoelectric sensor. Piezoelectric sensors can measure various dynamic forces, mechanical shock and vibration, and are widely used in the fields of acoustics, medicine, mechanics and navigation, with small size, light weight, high frequency response and high signal-to-noise ratio. According to the shape, the load cell can be divided into cantilever load cell, S-shaped load cell, plate load cell, box type load cell and spoke type load cell. Force sensors have penetrated into a wide range of fields, such as resource survey, ocean exploration, space development, industrial production, environmental protection, medical diagnosis, bioengineering, and even cultural relics protection. Force sensors have long penetrated into a wide range of fields, such as resource survey, ocean exploration, space development, industrial production, environmental protection, medical diagnosis, bioengineering, and even cultural relics protection.

Analysis of characteristics and working principle of torque sensor
    The emergence of the torque sensor itself should be used in all walks of life in a short time and become an indispensable variety in the sensor series. First, the characteristics of torque sensor: 1, can measure both static torque, can also measure rotary torque, can measure both static torque, can also measure dynamic torque. 2, high detection accuracy, good stability; Prevent interference; 3, small size, light weight, diverse installation structure, easy to install and use. Continuous measurement of positive and negative torques without repeating 0. 4, no conductive ring and other wear parts, can be high-speed long time running. 5, the sensor output high level frequency signal can be directly sent to the computer for processing. 6, measuring the strength of the elastomer can withstand high overload. Second, the torque sensor measurement principle: The special torsion strain gauge is attached to the measured elastic shaft as a strain glue to form a strain bridge and supply power to the strain bridge. The electrical signal of torsion of the elastic shaft can be measured. After amplifying this deformation signal, it undergoes pressure/frequency conversion and becomes a frequency signal proportional to the torsion reaction. The energy input and signal output of the system are handled by two sets of special annular transformers with a gap, thus providing contactless energy and signal transmission. Third, the torque sensor principle structure: The basic torque sensor-variable bridge is formed by attaching a special torsion measuring sheet to a special elastic shaft. Fixed on the shaft: (1) the secondary coil of the energy ring transformer, (2) the primary coil of the signal ring transformer, (3) the axis printed circuit, and the circuit board including the rectifier stable power supply, the instrument amplifier circuit, the V/F conversion circuit and the signal output circuit. 4. Working process of torque sensor: The sensor is supplied with a 15V power supply, a crystal oscillator on the magnetic circuit generates a 400Hz square wave, and an AC magnetoelectric power supply is generated through the TDA2030 power amplifier. The energy loop transformer T1 is transferred from the stationary primary coil to the rotating secondary coil. Results The AC power supply obtained 5V DC power supply through the rectifier filter circuit on the shaft. The power supply is used as a working power supply for the operational amplifier AD822. A high precision power supply consisting of a reference power supply AD589 and a dual operational discharge AD822 generates a 4.5V DC power supply. The power supply is used as a working power supply for bridging power supplies, amplifiers, and V/F converters. When the elastic shaft is twisted, the MV-class deformation signal detected on the deformation bridge is amplified by the instrument amplifier AD620 to a strong signal of 1.5v 1v, and then converted into a frequency signal by the V/F converter LM131. Through the signal ring transformer T2, it is possible to pass from the rotating primary coil to the stationary secondary coil, and then through the signal processing circuit filter of the sensor housing, shaping, obtaining a frequency signal proportional to the torque received by the elastic bearing, because the rotating transformer is in motion, zero between the static rings. With a gap of only a few millimeters, part of the sensor shaft is sealed inside the metal housing, forming an effective shield, and therefore has a strong anti-interference ability.

What are the advantages and disadvantages of torque sensors?
    The large-scale use of a thing has its advantages and disadvantages, such as torque sensors have advantages and disadvantages in the development process. Torque sensor, also known as torque sensor, torque sensor, torque sensor, torque meter, divided into dynamic and static two categories, of which dynamic torque sensor can also be called torque sensor, non-contact torque sensor. The following is a brief introduction to the advantages and disadvantages of torque sensors. First, the advantages of torque sensor With the continuous improvement and development of automatic control system, the reliability and response speed of torque sensor are put forward higher requirements. Torque sensors show the following trends. 1. The test system is developing in the direction of miniaturization, digitalization, intelligence, virtualization and networking. 2, from single function to multi-function development, including self-compensation, self-correction, adaptation, self-diagnosis, remote setting, state combination, information storage and memory; 3. Develop in the direction of miniaturization and integration. The detection part of the sensor can be miniaturized through rational design and optimization of the structure, and the IC part can integrate as many semiconductor components and resistors as possible into a single IC part, thus reducing the number of external parts. 4, static test to dynamic online detection direction; Second, the shortcomings of the torque sensor The success of the telemetry torque meter lies in overcoming two defects of the electric slip ring. But there are three drawbacks. One is vulnerable to the use of field electromagnetic waves. The second is because it is a battery power supply, so it can only be used in the short term. Third, the structure is attached to the rotating axis, which is easy to cause the dynamic balance problem of high speed, so it is more prominent on the small distance and small diameter axis. The digital torque sensor absorbs the advantages of the above methods and overcomes the defects. Based on the deformation sensor, two sets of rotary transformers are designed to realize the non-contact transmission of energy and signal. The transmission of the torque signal has nothing to do with rotation or not, nothing to do with the speed, and nothing to do with the direction of rotation. Three, the main characteristics of the torque sensor are as follows: Dynamic and static torque can be measured. The stability of the check is very good, the anti-interference performance is very strong, and the accuracy is very good. It does not need to adjust 0 each time when measuring, and can continuously measure the positive and negative torque. Its signal output can be manipulated by you, with a choice of pulse wave or waveform - square wave. Wide measuring range. There are 0 to 1000Nm standards to choose from, and some non-standard ones such as 20,00 NM, 100,000 NM, 100,000 NM, etc., can be customized using a special range of customization. The volume is very small, the heavy sensor can be used independently from the secondary instrument, and only the 15V and -15V power supply provided by the socket pin number can output the pulse wave or equal square wave frequency signal proportional to the impedance and the forward relationship, which is very light and convenient to install.
