(Summary description)Pressure sensors are devices or apparatuses that can sense pressure signals and convert them into usable output electrical signals according to specific rules. They are very common in life and are widely used in various industrial automatic control environments involving water conservancy and hydropower, railroad transportation, intelligent construction, production automation, aerospace, military, petrochemical, oil well, electric power, ship, machine tool, pipeline and many other industries.

About pressure sensors, we need to understand some of the following knowledge: working principle, usage, structure, function, correct installation method, specific installation location, unavoidable errors, anti-interference measures and four common faults.
What should we pay attention to when using pressure sensors? Next, it will be explained by the editor:
1. preventing the transmitter from contacting corrosive or overheated media;
2. preventing deposits from being deposited in the conduit;
3. when measuring liquid pressure, the pressure port should be opened on the side of the process piping to avoid the accumulation of deposits and slag.
4. when measuring gas pressure, the pressure inlet should be opened at the top of the process piping and the transmitter should be installed at the top of the process piping so that the accumulated liquid can be easily injected into the process piping.
5. the pressure conduit should be installed in a place where temperature fluctuations are small;
6. When measuring steam or other high temperature media, a condenser must be connected, such as a buffer tube (coil), and the working temperature of the transmitter should not exceed the limit.
7. winter icing, the transmitter must be installed outdoors according to take anti-freeze measures to avoid damage to the sensor due to the volume of icing caused by the expansion of the liquid inside the induction pressure port.
8. pressure sensor to measure the liquid pressure, the installation position of the transmitter should avoid the impact of liquid (water hammer phenomenon) to avoid damage to the sensor due to overpressure.
9. When wiring, run the cable through a waterproof connector (accessory) or winding tube and tighten the sealing nut to prevent rainwater from leaking into the transmitter housing through the cable.
