Function of pressure sensor

Pressure Transmitter is a commonly used sensor in industrial practice. The development of pressure transmitter has made a great breakthrough in technology. The transmitter is an important part of the automatic control system. The pressure transmitter is mainly used for the measurement and control of pressure parameters in industrial processes.

It is widely used in petroleum, chemical industry, electric power and other fields. There are many kinds of pressure transmitters, which are classified in different ways according to different working principles and purposes. The pressure transmitter is mainly used for remote display and control of pressure. It often works under high temperature, low pressure, corrosion, vibration and other environments, and has a high probability of failure. Therefore, it is very meaningful to study the influencing factors and common failures of the pressure transmitter.

The module circuit, display meter, load cell sensor, meter case, etc. constitute the pressure transmitter. The pressure difference from the impulse pipes on both sides will act on the diaphragms on both sides of the transmitter sensor. The measuring element can convert the received pressure signal into a standard current and voltage signal, and send the signal to the alarm, recorder and regulator for secondary measurement.

At present, the Pressure Sensor is widely used. Whether it is a domestic transmitter or an imported transmitter, various failures will occur due to the working environment, improper human operation or their own reasons during the use process. Therefore, not only should you operate according to the standard specifications in the instructions, but also you should master the correct fault judgment, maintenance and repair knowledge, so as to ensure the service life and measurement accuracy of the pressure sensor.
