Pressure Sensor

Pressure sensor is one of the most widely used sensors used in instrumentation and industrial automation and after temperature is one of the important parameters in industrial pressure processes. A pressure sensor is used to measure pressure in gases and liquids. Pressure is the force applied to the surface in Pascals in SI. The pressure sensor usually acts as a transducer that produces a function of the pressure of the electrical signal. Pressure sensors are used to control and automate many equipment in industry and even in everyday life. Pressure sensors are used indirectly to measure other variables such as fluid flow, gas velocity, and water level and height. Pressure sensors are called by other names such as pressure converter, pressure transmitter, pressure transmitter, pressure transmitter, pressure indicator, pressure gauge, piezometer, manometer. A conservative estimate is that pressure sensors are built with more than 50 technologies in at least 300 companies around the world. For example, there is a set of pressure sensors designed to measure in dynamic or dynamic mode to capture high pressure velocities at high pressures, which in practical cases, for example, to measure the combustion pressure in an engine cylinder or in a gas turbine. Is used. These pressure sensors are usually made of piezoelectric materials such as quartz.

Pressure sensors can be considered in different categories, for example in terms of pressure measurement mechanism, including silicon piezoresistive model, absolute or absolute pressure sensor, relative or gauge pressure sensor, vacuum sensor, pressure difference sensor, capacitive pressure sensors and. ... named .

To choose the right pressure sensor, you should pay attention to the following:

1. How to install a pressure sensor
2. Sensor operating temperature range
3. Type and chemical properties of the fluid under pressure
4. Output type and supply of pressure sensor
5. Ability to configure or have a sensor communication protocol
