Installation Notes for Piezoresistive Pressure Sensor

November 11, 2020

Many people would like to know how to install a piezoresistive pressure sensor.Actually, its installation method is like other general pressure sensors, but some aspects are to be noted in actual application:

Installation Notes for Piezoresistive Pressure Sensor

                                                               piezoresistive pressure sensors are used for pressure measurement

There are seven aspects to note to install a piezoresistive pressure sensor:

The pressure guiding tube should be installed in a place with small temperature fluctuations;

When measuring steam or other high-temperature media, a condenser such as a buffer tube (coil) should be connected, and the working temperature of the transmitter should not exceed the limit.

When measuring liquid pressure, the pressure tappings should be on the side of the process pipeline to avoid precipitation and accumulation.

When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed on the upper part of the process pipeline so that the accumulated liquid can be easily injected into the process pipeline. Prevent the sensor from contacting corrosive or overheated media; Prevent dross from depositing in the duct; When freezing occurs in winter, anti-freezing measures must be taken.

With correct installation of piezoresistive pressure sensors, their service time will be much extended while with improper installation, the stability and life time would be affected. While for some specific applications, it is recommended to follow the user manual or consult with the manufacturer.
