Piezoresistive silicon chip employed Perfect long term stability
MEMS technology
CE certificate
Sensor diameter: 19mm
Industrial pressure sensor is a standard and most popular sensor applied in air and liquid pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. The housing is filled with oil for pressure transmission. The most important specification for industry application is long term stability. The sensor is designed for industry application with perfect long term stability.
Diaphragm and pressure range
The diaphragm diameter has tight relation with pressure measured. Low pressure requires large diameter and high pressure needs small diameter. This is caused by oil expansion during temperature changing. It creates internal pressure due to the resistance of the diaphragm. The smaller diaphragm will create large internal pressure, and it is difficult to make zero compensation.
Caution
1. Please do not touch the diaphragm by finger and other hard objects, or it may be damaged
2. The sensor will not work, if the excitation and output are reversed connected due to polarity protection.
