Features:
Piezoresistive silicon chip employed
Perfect long term stability
MEMS Technology
Sensor diameter: 19mm
Products Overviews:
PC10D(WTD19) differential 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. PC10D(WTD19) 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.
