Piezoresistive silicon chip employed
Perfect long term stability
MEMS Technology
Sensor diameter: 19mm
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.
