Product DescriptionFeatures:Piezoresistive silicon chip
employedPerfect long term stabilityMEMS TechnologySensor diameter:
19mmProducts 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 rangeThe 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. Product Parameters Pressure
