Product Overviews

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.

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
Please do not touch the diaphragm by finger and other hard objects, or
it may be damaged.
