Sensors provide improved tracking ability and maintain calibration over long periods of time. When replacing a sensor, you do not need to recalibrate.
These sensors are suited for use with mercury and oil pumps.

Pirani type sensors offer enhanced stability and an automatic temperature compensation network. The 304 stainless steel sensors operate at half the
temperature of standard thermopile sensors. Use for high-vacuum applications.

Diaphragm type sensor offers quick response—less than 400 milliseconds full-scale. Select a diaphragm type sensor made from 316 stainless steel or silicon based on your application.
