• Piezoelectric barometric pressure sensor
• Low power consumption
• Operating pressure:
AB 60 (S31105) 800 ... 1100 hPa (mbar)
AB 100 (S31205) 600 ... 1100 hPa (mbar)
Measurement principle and mounting
The piezoelectric pressure sensor’s signal is electronically ampliïĴ ed to provide
an output signal of 0...5 VDC. The sensor is mounted in a stainless steel housing,
protection class IP64 when the connector is plugged in.
If required, the sensor is ready for connection in an Ammonit steel cabinet.
When mounted outside the central steel cabinet we recommend protective hous-
ing with pressure compensation.
In measurement operation the sensor needs an extern supply of at least 9 VDC.
