Barometric Pressure Sensor AB 100

Make:  Ammonit     Model: AB 100
✅ Piezoelectric barometric pressure sensor
✅ Low power consumption
✅ Operating pressure: 600 … 1100 hPa (mbar)

Measurement principle and mounting

The piezoelectric pressure sensor’s signal is electronically amplifi 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 housing with pressure compensation.
In measurement operation the sensor needs an extern supply of at least 9 VDC.
