8.2.2 Active sensors DC 0 ... 10 V
The active sensors use a signal amplifier which emits a standard DC 0...10 V
signal. This voltage range is proportional to the application range of the sensor.
Active sensors are available for:
– Relative humidity
– Pressure in liquid and gaseous media
– Differential pressure in liquid and gaseous media
– Air quality
– Air velocity

When the process value is outside -1.5...11.5 V, a fault message will be sent.
For a workaround (Zener diode), see CM110563.
