Sensor heater (for FDU91)
The FDU90 and FDU91 sensors are optional available in a version with heater. The power for this heater must
be provided by an external power supply unit. The supply voltage is connected to the brown (BN) and blue
(BU) strands of the sensor cable.
Technical data
• 24 VDC ±10 %; residual ripple < 100 mV
• 250 mA per sensor
Note!
• If the sensor heater is applied, the integrated temperature sensor can not be used. Instead, an external
temperature sensor (Pt100 or FMT131 from Hauser) must be used. The transmitter FMU90 is
available in a version with an input for the external temperature sensor. For details refer to Technical
Information TI00397F.
• The power for the sensor heater can be supplied by the power supply RNB130 from Hauser
