In order to avoid ice build-up, the sensors FDU90 and FDU91 are available in a version with integrated sensor
heater (
6). If this heater is used, an external temperature sensor has to be applied for time-of-flight
correction. The transmitter FMU90 is available in a version with an input for the external temperature sensor.
For details refer to Technical Information TI00397F.
