FLSE200 sender/receiver unit
The sender/receiver unit consists of the electronics unit and the ultrasonic transducer. The
electronics unit contains all the necessary assemblies for signal processing, digitalization
and communication. The ultrasonic transducer is firmly connected to the enclosure.
The sender/receiver unit is supplied with 24 V. Communication to the MCU is via a bus-
capable serial connection.
The sender/receiver units are available in three versions:
The protective tube of the FLSE200-M serves to protect the ultrasonic transducer from
excessive contamination and mechanical damage (e.g. during tunnel cleaning).
