Technical Description

4.1

The Hybrid Cable

The hybrid cable is constructed for very harsh environments and consists of two optical
fibers, one for transmission of the laser light to the measurement volume (single-mode fiber)
and one for the return of the detected signal (multi-mode fiber). Two twisted electrical wires
are used for powering the electronics in the sensor (24 VDC).

The Loop Cable

The loop cable connects the transmitter sensor to the receiver sensor. This cable is a hybrid
cable that does not contain the single-mode fiber.
