12.5 Inductive Signal Transmitter
12.5.2 Application / Function
The inductive transmitter, in conjunction with products from Medenus GmbH, is used for
monitoring the position (position closed or open) of the safety shut-off valve via remote display.
A sensor queries the position of the safety shut-off valve and a signal is transmitted via remote display. If the SSV drops
into the closed position, the switching distance will be exceeded and the sensor will lose the signal. This guarantees
continuous monitoring of the SSV control devices.
