The WITT WB-CM3 monitors the insulation between the shield or conductor and an earthing point and signals the event via potential-free signaling contacts. Measurement data can also be transferred to third-party systems.

The WITT TVM system monitors the traction voltage in both directions of travel using a single, factory-preconfigured unit – ideal for installation in underground railway tunnels. Up to two TVM components – analogue voltage monitors or voltage signalling relays – are housed in a highly compact V2A stainless steel enclosure, which can withstand even severe external impacts such as rockfall or vandalism. Highly insulating separation zones within the enclosure prevent voltage cross-contamination between the different voltage ranges, as well as between the operating and signalling voltages. The system is supplied ready for operation and fully configured – there is no need for on-site commissioning or parameterisation.

The fully analog CM200 is used to detect changes between two potentials. A typical application is monitoring shields for insulation faults or interruptions.
The operating status is indicated by LEDs or potential-free signal contacts. The CM 200 operates without auxiliary power.
