DESCRIPTION
The MAXIMAT LWC-B leakage sensor (on floor detection) is used for leakage detection in catch basins and catch spaces.
It is equipped with three different output circuits:
• A binary output for controlling a coupling relay or the digital input at a PLC
• A 0 to 20 mA current output for controlling an analog input channel, e.g. a programmed logic controller (PLC)
• Self-monitoring measuring circuit in combination with the MAXIMAT SHR C... measuring transducer with a 2 wires connection.
