The Siemens SIRIUS 3UG4 series is an analogue monitoring relay for resistance monitoring from 2 to 200 kohm used for level monitoring of conductive fluids to protect against overflow, dry running or leakage. The type of electrical connection is through spring-loaded terminals. By means of the adjustable tripping delay time, it is also possible to compensate for shaft movements. Other resistance sensors can also be connected, e.g. suitable photo resistors, temperature sensors, position encoders based on resistors etc.

Device replacement possible without rewiring due to removable terminals
Can be flexibly adapted to various conductive liquids through analogue setting of the sensitivity
