Analog monitoring relay Fill level monitoring Resistance monitoring from 2 to 200 kOhm over- and under-range Supply voltage AC/DC 24 V DC and AC 50 to 60 Hz without galvanic isolation from the measuring circuit 2 point or 1 point control Trigger delay 0.5 to 10 s 1 changeover contact Spring-loaded technology Analog adjustable fill level monitoring relay SIRIUS 3UG4 for monitoring the fill level of conductive liquids to protect against overflow, dry running or leakage. Worldwide use thanks to wide voltage supply and internationally validated. Device can be changed without rewiring thanks to removable terminals. Can be flexibly adapted to different conductive liquids thanks to analog setting of the sensitivity. Inflow or outflow function can be selected. The adjustable trigger delay time can also compensate for wave movements. Other resistance sensors can also be connected, e.g. B. suitable photoresistors, temperature sensors, resistance-based position sensors, etc.In addition to screw connection technology, the devices are also available with a spring-loaded connection for a quick, maintenance-free and vibration-proof connection.Accessories include individually shortenable 2- and 3-pole wire electrodes for easy installation from above/below, as well as bracket electrodes for installation from the side for larger filling heights and minimal space requirements. Other accessories, such as device identification plates, push-in tabs and cover caps, are standardized for all relays.SIRIUS relays - a program for all occasions.
