Vulnerability level controller, drainage switch sump level meter SSR-05

TENSE SSR-05 liquid level control relay for wells, tanks, reservoirs, or wells. Centrifugal water pumps for household use and submersible pumps are usually equipped with thermoplastic hydraulic parts and cannot operate without water under "dry friction conditions," even for short periods. Water not only lubricates the friction surfaces but also acts as a coolant that absorbs and dissipates the heat generated by friction. The centrifugal pump must be protected against possible dry running or lack of water. Potentially hazardous applications of centrifugal pumps due to the risk of dry running include pumping water from wells or boreholes with low or insufficient flow rates, pumping water from tanks or storage tanks with a finite or refillable volume, and use in pressure boosting systems. A pump without intelligence and functional safety features cannot independently detect and shut down a lack of water in the suction line or well. The SSR-05 relay for level monitoring of wells, tanks, reservoirs, or water wells is a simple and reliable device for level monitoring using two or three level sensors with adjustable sensor sensitivity and LED indication of the water level in wells/reservoirs. The SSR-05 relay can also be used to control a pump to fill a tank or to signal leaks and pump shutdown. Therefore, it is preferable to protect a pump that is at risk of running dry or having no water in the suction line. The SSR-05 relay for controlling the liquid level in a well, tank, reservoir, or water well is one of the devices that can reliably eliminate the potential risk of a dry-running pump.
