Filling level controller, discharge switch Well level indicator SSR-05

TENSE SSR-05 liquid level control relay for wells, cisterns, tanks, or pits. Domestic surface and submersible centrifugal pumps are generally equipped with thermoplastic hydraulic components and cannot operate without water under 'dry friction' conditions, even for short periods of time. Water not only lubricates friction surfaces but also acts as a coolant, absorbing and dissipating the heat generated by friction. The centrifugal pump must be protected from possible dry running or lack of water. Potentially dangerous applications of centrifugal pumps due to the risk of dry running include pumping water from wells or boreholes with low or insufficient flow, pumping water from cisterns or storage tanks with finite or refillable volume, and operation in pressurization systems. A pump without intelligence and protection functions cannot independently detect the lack of water in the suction line or well and shut off. The SSR-05 well, cistern, tank, or liquid level monitoring relay is a simple and reliable device for monitoring well levels that uses two or three level sensors with adjustable sensor sensitivity and LED indication of the well/tank water level. 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 risks running dry or exhausting the water in the suction line. The SSR-05 relay for liquid level control in a well, cistern, tank, or pit is one of the devices capable of reliably eliminating the potential risk of a dry pump.
