Digital Level Relay SSR-05D - TENSE
Product description
The SSR-05D relay is designed for water level control in wells, tanks, expansion tanks or pits.
It allows for automatic pumping or draining of water and is compatible with two or three level sensors.
Digital microprocessor control ensures:
-
Long sensor lifespan - current flows between sensors in pulses, not continuously.
-
Pump delay time adjustment - suitable for wells or tanks with fluctuating water levels.
-
LED indication of water level - upper, middle and lower levels, for easy visual control.
Electrodes (water level sensors) are not included.
Main functions
-
Water level control in a well, tank or expansion tank.
-
Ability to use 2 or 3 level sensors.
-
Sensor sensitivity adjustment
-
