Digital water level relay SSR-05D - TENSE
Product description
The relay SSR-05D is designed for water level control in wells, tanks, expansion tanks, or pits.
It enables automatic pumping or draining of water and is compatible with two or three level sensors.
Digital microprocessor control offers:
-
Long sensor lifespan - current does not flow continuously between the sensors, but in pulses.
-
Pump delay time setting - suitable for wells or tanks with variable water levels.
-
LED indication of the water level - upper, middle, and lower level, for easy visual monitoring.
Electrodes (water level sensors) not included.
