Digital level relay SSR-05D – TENSE
Product description
Relay SSR-05D is designed for water level regulation in wells, tanks, expansion tanks, or pits.
Enables automatic water pumping or draining and is compatible with two or three level sensors.
Digital microprocessor control ensures:
-
Long sensor lifespan – current between sensors flows intermittently, not continuously.
-
Pump delay time adjustment – suitable for wells or tanks with variable water levels.
-
LED water level indication – upper, middle, and lower levels for easy visual monitoring.
Electrodes (water level sensors) are not included in the package.
