Water detector SHT 218
The water detector SHT 218 is a ready-to-use pump control that switches on when a certain water level reaches a connected water pump and after a predetermined time also switches off again. A stepless dial adjusts the overrun time of the pump from 0 to 100 seconds. An optical warning signals the water level change.
Extension sensor cable:
If required, you can extend the sensor cable up to 50 m with a cable (2 x 0.34 mm²). You have to cut through the existing sensor cable and reconnect it with terminals.
With acoustic alarm:
The same device is available as a water detector SHT 217 with audible alarm.
Use with non-conductive liquids:
For other liquids such as fuel oil, diesel, vegetable oil, lubricating oils, etc., you need the device SHT 228 with float switch.
