The water detector SHT 228 is a ready to plug pump control system which, when it reaches a certain water level a connected water pump on and after a specified time also switches off. Via a continuously variable adjustment wheel is the follow-up time of the pump from 0 to 100 seconds. An audible and visual warning signals the change of the water level.The robust float switch is particularly suitable for dirty water or other liquids (e.g. fuel oil, diesel, vegetable oil, lubricating oil, etc.). The switching contact of the float closes from approx. 4 cm level high and activates the input of the water sensor. By turning the float body, one gets the reverse switching function.Extension sensor cable:If required, you can change the sensor cable up to 50 m with a cable (2 x 0.5 mm²) extend. You must re-connect the existing sensor cable cut and terminals.This text is machine translated.
