300227 Pump control with float switch

Pump control SHT 227

The water detector for pump control! The SHT 227 water detector is a plug-in pump control unit that switches on a connected water pump when a certain water level is reached and switches it off again after the water and therefore the float have sunk and a preset time has elapsed. The run-on time of the pump is set from 0 to 100 seconds using an infinitely variable dial. An acoustic and visual warning signalizes the change in water level. The robust float switch is particularly suitable for dirty water, damp environments or other liquids (e.g. heating oil, diesel, vegetable oil, lubricating oil, etc.). In contrast to a sensor, a float switch is also more reliable when it comes to switching off the pump. The switching contact of the float closes from a level of approx. 4 cm and activates the input of the water detector. The reverse switching function can also be achieved by turning the float body.
