Functional description:
The water detector SHT 227 is a plug-in pump control which switches on a connected water pump when a certain water level is reached and also switches it off again after the water, and thus the float, has sunk and a preset time has elapsed. An infinitely variable dial is used to set the pump's run-on time from 0 to 100 seconds. An acoustic and optical warning signals the water level change. 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 addition, a float switch, in contrast to a sensor, stands for higher reliability in the shutdown behavior of the pump. The switch contact of the float closes from a level of approx. 4 cm and activates the input of the water detector. By turning the float body around, the reverse switching function is also obtained.
Without audible alarm:
The same device is available as water detector SHT 228 without acoustic alarm.
Extension Sensor cable:
If required, you can extend the sensor cable up to 50 m with a cable (2 x 0.14 mm²). In doing so, you must cut the existing sensor cable and reconnect it with clamps.
Order mounting bracket for float switch as well!
