Level pilot NP632

NP 632 consists partly of a floating body with a shock-safe fixed micro-switch with switching contact function, and a freely suspended weight-loaded cable. The pilot body, cable, and weight are surrounded by a sheath of vulcanized Hypalon. The weight that is attached as vulcanized on the cable is to keep the float body submerged, then the liquid level rises up to and above the pilot. In this respect the weight functions as a sinker around which the floating body can oscillate. In the pump control the smallest connection difference is 130 mm with which only one pilot is required. For greater connection differences two pilots are required, one for the switching on and one for switching off. If several pumps are used, a single pilot can be mounted for switching off.
