Jola – NVM/PP Level Controllers


Jola – NVM/PP Level Controllers

These level controllers are fitted with a float, a float rod, a guide tube made of transparent PVC and a magnet.

The float follows the level of the liquid and moves the float rod of the unit up or down. Above the nipple the guide tube is attached for the float rod and the magnet. Adjustable HMW/./32 magnetic switches are mounted on the outside of the tube.

These magnetic switches have a so-called bistable characteristic; i.e. they remain in the switching status caused by the influence of the passing magnet and only switch over when the magnet passes by in the opposite direction.
