Level Controller Weight and

A special plastic-coated weight for stabilisation and fixation of the switch-on and switch-off points of the KR 1 level controller. The weight is fixed to the cable so that it cannot slip. The cable length between the weight and the controller determines the difference between

the switch-on and switch-off points The adapter plug is used for the retrospective or occasional conversion of a water drainage pump from manual to automatic operation.

Application

Thanks to the good chemical and thermal properties of the absolutely waterproof polypropylene housng, as well as the high-quality and extemely flexible PUR / PVC special cable, the level controllers are resstant to suds, waste water, oils, petrol, diesel oil, alcohols etc., and also to many chemicals For the transport of less critical media, such as normally-soiled household waste water, ground and rain water, etc., level controllers with HO7RN-F neoprene cables can be used. We will be happy to advise you in case of doubt.

Installation and Maintenance

When installing the level controller, it is essential to ensure that it can hang freely in the vertical position, does not lie against the bottom, can freely float without being impeded by the walls of the shaft, pipelines, fittings, etc., and does not lie directly in the current.

Cable fittings with pressure relief clamps must be used for fixation. With the correct installation and fixation, the level controller will work practically without need for maintenance. Depending on the level of soiling of the medium, it is only necessary to check the system for deposits from time to time, and to clean it where necessary.
