Description

Applications

  • Mounting on engines, tanks, vessels or enclosures, where, due to a lack of space, installation within them is not possible
  • Use for turbulent liquid levels such as in oil sumps in large engines, gearboxes etc.
  • Pump and level control and monitoring of distinct filling levels
  • Chemical, petrochemical industry, natural gas, offshore, shipbuilding, machine building, power generating equipment, power plants
  • Process water and drinking water treatment

The model RLS-3000 float switch with temperature output combines the recording of the level and temperature of liquids in a single measuring point. The stainless steel used is suitable for a multitude of media such as: oil, water, diesel, and refrigerants.

Measuring principle

A permanent magnet built into the float triggers features potential-free reed contacts built into the guide tube. The triggering of the reed contacts by the permanent magnet is contact-free and thus free from wear.

Depending on customer wishes, the switching functions of normally open, normally closed or change-over can be realised for the defined liquid level.

The additional temperature output enables the medium temperature to be monitored by means of a preconfigured bimetal temperature switch or a Pt100/Pt1000 resistance signal.
