Más información del producto

The floater switches the reed contact mounted in the guide tube when the liquid level rises. The change in resistance in the sensor circuit resulting from the switching operation is evaluated and the output relay triggered.
Parts of the level sensor which get into contact with the media are completely made of PE, PP, PVC, PVDF. So the level sensors T-20_.F... are perfectly suited for being used with tanks for storing highly aggressive media.

The overfill cut-out device consists of the level sensor and the measuring transducer. Our “contact protective relays” type KR-163... and KR-268..., which are also approved by the DIBt, can be used as corresponding measuring transducers (see section 10). The level sensors T-20_.F... can be connected to our “alarm indicators” type OAA-100 and OAA-300.

Easy to install
Sturdy design
Small dimensions
Interference-proof measurement
Switching point adjustable
Various options for connection (connector box / plug / cable)
For usage in category 2 (Ex zone 1) (in combination with [Ex]i contact protective relay KR-163/A/Ex)
Short-line fault / open circuit monitoring (in combination with contact protective relay KR-163... and KR-268... / alarm indicator OAA-100...)
Under the F-contact further optional switching points can be realized
Under the F-contact its also possible to integrate a continuous measurement
