Leakage Detectors, Ventilators, Pressure Equalizing Vessels & Level Sensors

The level sensor detects the level of liquids based on the hydrostatic pressure that acts on the membrane of the pressure measuring cell of the level probe.

The measuring cell is made of stainless steel, the housing is made of POM, the hose screw connection is made of anodized aluminum, the cable protection hose is made of PUR, so it can also be used in areas where chemical resistance is important (in this case, heating oil EL).

The measuring amplifier is trimmed to a maximum detection pressure of 100 mbar (max. 400 mbar on request) in order to maintain compatibility with the previous model “NIVOCUP ELBD”.
In the event of an exchange, the cable colors are binding, white for the supply voltage, brown for the return signal. The output signal can also be loaded indefinitely.
