Fill level sensors

Filling level monitor with optical measuring principle

The optical filling level switches of this series are ideal for the detection of fluids with low DK value, such as lubrication oil or hydrocarbons. Optical filling level sensors detect the change of the refractive index at medium contact with the transparent tip from polyethersulphone (PES) or glass. The sensors with stainless steel housing and glass tip are also suited for the detection of aggressive media, such as solvents. Also available with Ex certification according to ATEX and IECEx.

UFGS

Optical filling level monitor with resistant glass tip for the reliable monitoring of the maximum or minimum filling level of fluids
Detects fluids with a very low DK values, such as oil
Resistant to detergents, hydraulic and lubrication oil
Resistant materials: stainless steel and glass
The medium changes the refractive index at the sensor tip and thus triggers a switching signal upon touching
