Optical filling level monitor for explosive areas
The intrinsically safe optical filling level switches UFGSa Ex are ideal for the detection of fluids with low dielectric constant ("DC-value"), such as lubrication oil, hydrocarbons or solvents. Optical filling level sensors detect the change of the refractive index during medium contact at the sensor tip. The sensors with stainless steel housing and glass tip are also suited for the detection of aggressive media, such as solvents. the sensors are available with Ex certification according to ATEX and IECEx.
