Ex level controller for explosive fluids
In potentially explosion hazardous areas (zone 0), the fill level of gasoline and similar explosive fluids is easily and reliably monitored with the Ex sensor UFGS 075 Ex…. This sensor is resistant to common fuels and oil, acidic, and alkaline solution admixes as well as other aggressive fluids. The sensor reacts upon contact with the fluid and does not have to be adjusted to the fluid.
The sensor is available in different lengths; non-standard lengths are manufactured in accordance with customer specifications. The material is stainless steel AISI 316 Ti combined with glass and a Kalrez (FFKM) seal. The device is constructed with an "intrinsically safe" type of protection and connects to a separate amplifier type EGE 903-Ex....
Optical sensors react to a change of the refraction index within the proximity of the sensor tip when being immersed into fluid. The sensor does not have to be adjusted. In rare cases, the container wall or particles within the fluid may reflect the light emitted by the sensor and thus interfere with the fluid detection. A trial run is recommended in such instances. The sensors are designed to be used with the respectively listed fluids under normal conditions. The chemical compatibility and technical suitability of the sensor should be tested when used with unlisted fluids.
