Test stand for capacitive filling level sensors for use in inflammatory or explosion-risk areas, has adjustable holder device electronic scales and filling body with upper and lower tanks

摘要

The test stand has a measurement container with a holder device for at least 20 filling level sensors, electronic scales and a filling body with an arrangement of upper and lower tanks, float circuits, temperature sensors, dirt pans, manual taps, valves, pumps, filling connections and ventilation connections. There is also a collecting tray to catch leaks. A computer can be used for automatic control of the testing process. The accuracy and reproducibility are ensured by using dirt pans to clean the fluid, a precision holder, unrestricted height-adjustment and exact temperature control. The test stand is secured against the risk of explosion, by using a collecting tray and a leak detector to monitor for leaking fluid and using explosion-proof electronics. All the containers are covered. A ventilation unit prevents the build-up of vapors. Float circuits prevent overflow from the tanks. The magnet valves are current-free.
