The ceramic sensor element is reistant to aggressive and abrasive media. A particularly large diaphragm makes this sensor insensitive to contamination. The screened cable protects the output signal (4...20 mA) from electromagnetic interference. The capacitive measuring principle enables a very accurate and long-term stable measurement, even at lowest pressures and high overload resistance. Applications: Water, Waste water, Oil / fuel, Aggressive media.
