Capacitive level sensor P133 PP

for wastewaterfor corrosive liquidsfor aggressive liquids

The  plastic  version of the  P133  pressure  transmitter is particularly suitable for media that lead to corrosion of  stainless  steel and thus  to  sensor failure.  Due to the material of the O-ring,  e.g. FFKM (Chemraz / Kalrez),  the sensor is resistant to most aggressive chemicals.  The ceramic sensor is resistant to aggressive and abrasive media. The capacitive measuring principle enables a very accurate and long-term stable measurement, even at lowest pressures and high overload resistance.  Our modular design concept provides a wide variety of products.  Feel free to contact us if you need a customization that is not listed in this data sheet.
