Aggressive liquid level transmitter P143

analogfor the chemical industryCE

The model  P143  can be used as a  level  sensor or as a  screw-in  transmitter.  The  screw-on  stainless  steel cap provides the necessary  weight to prevent floating during level measurement and at the same time protects the diaphragm.  Without the  cap,  the device can be used as a  screw-in transmitter with G 1/2 in. thread, integrated seal and protection class IP68. The measuring cell operates based on the piezoresistive principle and forms,  in combination with the polypropylene housing,  a slim transmitter with high chemical resistance.  Our modular design concept provides a wide variety of products.
