Description

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. Feel free to contact us if you need a customization that is not listed in this datasheet.
