The P135K level transmitter is due to the slim and also shortened design with a diameter of 22 mm, optimal to install in 1" pipes. Typical applications are in the field of industrial and drinking water, however the sensor is also widely used in pumping and lifting systems. The ceramic sensor element is resistant to aggressive and abrasive media. Its housing is made of high-quality stainless steel 1.4404 and is therefore suitable for almost all media. 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. The P135K immersion probe has an RS485 interface.
