DatasheetThe IP137 model is an application- and cost-optimized level transmitter, especially suitable as an OEM component. The screw cap simplifies handling and installation. It remains mounted during operation and protects the membrane from contaminants in the medium. The ceramic sensor operates according to the piezoresistive principle and in combination with the stainless steel housing forms a robust and slim probe. Our modular design concept rovides a wide variety of products. Feel free to contact us if you need a customization that is not listed in this datasheet.
