MDM390 is piezoresistive differential pressure transducer. The product uses OEM differential pressure sensor as the sensing element built-in full welded stainless steel housing. We designed this differential transducer with G1/4 pressure ports of both positive and negative cavities.
The transducer can be mounted with the measuring tube directly or through the pressure leading tube. Cable connection is provided.
