About the MDM390 Differential Pressure Transmitter

The MDM390 Differential Pressure Transducer is produced by putting OEM differential pressure sensor into fully-welded housing with G1/4 female for both positive and negative cavities. The transducer can be mounted into measuring tubes through G1/4 female pressure port or leading tube.

This product uses cable connection. The transducer can be widely applied in industrial process control, flow measurements, medical devices, air dynamical measurements and liquid pressure instruments or pneumatic plants, etc.
