Introduction
Differential pressure transducer is produced by putting OEM differential pressure sensor into full-welded housing with G1/4 female for both positive and negative cavities. The transducer could be mounted into measuring tube through G1/4 female pressure port or leading tube. It is cable connection. The transducer could be widely used in industrial process control, flow measure, medical device, air dynamical measure and liquid pressure instrument or pneumatic plant, etc.
