Microsensor Corp MDM390 Differential Pressure Transmitter

Description

Microsensorcorp MDM390 differential pressure transducer is produced by putting the OEM differential pressure sensor into full-welded housing with G1/4 female for both positive and negative cavities.

The transducer could be mounted into a measuring tube through a G1/4 female pressure port or a leading tube. It is a cable connection. The transducer could be widely used in industrial process control, flow measurement, medical devices, air dynamical measuring, liquid pressure instruments or pneumatic plants, etc.

Microsensorcorp MDM390 Features

OEM differential pressure sensor;
Full solid insulation, high stability, reliability, and accuracy;
Constant current supply;
static pressure 20MPa;
G1/4 female pressure port;
Liquid, gas, and other media differential pressure measurement;
Compact size.

Notes

We suggest installing a tri-valve between the measured point and transmitter so that the measured media can be put on positive and negative cavities slowly This would help the transducer work safely and reliably;
We suggest installing a differential pressure transducer horizontally;
Please pay attention to if the transducer’s range and static pressure could be suitable for measured pressure;
Cable length: we provide standard 1.5m cable free of charge, the extra cable should be paid additionally;
Please be careful that the pressure of the positive cavity is bigger than the negative
