MDM390 Pieozresistive Differential Pressure Transducer

Product catalog summary

Features

OEM differential pressure sensor with high stability, reliability, and accuracy.
Operates with a constant current supply and can handle a maximum static pressure of 20MPa.
Equipped with G1/4 female pressure ports for both positive and negative cavities.
Suitable for measuring differential pressure in liquids, gases, and other media.
Compact design for easy integration.

Introduction

The MDM390 differential pressure transducer is designed for industrial applications, including process control, flow measurement, medical devices, and pneumatic systems. It features a full-welded housing and cable connection, allowing for easy installation via G1/4 female pressure ports.

Specifications

Pressure range: 0 to 35kPa up to 3.5MPa.
Zero output: ≤2mVDC; Output signal: ≥60mVDC.
Overpressure tolerance: 2 times full scale (FS) for positive, 1 time FS or 1MPa for negative.
Static pressure: ≤20MPa with an effect of ≤0.05mV/100kPa.
Accuracy: Typical +0.25%FS, Maximum +0.5%FS.
Zero drift: <+0.05mV/°C; FS drift: <+0.01%FS/°C.
Long-term stability: +0.3%FS/year (typical), +0.5%FS/year (maximum).
Temperature range: Compensation 0°C to 50°C, Operation -30°C to 100°C, Storage -40°C to 100°C.
Response time: Positive cavity <3kHz, Negative cavity <2kHz.
Materials: Diaphragm made of Stainless steel 316L, Housing of Stainless steel 1Cr18Ni9Ti.
Protection: IP65 with an insulation resistor of 100MΩ at 100VDC.

Order Guide

The transducer is available in various pressure ranges, from 0 to 35kPa up to 0 to 3500kPa. It is recommended to install a tri-valve between the measured point and the transmitter for safe operation. Horizontal installation is suggested, and the pressure in the positive cavity should always be greater than in the negative cavity.

Connection Details

Wire color coding: Black (+IN), Yellow (-IN), White (-IN), Red (+OUT), Blue (-OUT).
Standard cable length is 1.5m, with additional lengths available at extra cost.
