Overpressure tolerance: 2 times FS for positive, 1 time FS or 1MPa for negative.
Static pressure: ≤20MPa with an effect of ≤0.05mV/100kPa.
Accuracy: ±0.25%FS (typical), ±0.5%FS (maximum).
Temperature compensation: 0℃ to 50℃; Operating temperature: -10℃ to 70℃; Storage temperature: -20℃ to 85℃.
Response time: Positive cavity <3kHz, Negative cavity <2kHz.
Materials: Stainless steel 316L diaphragm, Stainless steel 1Cr18Ni9Ti housing, Viton O-ring.
Protection: IP65 with a 100MΩ insulation resistor at 100VDC.

Outline Construction

Detailed dimensions and electric connections are provided for installation guidance.

Order Guide

Pressure range codes are provided from 0A (0-35kPa) to 13 (0-3.5MPa).

Notes

Installation of a tri-valve is recommended for safe and reliable operation.
Horizontal installation of the transducer is suggested.
Ensure the transducer's range and maximum static pressure are suitable for the measured pressure.
Standard cable length is 1.5m; additional length incurs extra cost.
Ensure the pressure in the positive cavity is greater than in the negative cavity.

MDM390 Pieozresistive Differential Pressure Transducer-2

MPM390 Pieozresistive Differential Pressure Transducer(V2.0) Electric Connection Wire color Range code 1. We suggest to install a tri-valve between measured point and transmitter, so that the measured media could be put on positive and negative cavities slowly and equably. This would help transducer work safely and reliably; 2. We suggest to install differential pressure transducer horizontally; 3. Please pay attention that if transducer’s range and max.static pressure could be suitable for measured pressure; 4. Cable length: we provide standard 1.5m cable free of charge, the extra cable should...
