Overview

The MDM291 Water Differential Pressure Sensor is a robust industrial differential pressure sensing element designed for accurate measurement of differential pressure in water and other fluid systems. Built with a fully welded 316L stainless steel structure, it features temperature-compensated performance and high reliability for demanding process control environments. The sensor transmits pressure data through an isolated diaphragm and silicone oil to a high-precision silicon chip, producing a linear output signal suitable for process control, calibration, and industrial pressure monitoring applications.

Specification

  • Model: MDM291 Water Differential Pressure Sensor
  • Measurement Type: Differential pressure
  • Pressure Range: 0 bar ~ 0.35 bar … up to 20 bar
  • Construction: Fully welded design (no O-ring sealing)
