PM4 Series M4 mounting miniature pressure sensor

Miniature titanium pressure sensor with M4 mounting for static and dynamic pressure measurements. Designed for harsh environments and compatible with corrosive or conductive fluids.


Key features

  • Pressure ranges from 5 to 200 bar
  • Static and dynamic pressure measurement
  • Fully made in titanium
  • Flush membrane sensor design
  • M4x0.7 mechanical connection
  • Operating temperature from -40°C to +120°C

Performance highlights PM4 Series

The PM4 Series M4 mounting miniature pressure sensor is designed for static and dynamic pressure measurements in harsh environments. The sensor is fully made in titanium. Its flush membrane design makes it compatible with many corrosive and conductive fluids.

Usage conditions

The sensor is suitable for any liquid or gas compatible with titanium. It supports relative or sealed pressure types, depending on the selected pressure range. The operating temperature range is -40°C to +120°C. Standard compensated temperature range is 0°C to +60°C, with other ranges available as options.

Possible applications

  • Pressure measurement in harsh environments
  • Corrosive fluid pressure monitoring
  • Conductive fluid pressure measurement
  • Compact OEM pressure systems
  • Static pressure testing
  • Dynamic pressure testing

Advantages of choosing this product

The PM4 Series M4 mounting miniature pressure sensor combines compact size with a titanium construction. This supports use in demanding fluid and gas applications. The M4x0.7 mechanical connection helps engineers integrate the sensor in compact assemblies where space is limited.

Other important features

  • Pressure ranges from 75 to 3000 psi
  • Overpressure rating of 2 x pressure range
  • Burst pressure rating of 5 x pressure range
  • Resonant frequency up to 673 kHz
  • Recommended mounting torque of 1.8 Nm
  • IP50 standard, IP67 optional
