The mini dew point sensor is suited to small or compact spaces. Measure pressure dew point (PDP), relative humidity, temperature. Ideal for temporary or permanent installation.

Dryer Types

  • Drum, Hybrid, Membrane, or Refrigerant

Standard Features

  • Pressure Dew Point (PDP) Range: -60°C to +60°C (-76°F to +140°F)
  • IP Rating: IP65
  • Accuracy: ±2%
  • Outputs: Modbus (RS485) and 4-20mA
  • Power Requirement: 10 to 30vDC, max 50 mA @ 24vDC

Options

  • Casing: Aluminum or stainless steel
  • Gas Types: Air, Argon, Carbon Dioxide, Carbon Monoxide, Helium, Hydrogen, Nitrogen, Oxygen

Applications

  • Compressed air and gas systems
  • Process gases
  • Manufacturing, industrial and pharmaceutical use
  • Permanent or temporary installation
  • Non-explosive environments

This compact dew point sensor is suitable for refrigerant, desiccant, drum and membrane dryers. Its proven polymer film technology provides strong contamination resistance. The precision sensor design compensates for drift caused by temperature, contamination and aging, providing long-term, reliable, high-accuracy measurements.

Best Suited to compressed air and gas systems up to 4 MPa (600psi) and small spaces.

Important

  • A minimum flow rate of > 1 L/min is required for the sensor to read accurately
  • This sensor does not measure pressure, nor does it have an alarm relay
  • Relative humidity must not exceed 85%
  • The sensor must be installed in an upright position, after the dryer.
  • Incorrect wiring or installation can damage the sensor and void the warranty. If you aren’t sure how to install or wire the sensor, please contact us. Full installation and wiring instructions are available in the User Manual.
