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 to 4 Mpa (600psi)
- Refrigerant, Drum and Membrane dryers operating above -40°C (-40°F)
- Dew point range of -60°C to +60°C (-76°F to +140°F)
- Cost sensitive applications
- Small spaces
- Flow rates greater than 1 L/min
- Permanent or temporary installation
Key Features of the Mini Dew Point Sensor
- Suitable for Refrigerant, Drum and Membrane dryers, up to 4 Mpa (600psi)
- Dew Point Measurement Range: -60°C to +60°C (-76°F to +140°F)
- Accuracy +/- 2°C
- Fast response time
- Strong contamination resistance
- Aluminium or Stainless Steel Casing
- Dimensions: 107 mm long x 28 mm wide (4.2″ x 1.1″)
- Modus and 4-20mA outputs
- Measure:
- Pressure Dew Point (PDP)
- Gas temperature
- Relative humidity
Important
- A minimum flow rate of > 1 L/min is required for the sensor to read accurately
- This sensor does not measure pressure
- 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, pleasecontact us. Full installation and wiring instructions are available in the User Manual.
Mini Dew Point Sensor comes with:
- Measurement Chamber with adjustable silencer and removable Nitto type quick connect
(contact us for other measurement chamber options) - M8 connector, 5 pin
- 5 meter data cable
- Calibration certificate
- User Manual
- 12 month warranty
Options for the Mini Dew Point Sensor
- Casing: Aluminium or stainless steel
- Gas Types: Air, Argon, Carbon Dioxide, Carbon Monoxide, Helium, Hydrogen, Nitrogen, Oxygen
- Contact us for other measurement chambers or cable lengths.
Warranty & Calibration
12 month warranty
Calibration is recommended every 2 years (provided the sensor is not exposed to relative humidity above 85%).
Annual calibration is required if the sensor is exposed to relative humidity above 85%.
