Pioneers in Compressed Air Drying and Filtering. Quality at a Fair Price. 

Our in-house developed dew point sensor provides the ideal platform for air quality monitoring.

Please contact one of our engineers to find out how this technology can be deployed advantageously within your business.


Dew Point Sensor

Tegnon is proud to present its new wall mounted pressure dew point sensor. This high precision dew point sensor utilises a capacitive polymer humidity sensor that is temperature compensated to provide responsive pressure dew point readings.

This sensor caters for a wide temperature and humidity range and is very stable at high humidity levels. Our sensor is pressure resistant up to 16-bar.

The Tegnon dew point sensor incorporates a complete platform for air quality monitoring. As standard the sensor includes a LCD screen that displays real-time relative humidity, pressure dew point and air temperature values. The following communication outputs are available:

  • 0-10V output signal
  • 4-20mA output signal
  • GSM
  • 220VAC alarm signal

The tegnon dew point sensor can be installed with the www.tegnonefficiency.co.za compressed air efficiency monitoring cloud platform. This platform records compressed air flow and quality history in the cloud. It allows our clients to track flow performance.

The www.tegnonefficiency.co.za platform empowers users to react when the air quality changes unexpectedly to ensure that the system can be returned to specification.
