Pressure dew point measurement and display

The DEWMAT 799.230 dewpoint sensor is particularly suitable for long-term reliable monitoring of the dewpoint in industrial processes.

To meet the most demanding applications, the all-new sensor has improved signal integrity and stability.

  • Very low dewpoint sensor down to –60 ° C
  • Great long-term stability
  • Graphic screen
  • Alarm relay
  • IP65 enclosure for demanding industrial applications
  • Very fast reaction times allow safe signaling when the limit values are exceeded
  • Direct installation in a dryer possible via ½ "thread
  • High precision, ± 2 ° C dew point

The measured dewpoint is transmitted via a 4-20 mA signal.

The integrated screen shows the measured value online and the alarm status. It is possible to program an alarm triggering a relay.

DEWMAT 799.230 is a complete device for dew point measurement with sensor, screen, keyboard and alarm output.

All sensor parameters, such as analog output scale, alarm values, units, etc. can be easily adjusted using the service kit. The service kit is connected to the PC via a USB interface.
