DPT146 Dewpoint and Pressure Transmitter for Compressed Air Systems

The DPT146 measures both dew point and process pressure simultaneously, and is the ideal choice for anyone using or monitoring compressed air. For the first time, dew point data – whether calculated to atmospheric pressure or providing ppm – is constantly pressure compensated online and in real-time so there is no ambiguity in the information. One transmitter providing two of the most important compressed air measurements means reduced installation costs and a much easier setup – with only one instrument needing connection and wiring.

Included in the package

  • ISO9001 compliant factory calibration certificate
  • 3 m (10 ft) analog output and power supply cable with threaded connector
  • User's Guide, multiple languages
