The Vaisala DPT146 dew point and pressure transmitter is the ideal choice for anyone using or monitoring compressed air. As the first transmitter that monitors both dew point and process pressure simultaneously, the DPT146 provides two of the most important compressed air measurements meaning reduced installation costs and a much easier setup – with only one instrument needing connection and wiring.
Dew point measurement combined with process pressure measurement offers further unique advantages. 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. Additionally, temperature measurement is also available when the RS485 serial line is in use.
The DPT146 combines the knowledge of more than 20 years of sensor technology development. Proven measurements from the DRYCAP® sensor for dew point and the BAROCAP® sensor for pressure provide accurate measurements. The DPT146 is fully compatible with the Vaisala DM70 hand-held dewpoint meter. The DM70 can also be used as a local display and data logger for monitoring all measured parameters.
