Product Description

Vaisala Dew Point and Pressure Transmitter DPT146 for compressed air makes monitoring compressed air simple and convenient. DPT146 measures both dew point and process pressure simultaneously, and is the ideal choice for anyone using or

monitoring compressed air.

Features

1. The first transmitter that monitors both dew point and process pressure

2. A simple and convenient transmitter for monitoring of compressed air

3. Highly accurate humidity information thanks to dew point data coupled with live pressure input

4. Proven sensor technology

5. Compatible with Vaisala Handheld Meter DM70 for easy spot- checking, local display, and data logging

Simple and efficient installation

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.

 

Make more informed decisions

Dew point measurement combined with process pressure measurement others further unique advantages. When dew point data is coupled with live pressure input,conversions to atmospheric pressure or ppm are available online, leaving no ambiguity in the information. As an example, regulative requirements of medical gas can be fulfilled easily and quickly.
 

A unique combination of two world-class sensors

DPT146 combines the knowledge of more than 20 years of sensor technology development. Proven measurements from DRYCAPâ sensor for dew point and BAROCAPâ sensor for pressure are now combined into one easy-to-usetransmitter.

 

Convenience with proven performance

Well-developed technology brings both proven results and convenience. Spot-checking and verification of dew point is easy thanks to fully compatible Vaisala

DRYCAPâ Handheld Dew Point Meter DM70. The meter can also be used as a local display and data logger.

Temperature measurement is available when RS-485 is in use.
