Product Description

 

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 installationOne 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 DRYCAP
â
sensor for dew point and
BAROCAP
â
sensor for pressure are now
combined into one easy-to-use
transmitter.
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
DRYCAP
â
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.
