Vaisala DRYCAP®
The Vaisala DRYCAP
®
Dewpoint
Transmitter DMT142 is a miniature
dew point measurement instrument.
The transmitter can be installed
directly into pressurized systems at
50 bar (725 psia) maximum pressure.
The long-term high performance
is achieved with Vaisala DRYCAP
®
technology.
The sensor fully withstands getting
wet, and therefore, the transmitter
performs exceptionally well in
applications that occasionally
experience process water spikes,
such as pipeline condensation during
a system failure or start-up. The
sensor is also immune to particulate
contamination, oil vapor and most
chemicals, and is insensitive to the
ow rate.
Long calibration interval
The calibration interval of the
DMT142 is two years. Additionally,
the Vaisala DRYCAP
®
Hand-Held
Dewpoint Meter DM70 can be used
to con rm the performance of the
DMT142 without disconnecting the
transmitter. For any adjustment
needs, the transmitter can be sent to
Vaisala Service.
The auto-calibration software works
on-line while the process is running.
If the measurement accuracy is not
con rmed, corrections are made
automatically.
Easy installation
The DMT142 has a variety of features
to choose from, including different
output and installation options. Due
to its small size and light weight,
the DMT142 is quickly and easily
installed in tight spaces or in small-
size pipelines.
The Vaisala DRYCAP
®
Hand-Held
Dewpoint Meter DM70 is ideal for
confirming the performance of the
DMT142 in the field.
