Vaisala DRYCAP
â
Vaisala DRYCAP â Dew Point Transmitter
DMT143 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.
â
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 highly resistant to
particulate contamination, oil vapor, and
most chemicals, and is insensitive to
the flow rate.

Long Calibration Interval
The calibration interval of DMT143 is two
years. Additionally, Vaisala DRYCAP
Handheld Dew Point Meter DM70 can be
used to confirm the performance of
DMT143 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
confirmed, corrections are made
automatically.

Easy Installation
DMT143 has a variety of features to
â choose from, including different output
and installation options, and alarm LED.
Due to its small size and light weight,
DMT143 is quickly and easily installed in
tight spaces or in small-size pipelines.
The alarm LED indicates too high dew
point in the process. The trigger point is
preset at the factory. It can be later
adjusted with Vaisala DRYCAP
Handheld Dew Point Meter DM70, or the
convenient Vaisala Insight PC software
for Windows â . Insight PC software can
also be used for other configuration
options (see www.vaisala.com/insight).
