PRODUCT OVERVIEW
This chapter introduces the features and advantages of Dewpoint
Transmitter DMT152.
Introduction to Dewpoint Transmitter DMT152
The Vaisala DRYCAP
®
dewpoint transmitter DMT152 measures
dewpoint temperature accurately in a measurement range from
-80 ºC to -10 ºC (-112 … +14 °F). The maximum output range of the
transmitter is -100 … +20 °C (-148 … +68 °F).
The DMT152 is designed for a wide range of OEM applications. The
transmitter is easy to install, and the mechanics have been designed for
harsh environments requiring protection against dust, dirt, and splashed
water.
The excellent stability and reliability of the transmitter’s performance is
based on advanced DRYCAP
®
polymer sensor technology. The
DRYCAP
®
technology has low maintenance needs due to its excellent
long term stability and durability against condensation. For more
information on DRYCAP
®
technology, refer to chapter Functional
Description on page 13.
