Vaisala Launches Revolutionary Polymer Sensor For Dewpoint To -112 °F

Woburn, MA - The Vaisala DRYCAP Dewpoint Transmitter DMT152 uses a new, ground-breaking polymer sensor technology to measure dewpoint temperatures down to -112°F. The new sensor combines the proven stability and durability of Vaisala's existing thin-film polymer DRYCAP sensor with a vastly expanded measurement range. Previous versions of polymer sensors could only measure dewpoint temperatures as low as - 76 °F. All Vaisala polymer sensors are well known for their ability to withstand condensation and to recover from liquid water exposure. Until the launch of the DRYCAP DMT152 technology, these benefits were unattainable in the very dry measurement ranges.

The DMT152 dewpoint transmitter relies on patented AUTO-CALIBRATION, which provides long term measurement accuracy and durability. Auto-calibration also provides impressive wet to dry response time, measured in minutes instead of hours or days. The DMT152 mechanics are designed to withstand harsh environments that require protection against dust, dirt and splashed water.

Typical industries and applications where this technology can be applied include desiccant air dryers, glove boxes and other dry chamber applications, SF6 gas in high-voltage switchgear, and any inert gases where measuring very low water vapor content is required.
