Dewpoint Transmitters

for high temperature applications


The DRYCAP Dewpoint and Temperature Transmitters DMT345 and DMT346 measure dewpoint and mixing ratio directly in high temperature drying processes. TheDMT345 probe is designed for direct measurement in temperatures up to 180°C. The optional installation flange allows for adjustable installation depth. In addition to measuring dewpoint and mixing ratio, it measures temperature and relative humidity. The DMT346 probe is constructed for humidity measurement in process temperatures between140 and 350°C. The standard cooling set accomplished system cooling without moving parts, additional power or cooling utilities. The sensorrecovers quickly after getting wet and is immune to particulate contamination, condensation, oil vapor and most chemicals. Due to the auto-calibration feature, both transmitters have a low maintenance need. The auto-calibration detects on-line possible measurement inaccuracies and automatically corrects dry-end drift in calibration. The display with a multilingual menu allows the user to monitor operational data, measurement trends and up to 1-year measurement history.
