The Vaisala DMT143L Dewpoint Transmitter provides reliable and stable measurements for industrial dryer applications. It is designed for extreme conditions. The DMT143L incorporates the Vaisala DRYCAP thin film polymer sensor and auto-calibration software. The standard sensor choice for dry gases and desiccant dryers is DRYCAP 180M and for more humid applications such as refrigeration dryers, a DRYCAP 180S sensor.
Both the sensors are immune to particulate contamination, water condensation, oil vapor and most chemicals. Because the sensor withstands condensation, its performance is unmatched for low dew point applications that experience process water spikes, such as pipeline condensation during a system failure or start-up.
The auto-calibration software works on-line while the process is running. If the measurement accuracy is not confirmed, corrections are made automatically. The DMT143L adjusts the measurement, corrects dry-end drifts and continues to function. Calibration occurs quickly, and with corrections so minor, it will go unnoticed.
