The Vaisala DRYCAP® Dewpoint and Temperature Transmitter Series DMT340 is designed for industrial low humidity applications. Typical applications include compressed air drying and metal treatment. The device is very reliable, easy to use and economical to maintain.
Stability in Low Dew Points
The Vaisala DRYCAP® Sensor is immune to particulate contamination, water condensation, oil vapor and most chemicals. Since the sensor withstands condensation, its performance is unmatched for low dew point applications that experience water spikes in the process. The sensor recovers rapidly from contact with free water.
The stability of the DMT340 is due to the unique auto-calibration function, patented by Vaisala. The auto-calibration makes the transmitter perform a calibration and adjustment by itself while the measured process is running. If the measurement accuracy is not confirmed, corrections are made automatically. The procedure is so quick and corrections are so minor that it will go unnoticed. This ensures low maintenance and high performance. To continue performance at the highest level, the transmitter can be sent to Vaisala for a NIST traceable calibration. Calibration intervals depend on the application; in normal conditions, a NIST traceable calibration in every two years is recommended.
Graphical Measurement Trend and History Display
The DMT340 can be ordered with a large numerical and graphical display with a multilingual menu. It allows the user to monitor measurement trends and one-year history. The optional data logger with realtime clock makes it possible to generate more than four years of measured history and zoom in on any desired time or time frame. The display alarm allows tracking of any measured parameter, with a freely configurable low and high limit.
