Versatile outputs he DMT340 can have up to three analog outputs. Galvanic isolation of supply power and analog outputs is also available. For serial interface the USB connection, RS232 and RS485 can be used. Additionally alarm relay option is available. Easy installation he DMT340 has a variety of features to choose from. Units are delivered installation-ready. The DMT340 transmitter family has the solution for demanding industrial dewpoint measurements. he Vaisala DRYCAP" Dewpoint and Temperature Transmitter Series DMT340 is designed for industrial low humidity applications. Typical applications include compressed air drying and metal treatment. he device is very reliable, easy to use and economical to maintain. Stability in low dewpoints he 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 dewpoint applications that experience water spikes in the process. he sensor recovers rapidly from contact with free water. Patented auto-calibration he stability of the DMT340 is due to the unique auto-calibration function, patented by Vaisala. he 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. he procedure is so quick and corrections are so minor that The display shows measurement trends, real time data and history. it will go unnoticed. his 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 he 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. he optional data logger with real-time clock makes it possible to generate more than four years of measured The Vaisala DRYCAP® HandHeld Dewpoint Meter DM70 is ideal for field checking DMT340 transmitters.
