The Vaisala DRYCAP® Dewpoint Transmitters DMT345 and DMT346 are designed for humidity measurement in industrial drying applications with particularly high temperatures. Both transmitters incorporate the Vaisala DRYCAP® sensor, which is accurate, reliable, and stable. The sensor is condensation-resistant and is immune to particulate contamination, oil vapor, and most chemicals. The DRYCAP® sensor is notable for its swift response time and rapid recovery after getting wet.
♦ The DMT345 measures humidity at temperatures up to180 °C (356 °F)
♦ The DMT346 measures humidity at temperatures up to 350 °C (+662 °F)
♦ Dew point accuracy ±2 °C (±3.6 °F)
♦ Vaisala DRYCAP® sensor provides accurate and reliable measurement with excellent long-term stability and fast response time
♦ Unique auto-calibration feature
♦ NIST traceable calibration (certificate included)
♦ Graphical display and keypad for convenient operation
♦ Optional alarm relays and mains power supply module
♦ Analog outputs, RS232/485, WLAN/LAN
♦ MODBUS protocol support (RTU/TCP)
The DMT345 and DMT346 are built for direct measurement in hot processes. Therefore, there is no need for sampling systems and trace heating. As a result, high measurement accuracy and constancy are maintained. The accuracy and stability of the DMT345 and the DMT346 are due to their unique auto-calibration function, developed by Vaisala.
The DMT345 is designed for accurate humidity measurement in hot and dry conditions. This model provides unmatched dry-end measurement accuracy at temperatures up to 140 °C; however, it can operate safely at temperatures up to 180 °C.
