DMP7 Dew Point and Temperature Probe - 1

DMP7 Dew Point and Temperature Probe For Installations in Tight Spaces Features • Dew point measurement range -70 ... +80 °C (-94 ... +176 °F) Td/f • Dew point measurement accuracy up to ±2 °C (±3.6 °F) Td/f • Sensor purge provides superior chemical resistance • Tolerates condensation, oils, dust, and most chemicals • Modbus RTU over RS-485 • Compatible with Indigo transmitters and Insight PC software • Traceable calibration certificate Vaisala DRYCAP® Dew Point and Temperature Probe DMP7 is designed for low-humidity applications. Thanks to its short probe length, it fits in installations with limited space such as semiconductor manufacturing equipment. Other applications include industrial drying, compressed air systems, dry rooms, and blanket gases in metal heat treatment. Stability at Low Dew Points Vaisala DRYCAP® sensor is immune to particulate contamination, water condensation, oil vapor, and most chemicals. The sensor tolerates condensation and recovers perfectly if exposed to liquid water. Fast reaction time and stability make its performance unmatched also in dynamic and low dew point applications. Chemical Purge Minimizes Effects of Contaminants In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals. The chemical purge involves heating the sensor to remove harmful chemicals. The function can be initiated manually or programmed to occur at set intervals. Pressure-Tight Installation Optional pressure-tight Swagelok fitting is available for DMP7. When installed using the fitting DMP7 is suitable for installations with pressure in range 0 . 10 bar (0 . 145 psia). Flexible Connectivity The probe is compatible with Vaisala Indigo series of transmitters, and it can be used as a standalone digital Modbus RTU transmitter over RS-485 serial bus. For easy-to-use access to field calibration, device analytics, and configuration functionality, the probe can be connected to Vaisala Insight software for Windows®: see insight.
