Vaisala DMPXPROBE6 DMP6 Dew Point and Temperature Probe for In-Line Measurement in Very High Temperature Applications with 2m Cable

DRYCAP® Dew Point and Temperature Probe DMP6 is designed for in-line humidity measurement in industrial drying applications with very high temperatures and a wide dew point range. A high temperature tolerance is achieved using a passive cooling set that conducts heat away from the probe and reduces the temperature to within the optimal range for the sensor.

DMP6 incorporates the Vaisala DRYCAP® sensor, which is accurate, reliable, and stable. The sensor is condensation-resistant and immune to particulate contamination, oil vapor, and most chemicals. Sensor warming minimizes the risk of condensation accumulating on the sensor. If the DRYCAP® sensor does get wet, it dries rapidly and recovers its swift response time. In low-humidity conditions the sensor will auto-calibrate to ensure accurate measurement.

DMP6 is part of the Indigo family and is compatible with Indigo500, Indigo300 and Indigo200 series transmitters. It can be used with the Vaisala Insight PC software for data visualization, easy probe configuration, and self-calibration.

• Long (two-year) calibration interval for easy maintenance

Measure humidity directly in very hot processes

DMP6 is built for direct measurement in temperature range +100 … +350 °C (+212 … +662 °F). There is no need for a sampling system or trace heating. To tolerate these high temperatures, the probe head is inserted inside a cooling set that provides passive cooling. The cooling set has removable cooling fins that allow the operating temperature profile of the probe to be adjusted so that adequate cooling is provided for each application. The cooling system has no moving parts and requires no additional power or cooling utilities, so there is no risk of sensor damage due to mechanical cooling failure. DMP6 incorporates the Vaisala DRYCAP® sensor, which is accurate, reliable, and stable. The sensor is condensationtolerant and immune to particulate contamination, oil vapor, and most chemicals. Sensor warming minimizes the risk of condensation accumulating on the sensor. If the DRYCAP® sensor does get wet, it will rapidly dry and recover its swift response time.

Sensor purge minimizes effects of contaminants

In environments with high concentrations of chemicals and cleaning agents, the sensor purge option helps to maintain measurement accuracy between calibration intervals. Sensor purge involves heating the sensor to remove harmful chemicals. The function can be initiated manually or programmed to occur at set intervals. Flexible connectivity The probe can be used as a standalone digital Modbus RTU transmitter over an RS-485 serial bus, and it can also be connected to Indigo transmitters and the Indigo80 handheld indicator. For easyto-use access to field calibration, device analytics, and configuration functionality, the probe can be connected to Vaisala Insight software for Windows.

Vaisala Indigo product family

Indigo transmitters extend the capabilities of Indigo-compatible measurement probes. The transmitters can display measurements on the spot as well as transmit them to automation systems through analog signals, digital outputs, and relays.
