Dew Point Probe DMP8 Dew Point Probe DMP8

Smart Dew Point Probe DMP8

with adjustable installation depth for pressurized pipelines <40 bars

Vaisala DRYCAP® Dew Point and Temperature Probe DMP8 is designed for industrial low-humidity applications with pressure up to 40 bars. Typical applications include industrial drying, compressed air systems, and applications in the semiconductor industry.

DMP8 can be installed in a 1/2" NPT or ISO thread with adjustable insertion depth. An optional ball-valve installation kit allows the probe to be inserted or detached from a pressurized line.

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

Key Benefits

Measure dew point directly in very hot processes

DMP6 is built for in-line dew point measurement in very hot processes, between 100...350 °C (+662 °F). Best measurement performance is achieved at process temperatures between 100 °C and 350 °C. 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.

The installation is simple, as the probe can be directly placed in the process. With in-line measurement, there is no need for a sampling system or sample line trace heating.

Vaisala DRYCAP® Sensor for accurate and reliable measurements

The Vaisala DRYCAP® sensor is accurate, reliable and stable. It is condensation-resistant and is 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 from getting wet. Due to the unique auto-calibration functionality accurate and stable measurement is ensured.

The chemical purge involves periodic heating of the sensor to remove harmful chemicals. In environments with high concentrations of chemicals and cleaning agents, it helps to maintain measurement accuracy between calibration intervals.

Use standalone or with an Indigo Transmitter

The DMP6 is part of the Vaisala Indigo family, so it can also be used with the Vaisala Indigo series transmitters. The transmitters offer various additional benefits such as display for data visualization, easy access to probe configuration, as well as more extensive options for automation system connectivity, supply voltage and wiring.

Built-in Modbus RTU over RS-485 output means that the DMP6 can be used as a standalone device, and can be easily integrated into third party systems.​

Whether using the DMP6 standalone or with an Indigo transmitter, it can be connected to the Vaisala Insight PC software for easy field calibration, probe configuration and device analytics.​
