Product Description

Vaisala DRYCAPâ Dew Point and Temperature Probe DMP8 is designed for industrial low-humidity applications such as industrial drying, compressed air systems, and semiconductor industry. It can be installed in a 1/2" NPT or ISO thread with adjustable insertion depth.

Features

1. Dew point measurement range −70 … +80 °C (−94 … +176 °F) Td/f

2. Dew point measurement accuracy up to ±2 °C (±3.6 °F) Td/f

3. Operating pressure of probe head 0 … 4 MPa (0 … 40 bar)

4. Operating pressure 0 … 10 MPa (0 … 100 bar)
 

5.  Adjustable installation depth

6.  Tolerates condensation, oils, dust,and most chemicals

7. Sensor purge improves long-term stability and chemical resistance

8. Modbus RTU over RS-485
 

9. Compatible with Vaisala Indigo products and Insight PC software

10. Traceable calibration certificate

Stability at low dew points

The 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. Outstanding stability

provides a long calibration interval.

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.

The 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 easy-to-use access to field calibration, device analytics, and configuration functionality, the probe can be connected to Vaisala Insight software for Windows.
