Product Description

Product Description

 

Introducing the Vaisala HUMICAP®The Humidity and Temperature Probe HMP4, meticulously designed for high-pressure applications,is perfect for use in compressed air systems, maritime environments, breathing air, and a variety of industrial applications where superior measurement performance and chemical tolerance are of utmost importance.

Features

 

1. Exceptional RH accuracy up to ±0.8 %RH
2. Unmatched temperature accuracy up to ±0.1 °C (±0.18 °F)
3. Wide temperature measurement range from −70 to +180 °C (−94 to +356 °F)
4. Robust operating pressure capability from 0 to 10 MPa (0 to 100 bar)
5. Sensor purge feature ensures improved long-term stability and enhanced chemical resistance
6. Integrated Modbus
â
RTU communication over RS-485
7. Seamlessly compatible with Vaisala Indigo products and Insight PC software
8. Traceable calibration certificate: 6 calibration points for humidity, 1 for temperature

 

Sensor Purge Minimizes Contaminant EffectsIn environments with elevated
concentrations of chemicals and cleaning agents,
the sensor purge option effectively helps
in maintaining measurement accuracy
between calibration intervals.
The sensor purge involves heating the
sensor to thoroughly remove harmful chemicals. This function can be manually initiated or programmed to occur at specific intervals.

Flexible Connectivity The probe can function as a standalone
digital Modbus RTU transmitter over an
RS-485 serial bus. It is also
compatible with Indigo transmitters and the
Indigo80 handheld indicator. For convenient
access to field calibration, device
analytics, and configuration,
connect the probe to Vaisala
Insight software for Windows
.
