Vaisala HUMICAPâ Humidity and Temperature Probe HMP7 is designed for
applications that involve constant high humidity or rapid changes in humidity such as
drying and test chambers, combustion air and other humidifiers and meteorological
measurements where measurement performance and chemical tolerance are essential.
Vaisala is the original innovator of the
thin-film capacitive humidity
measurement technology, which has now
become the industry standard in
humidity measurement.
HUMICAPâ technology results from
Vaisala's 40-year experience in industrial
humidity measurement, providing the
best stability, fast response time, and low
hysteresis in a wide range of
applications.
Probe heating functionality heats up not
only the sensor, but the whole probe
head. When probe temperature is heated
above dew point temperature,
condensation on the probe can be
avoided while measuring the dew point
temperature of the process. By setting
the temperature compensation value
obtained, for example, with the TMP1
temperature probe, true relative
humidity at process temperature can be
measured while avoiding condensation
by elevated probe temperature.
Indigo transmitters o„er a variety of
connectivity options through analog
signals or digital outputs, configurable
relays, and wireless (WLAN)
configuration interface, providing a
suitable solution for all industrial
humidity measurements. The cable
length between the probe and
transmitter can be extended to up to 30
meters.
The probe is plug and play compatible
with Vaisala Indigo™ series of
transmitters, or 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.
Each probe is manufactured and
individually calibrated in Vaisala's worldclass facility in Finland. The traceable
factory calibration certificate is included
also in electronic format in the probe.
Validate and maintain the accuracy by
calibrating the instrument on the field, or
use Vaisala's easy and thorough
calibration services.
