Chapter 2 – Product overview
2. Product overview
HMP series probes are humidity and temperature measurement probes with a digital output
(Modbus protocol). The probes are designed for demanding humidity and temperature
measurement applications. The probes have a two-part structure, with measurement
electronics contained in the probe body and sensor(s) in the probe head. The probe body and
the probe head are connected by a cable. Length options for this connecting cable depend on
the probe model.
The probes are compatible with Vaisala Indigo transmitters. They can also be connected to
Vaisala Insight software for configuration, calibration, adjustment, diagnostics, and temporary
online monitoring.

3. Installation
When you choose the installation location for the probe, consider the following:
• Verify the operating environment specification of the probe model. The probe head
typically has a much wider operating temperature range than the probe body.
• If the temperature of the measured environment diers greatly from ambient
temperature, the entire probe head and preferably plenty of cable must be inside the
measured environment. This prevents measurement inaccuracy caused by heat
conduction along the cable.
• Probe mounting options are model-specific.
Figure 2 Example installation
Mount the probe head horizontally to prevent any water condensing on the probe head
1
from running to the sensors.
2 Let the cable hang loosely to prevent condensed water from running along the cable to
the probe body or probe head.
3 Attach the probe body to a wall or other surface using the two mounting clips (Vaisala
item 243257SP) supplied with the probe. Each clip attaches to the installation surface with
one screw (screw hole Ø 4.2 mm).
4 Cable to Modbus master or Indigo transmitter.
CAUTION!

Chapter 3 – Installation
Vaisala HUMICAPâ Humidity and Temperature Probe HMP3 is a general purpose probe
designed for various industrial processes. The probe structure allows for replacing the sensor
without tools, making it suitable for applications such as paint booths and other industrial
applications where periodic recalibration alone is not sucient for maintaining the probe
performance. Other suitable applications include, for example, industrial HVAC systems,
cleanrooms, and environmental chambers.
• Operating temperature for probe head −40 … +120 °C (−40 … +248 °F)
• Operating temperature for probe body −40 … +80 °C (−40 … +176 °F)
If purchased with a composite sensor instead of the field replaceable HUMICAPâ R2 sensor,
HMP3 can use the chemical purge feature. In environments with high concentrations of
chemicals and cleaning agents, the chemical purge option helps to maintain measurement
accuracy between calibration intervals.

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.
Probe heating
HMP7 supports probe heating. Probe heating heats up not only the sensor, but the entire
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.
• Temperature measurement range −70 … +180 °C (−94 … +356 °F)
• Operating temperature of probe body −40 … +80 °C (−40 … +176 °F)
• Probe heating and sensor warming functions minimize condensation on probe
• Vapor and pressure proof construction

Chapter 3 – Installation
If probe heating is enabled, output parameters that are dependent on temperature
measurement (such as relative humidity) are locked whenever probe is heated unless the true
temperature of the measured environment is updated to the temperature compensation
register of the probe from another measurement instrument (for example, the TMP1 probe).
Output parameters such as dew point temperature that can be measured or calculated
without this external temperature information are available even without the temperature
input.

3.7 MMP8 probe
Figure 11 MMP8 dimensions
Vaisala HUMICAPâ Moisture in Oil Probe MMP8 enables fast and reliable measurement of
moisture in oil. It uses proven Vaisala HUMICAPâ sensor that was developed for demanding
dissolved moisture measurements in transformer and lubrication oils, hydraulic fluids, and
other liquids.
MMP8 measures dissolved moisture in oil in terms of the water activity (aw), relative saturation
(%RS), and temperature (T). Water activity or relative saturation indicate directly whether
there is a risk of free water formation. This data is relevant in lubrication oil applications where
detecting water ingress and preventing free water formation is crucial. The measurement is
independent of oil type and age.

MMP8 can also output ppm, the average mass concentration of water in oil. Vaisala has this
conversion readily available for specific oils, including mineral transformer oil. This allows
continuous measurement of ppm concentration in power transformer condition monitoring.
• Temperature measurement range −40 … +180 °C (−40 … +356 °F)
When installed with the ball valve kit, the MMP8 is ideal for installation into processes where
the probe needs to be installed or removed while the process is running. Probe installation
depth is adjustable. Pressure fitting options are ISO 1/2" and NPT 1/2". MMP8 is delivered with
a manual pressing handle that allows the probe to be pushed against process pressure.
For installation instructions of the ball valve see Attaching ball valve kit to process (page 20).
