2. Product Overview
2.1 Introduction to HMM100 Series
Humidity Modules
Figure 1 HMM100 Humidity Module with Probe
The HMM100 series humidity measurement modules are open frame modules intended for
integration into environmental chambers and other chambers where high temperature
tolerance is important. The modules provide a single analog output channel for relative
humidity (RH) or dewpoint (Td). Dewpoint is the recommended quantity if the measurement
environment has significant temperature dierences.
Table 4 Quantities Measured by HMM100
Quantity Range
Relative humidity (RH) 0 ... 100 %
Dewpoint (Td) -20 ... +100 °C (-4 ... +212 °F)
All HMM100 modules include automatic temperature compensation across the operating
temperature range using an integrated Pt1000 sensor. No external temperature
compensation should be applied to the output.
HMM100 modules do not incorporate probe heating or chemical purge functionality. If the
measurement environment is prone to condensation, or likely to cause chemical
contamination of the sensor, other Vaisala instruments may be more suitable to the
application.
Chapter 2 – Product Overview

The cable and probe of the HMM100 are attached at the factory. They should remain
connected to the module at all times; do not cut and re-connect the cable.

2.3 Probe Types
The HMM100 can be ordered with a plastic or stainless steel probe. The plastic probe is
available in two sizes, a standard one and an extended 400-mm-long option. The plastic
probe is suitable for most applications.
The standard plastic probe and the steel probe have the same operational temperature
range (-70 °C to +180 °C). The extended 400-mm plastic probe is suitable for temperatures
ranging from -70 °C to +120 °C. Note that the operational temperature range is also aected
by the filter; see Filter Types (page 11).
Figure 2 (page 11) shows the plastic probe with a membrane filter (top), and the stainless
steel probe with a sintered stainless steel filter (bottom).

2.4 Filter Types
All filters available for HMM100 are 12 mm in diameter, and can be used in both the plastic
and stainless steel probe. Note the operational temperature range of each filter. For order
codes, see Accessories (page 62).

2.5 Installation Accessories
For order codes of installation accessories, see Accessories (page 62).
2.5.1 Probe Mounting Flange
The probe mounting flange is used to seal the cable pass-through in the chamber wall. The
flange can also be used to hold the probe itself, in case the probe cannot be mounted on the
chamber wall otherwise. This mounting is not ideal since leaving the probe cable completely
outside the measurement environment may cause heat conduction that aects the
measurement. Therefore, installation using mounting flange is recommended for the 400-
mm-long probe option only, as the risk of heat conduction to the sensor is smaller than with
the shorter, standard-length probe.
Figure 4 Optional Probe Mounting Flange
HMM100 User Guide M211024EN-D
12

2.5.2 Probe Mounting Clamp
The optional mounting clamp makes it easy to install the probe on the wall of the
measurement environment. The probe can be detached for calibration simply by loosening
the lower screw.
Installing the entire probe in the measurement environment prevents heat conduction to the
sensor, and is the recommended installation method.
Figure 5 HMM100 Probe with Mounting Clamp
Use 2 mounting clamps for stability when installing the longer, 400-mm plastic probe.
More Information
‣Mounting HMM100 Probe to Mounting Clamp (page 19)
2.5.3 Mounting Bracket with Lid
The optional mounting bracket includes a metal backplate and a plastic lid for the
component board. The bracket does not provide IP rated protection. The bracket can be
installed on a DIN rail.
Chapter 2 – Product Overview

Figure 6 Mounting Bracket with Lid
2.5.4 Module Housing (IP65)
The optional module housing is an IP65 rated housing. The module is installed inside the
housing in a mounting bracket (provided with the housing). The housing has two cable
glands. A coaxial plug is provided for sealing the gland for the probe cable.
Figure 7 Optional Module Housing
2.6 Safety
The module delivered to you has been tested for safety and approved as shipped from the
factory. Note the following precautions:
Ground the product and verify installation grounding periodically to
minimize shock hazard.
WARNING!
HMM100 User Guide M211024EN-D
14

Do not modify the unit or use it in ways not described in the documentation.
Improper modification may lead to safety hazards, equipment damage, failure to
perform according to specification, or decreased equipment lifetime.
CAUTION!
2.6.1 ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits.
Vaisala products are adequately protected against ESD for their intended use. However, it is
possible to damage the product by delivering an electrostatic discharge when touching,
removing or inserting any objects inside the equipment housing.
Avoid touching component contacts or connectors when working with the device.
2.7 Regulatory Compliances
The HMM100 is in conformity with the provisions of the following EU directive(s):
• RoHS Directive
• WEEE Directive
The electromagnetic compatibility of the HMM100 has been tested according to the
following product family standard:
EN61326-1 Electrical equipment for measurement, control and laboratory use - EMC
requirements - for use in light industrial environments.
The Electrostatic Discharge test (EN 61000-4-2) was not applied to the open frame module.
In the final product the module PC-board should be installed in a user restricted location /
enclosure for continued ESD protection.

3.2 Installing the Module
The measurement probe with cable is attached to the component board at Vaisala. Do not
disconnect and reconnect the cable.
1. Attach the module securely using the mounting holes on the corners of the component
board. Use the optional mounting bracket (Vaisala order code 225979) if needed.
2. Make sure that the module has a good earth connection from the plated mounting hole.
The installation holes on the component board are compatible with Vaisala HMM22 and
HMM30 humidity modules. Remember to disable temperature compensation (if any) in
the measurement system when replacing an old module with the HMM100. The
temperature compensation in the HMM100 is always enabled.

3.3 Installing the Probe
1. Select the mounting location for the probe.
• The probe should be entirely in the measurement environment, with sucient
distance to the outer walls of the chamber or duct. Air should flow freely around the
probe.
• The probe location should represent well the environmental or process conditions,
and it should be as clean as possible.
