Documentation Conventions
Throughout the manual, important safety considerations are highlighted
as follows:
WARNING Warning alerts you to a serious hazard. If you do not read and follow
instructions very carefully at this point, there is a risk of injury or even
death.
CAUTION Caution warns you of a potential hazard. If you do not read and follow

Safety
The product delivered to you has been tested for safety and approved as
shipped from the factory. Note the following precautions:
WARNING Ground the product, and verify outdoor installation grounding
periodically to minimize shock hazard.
CAUTION Do not modify the unit. Improper modification can damage the product
or lead to malfunction.
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. It is possible to damage the product,
however, by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench.
- When an ESD workbench is not available, ground yourself to the
equipment chassis with a wrist strap and a resistive connection cord.
- If you are unable to take either of the above precautions, touch a
conductive part of the equipment chassis with your other hand before
touching ESD sensitive components.
- Always hold component boards by the edges and avoid touching the
component contacts.

CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the product features and options.
Introduction to HMP60, HMP110, and HMP110T
Vaisala Humidity and Temperature Probes HMP60 and HMP110 are
simple and cost-effective humidity transmitters suitable for volume
applications, integration into other manufacturers’ equipment, incubators,
glove boxes, greenhouses, fermentation chambers, and data loggers.
HMP60 uses the interchangeable Vaisala INTERCAP®sensor. No
recalibration is required after sensor replacement.
HMP110 uses the Vaisala HUMICAP®180R sensor for increased
accuracy. The HMP110 requires calibration after sensor replacement.
This can be done on the serial line using the optional Vaisala USB cable.

HMP110T is a temperature measurement only version of the HMP110
probe. It has the same temperature measurement performance and
specifications as the HMP110, but is not equipped with a humidity
sensor.

Installation Accessories (Optional)
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.

Figure 3 Probe Mounting Clamp in Use
Probe Mounting Flange
The probe mounting flange is a silicone flange that can be used to hold
the probe in a through-wall installation. The flange is a general purpose
mounting accessory for Ø12mm probes, and comes with a sealing plug
for coaxial cables that is not needed when the flange is used with
HMP60, HMP110 and HMP110T.

Duct Installation Kit
The duct installation kit includes a plastic pipe with a flange (Vaisala
order code: 215619). To install the probe with the duct installation kit,
drill a hole to the duct wall, assemble the probe to the duct installation
kit, slide the probe head through the hole, and attach the flange to the
duct wall with four screws. See page 20 for details.

Loop Power Converter
The loop power converter is an open frame module that converts one
0 ... 2.5 VDC voltage output to a 4 ... 20 mA current output. To use the
loop power converter module, the probe:
- must be in the analog output mode
- the desired quantity must be on channel 1
- channel 1 must be scaled to 0 ... 2.5 V
Wiring instructions are provided in section Wiring with the Loop Power
Converter on page 22.
