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.

Chapter 1 _________________________________________________________ General Information
VAISALA_________________________________________________________________________ 7
CAUTION
Caution warns you of a potential hazard. If you do not read and follow
instructions carefully at this point, the product could be damaged or
important data could be lost.
NOTE
Note highlights important
information on using the product.
Safety
The product delivered to you has been tested for safety and approved as
shipped from the factory. Note the following precautions:
CAUTION
Do not modify the unit. Improper modification can damage the product
or lead
to malfunction.
NOTE
Before you connect
an HMP60 or HMP110 series probe to a device, it is
recommended to power off the device.
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 features and options of the HMP60 and
HMP110 series probes.
Introduction to HMP60 and HMP110 Series
Vaisala Humidity and Temperature Probes HMP60 and HMP110 Series
are simple and cost-effective humidity transmitters suitable for various
volume applications:
- Integration into other manufacturers’ equipment.
- Incubators.
- Glove boxes.
- Greenhouses.
- Fermentation chambers.
- Data loggers.
- Hand-held meters.
HMP60 series probes use the interchangeable Vaisala INTERCAP®
sensor. No recalibration is required after sensor replacement.
HMP110 series probes use the Vaisala HUMICAP®180R sensor for
increased accuracy. HMP110 series probes require calibration after
sensor replacement. This can be done on the serial line using the optional
Vaisala USB cable.

Installation Accessories (Optional)
For order codes, see section Options and Accessories on page 72.
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.
1001-138
Figure 4 Probe Mounting Clamp in Use
The probe mounting clamp is delivered in two parts that must be
connected when it is used:
1. Align the slots on the clamp parts as shown in Figure 5 below.

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
and HMP110 series probes.

Figure 8 Probe Mounting Flange
Plastic Locking Bushing for HMP63 and
HMP113
HMP63 and HMP113 can be connected to compatible Vaisala
instruments using a plastic locking bushing that is placed over the probe.
The bushing has a M15x1 thread. It is compatible with the HMT120 and
HMT130 transmitters, and the HM40 hand-held meter.

Duct Installation Kit for HMP60, HMP110,
HMP110D and HMP110T
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 22 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 is 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 26.
