Introduction to HMDW110 Series
HMDW110 series transmitters are accurate humidity and temperature transmitters for
measurements in HVAC and cleanroom applications. The series consists of the following
models:
• HMD110/112 models for installation in ventilation ducts
• HMW110/112 models for wall installation
• HMS110/112 models for outdoor use
HMDW110 transmitters can be ordered as:
• Loop powered models, with 2-wire current outputs for humidity and temperature
• Separately powered models, with RS-485 Modbus RTU output
HMD112, HMW112, and HMS112 are standard models that are preconfigured for current output at
the factory. HMD110, HMW110, and HMS110 are factory configurable models that are delivered
with customer specific output settings, including calculated humidity parameters and special
scaling of current outputs, or factory activated Modbus RTU functionality.
Loop powered current output models can be connected to Vaisala Remote Display Panel
RDP100 for real-time viewing of the measurements. HMDW110 series can also supply the
operating power to the display using only the loop power from the outputs.
HMDW110 series transmitters oer several output parameters. Relative humidity (RH) and
temperature (T) are the measured parameters, the others are calculated based on RH and T.
Check the type label on your transmitter to verify its output parameters and scaling of the
output channels.
Table 1 HMDW110 Series Output Parameters
Parameter Symbol Units Description
Temperature T °C
°F
Temperature in Celsius or Fahrenheit scale.
Relative humidity RH % Ratio of the partial pressure of water vapor in the air to the
saturation vapor pressure of air at current temperature.
Dew point Td/f °C
°F
Temperature at which the water vapor in the air will
condense into water at the current pressure. When the dew
point is below 0 °C, the transmitter outputs frost point (Tf)
instead of dew point.
Enthalpy h kJ/kg
BTU/lb
Sum of the internal energy of a thermodynamic system.
Wet bulb
temperature
Tw°C
°F
The minimum temperature that can be reached by
evaporative cooling in the current conditions.

HMD110/112 Installation
• Medium size crosshead screwdriver (Pozidriv) for screws on cover and flange
• Small slotted screwdriver for screw terminals
• Drill with 2.5 mm and 13 mm bits for making the installation holes
• Tools for cutting and stripping wires
• 19 mm open-end wrench for tightening the cable gland

Figure 1 HMD110/112 Installation
1. Remove the yellow transport protection cap and separate the fastening flange from the
transmitter.
2. Use the flange to mark the location and size of the installation holes on the side of the
duct.
3. Drill the installation holes in the duct. Secure the fastening flange to the duct with the two
screws (included).

4. Push the probe of the transmitter through the flange and into the duct. The probe should
reach far enough so that the sensor is located in the middle of the duct.

5. Secure the transmitter to the flange by tightening the screw on the flange that holds the
probe in place.
6. Open the transmitter cover, and route the cables through the cable glands. Connect the
wires to the screw terminals according to the wiring instructions.
7. Tighten the cable gland(s) and close the transmitter cover.

HMW110/112 Installation
• Medium size crosshead screwdriver (Pozidriv) for cover screws.
• Small slotted screwdriver for screw terminals.
• Two installation screws: Ø ≤3.5 mm, head Ø ≤8 mm.
• Depending on the wall material and screw type, you may need a drill and a
suitable drill bit to make installation holes for screws.
• Tools for cutting and stripping wires.
• 19 mm open-end wrench for tightening the cable gland.

1. Open the transmitter cover and use two screws (not included) to attach the transmitter to
the wall. The probe and cable gland should point down.
2. Open the transmitter cover, and route the cable through the cable gland. Connect the
wires to the screw terminals according to the wiring instructions.
3. Tighten the cable gland and close the transmitter cover.
4. Remove the yellow transport protection cap from the probe.

HMS110/112 Installation
• Medium size crosshead screwdriver (Pozidriv)
• Small slotted screwdriver for screw terminals
• Tools for cutting and stripping wires
• 19 mm open-end wrench for tightening the cable gland
Additional tools for pole installation:
• Zip ties for securing the cable to the pole
Additional tools for wall installation:
• Drill and bits
• Screws (2 pcs, Ø < 5.5 mm) and wall plugs
• Cable clips for securing the cable to the wall
1. Open the six screws that hold the transmitter cover.
2. Route the power and signal cable through the cable gland, and connect the wires to the
screw terminals according to the wiring instructions:
•Wiring Devices with Analog Output (page 14)
•Wiring Devices with Modbus Output (page 16)
For the arrangement of the screw terminals, see Component Board (page 12).
3. Adjust the length of cable between the cable gland and the terminal blocks. Make the
cable short enough to close the cover without leaving a cable loop in the transmitter.
4. Disconnect the wired screw terminal blocks by pulling them o from the component
board.

5. Pole installation mounting:
a. Use the supplied clamp and screws to mount the transmitter on a pole.
b. To prevent the transmitter from turning on the pole, tighten the set screw on the
center hole of the clamp.
6. Wall installation mounting:
a. Drill two holes for wall plugs 100 mm apart.
b. Place the wall plugs in the holes.
