Introduction to HMD60 Series
The duct mounted HMD60 HUMICAPâHumidity and Temperature Transmitters are designed
for monitoring humidity and temperature in demanding HVAC and light industrial applications.
HMD60 series transmitters provide stable, reliable, and highly accurate (up to ±1.5 %RH and
±0.1 °C (0.18 °F) measurements, and are resistant to chemicals and dust.
HMD60 series transmitter options include two analog output models: HMD62 for measuring
both humidity and temperature, and TMD62 for temperature measurements. Both HMD62 and
TMD62 use 4 ... 20 mA loop powered current output.
Thanks to easy access to electronics also when the transmitter is installed to a duct,
configuration and adjustment can be carried out quickly and conveniently. Available
configuration and adjustment interface options range from physical trimmers and DIP switches
on the transmitter's circuit board to Vaisala Insight PC software for Windowsâ.
HMD60 Series Basic Features and Options
• Two analog transmitter model options:
• HMD62 for humidity and temperature measurement
• TMD62 for temperature measurement
• Humidity parameters available as output options in HMD62: RH, Td, Tdf, A, X, Tw, H
• Default temperature analog output scale: -20 … +80 °C (-4 … +176 °F)
• Analog output: 4 ... 20 mA, loop powered
• HMD62: 2 analog output channels for humidity and temperature
measurements
• TMD62: 1 analog output channel for temperature measurement
• Power supply input: 10 ... 35 VDC / 20 ... 35 VDC
•Configuration and adjustment options:
• RH and T measurement field adjustment with trimmers
• Humidity output parameter selection with DIP switches (HMD62)
• Field adjustment with MI70 hand-held indicator
•Configuration and adjustment with Vaisala Insight PC software

Figure 3 Duct Installation Overview
1Make sure there is a minimum clearance of 5 m (16.5 ft) between the probe and any
possible humidifier.
2When installing the probe, drill a second hole approximately 30 cm (12 in) from the
HMD60 probe's installation hole, towards the direction of the air flow, and plug it with a
removable seal. This second hole is intended for later use in reference measurement when
calibrating or adjusting the transmitter.
3Check that the duct diameter is suitable for the 250 mm (9.85 in) probe body. Ideally, the
sensor should be installed in the middle of the duct.
4Maximum air flow speed: 50 m/s (with sintered filter).
5Avoid installing the probe in dead legs. Supersaturation can occur in areas where there is
no air flow.
6Do not install the probe in a downward angle. Condensation can travel to the sensor along
the probe body if the probe points down.
7Install the probe in a 90° angle so that the sensor is placed as close to the middle of the
duct as possible.
Avoid installing in a location where condensation can fall on the
sensor inside the duct.
CAUTION!

Installing into Duct
• Medium size crosshead screwdriver for mounting screws and lid screws.
• Small slotted screwdriver for screw terminals.
• Drill with 3.5 mm (0.14 in) and 13 … 15 mm (0.51 … 0.59 in) bits for making the
installation holes.
• Tools for cutting and stripping wires.

Figure 4 Drilling and Mounting Screws
1. Select an installation location for the transmitter on the duct surface and drill a
Ø 13 … 15 mm (0.51 … 0.59 in) hole for inserting the probe.
2. Push the probe through the hole on the duct until the transmitter body meets the duct.
3. Attach the transmitter body to the duct with 2 Ø 3.5 mm (0.14 in) screws.
Check that the insulation ring sits tightly over the installation hole. If the duct
has a negative pressure, external air can be drawn into the duct and aect
the measurement if the installation hole is not sealed tightly.
4. Optional: Drill a second hole for reference measurements approximately 30 cm (12 in)
from the HMD60 probe's installation hole, towards the direction of the air flow.
5. Open the 2 captive screws on the transmitter body and remove the lid.
6. Attach the input/output wiring to the screw terminals on the transmitter component
board. See Wiring (page 11). Tighten cable glands firmly after wiring.
7. Check that the DIP switches and trimmers are in the correct position. See DIP Switch
Output Selection (HMD62) (page 15) and Trimmers (page 14).
8. Close the transmitter lid and switch on the transmitter's power supply input.
