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 the HMD62 and TMD62 analog output transmitters

with loop powered 4 … 20 mA current output, and the analog and digital output transmitter

HMD65 with analog voltage output (0 … 10 V) and digital Modbus RTU and Bacnet output

(RS-485).

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 Modbus, BACnet, and Vaisala Insight PC software for

Windowsâ.

HMD65 Basic Features and Options

• Humidity and temperature measurement:

• available humidity parameters: RH, Td, Tdf, A, X, Tw, H

• T measurement in °C or °F

• Analog output: 2 analog 0 … 10 V output channels for humidity and temperature

measurements

• Digital output (RS-485): Modbus RTU and BACnet MS/TP

• Power supply input: 15 … 35 VDC / 16 … 24 VAC

•Conﬁguration and adjustment options:

• RH and T measurement ﬁeld adjustment with trimmers

• Humidity output parameter selection and Modbus/BACnet serial setting conﬁguration

with DIP switches

•Conﬁguration and adjustment with Vaisala Insight PC software

•Conﬁguration with Modbus and BACnet

• Field adjustment with MI70 hand-held indicator

Output Parameter Scaling

• Default temperature analog output scale: -20 … +80 °C (-4 … +176 °F)

• Default scaling for humidity parameters: see Table 2 (page 15).

• To change the default scaling of an analog output parameter, use Vaisala Insight PC

software. See the instructions in HMD65 User Guide.

More Information

For more detailed instructions for installing, conﬁguring, and maintaining the HMD60 series

transmitters, see HMD62 and TMD62 User Guide in English M212016EN and HMD65 User Guide

Figure 3 Duct Installation Overview

1Make sure there is a minimum clearance of 5 m (16.5 ft) between the probe body and any

possible humidiﬁer.

2When installing the transmitter, drill a second hole approximately 30 cm (12 in) from the

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 with another device

when calibrating or adjusting the transmitter.

3Check that the duct diameter is suitable for the probe body (see Transmitter Dimensions

(page 7)). Ideally, the sensor (probe head) should be installed in the middle of the duct.

4Maximum air ﬂow speed: 50 m/s (with sintered ﬁlter).

5Avoid installing the transmitter 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 transmitter installation hole. See Figure 3 (page 8).

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 Transmitter

Board (page 10) for more information on DIP switches and trimmers.

8. Close the transmitter lid and switch on the transmitter's power supply input.
