2. Product Overview

2.1 Introduction to HMD60 Series

The duct mounted HMD60 HUMICAPâ Humidity 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.

Table 3 (page 6), you can configure the scaling by connecting the transmitter to Vaisala Insight
PC software (requires Vaisala USB cable 219690).
2.4

 Connectivity to Vaisala Insight Software

The transmitter can be connected to Vaisala Insight software using a Vaisala USB cable (order code 219690). With the Insight software, you can:
• See device information and status.

2.5.4 Trimmers

Figure 5 Component Board Adjustment Trimmer
1 Use a Phillips head screwdriver (PH0)
to rotate the RH or T adjustment trimmer. To increase the measurement output value, rotate the trimmer clockwise. To decrease, rotate counterclockwise. Note that there is a slight delay before the measurement output changes after rotating the trimmer.
You can adjust the transmitter's RH or T measurement output with the trimmers on the component board. During trimmer adjustment, the output of the transmitter is corrected using the trimmers until the output matches the known value of a reference.
Figure 6 RH and T Trimmer Adjustment Ranges (Indicative)
You can only calibrate the relative humidity measurement (RH) and temperature measurement (T). Other parameters (available for HMD62) are calculated internally based on RH and T. Check that the output selection DIP switch is set to RH when making adjustments with the physical trimmer; when using the Insight PC software, set all DIP switches to the OFF position.
CAUTION!
restore the factory settings, always return the physical trimmer to the middle position before starting. When you make an adjustment with Insight, the
10
position in which the trimmer is at that point is set as the ±0 point.

RH Relative humidity Td Dew point temperature Tdf Dew point/frost point temperature A Absolute humidity X Mixing ratio Tw Wet-bulb temperature H Enthalpy
You can change the humidity parameter that is output on the RH channel of HMD65 with the DIP switches on the component board. Select the parameter you want the transmitter to output by sliding the parameter's DIP switch to the right (ON). In the example in Figure 7
(page 11), the selected output parameter is dew point/frost point temperature (Tdf). Keep the
other DIP switches in the OFF position (left).
The selected parameter uses the default scaling shown in Table 4 (page 11).

CAUTION!
Note that the humidity output parameter selected with the DIP switches on the transmitter component board will be used instead of the parameter selected with Insight. When using Insight to configure the output, set all humidity parameter selection DIP switches on the transmitter component board to the OFF position (left) to ensure they do not cause a conflict with the Insight settings.
11
HMD65 User Guide M212243EN-A
If you use Insight to set both analog output channels to output T measurement, the humidity parameter DIP switches do not have an eect on the output.

2.6 Filtering Factor

If the measuring environment produces occasional exceptionally high or low readings that need to be averaged out in the output, you can apply a filtering factor to the RH or T output (filtering factor range: 0.001 … 1.000). The filtering factor defines the speed at which the latest measurement is integrated into the transmitter's output. By default, the filtering factor is set to
0.500, which means that the displayed output is a 50%+50% combination of the previous measurement and the most recent measurement. To show the latest measurement directly in the output, set the filtering factor to 1.000 (no filtering).
The following formula is used when calculating the output:
output = [(new (unfiltered) measurement × filtering factor) + (previous output × (1.0 - filtering factor))]
The filtering factor can be configured with the Insight PC software.
More Information
Setting Filtering Factor with Insight (page 25)
2.7

 Environmental Compensation

By default, the pressure value used in HMD65 measurement calculation is 1013.2 hPa. If the pressure of your measurement environment diers from this, you can configure the transmitter's pressure compensation value with the Insight PC software.

Figure 9 Duct Installation Overview
Make sure there is a minimum clearance of 5 m (16.5 ft) between the probe body and any
1
possible humidifier. Avoid installing in a location where condensation can fall on the sensor inside the duct.
2 When 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.
3 Check that the duct diameter is suitable for the probe body (see Transmitter Dimensions
(page 13)). Ideally, the sensor (probe head) should be installed in the middle of the duct. 4 Maximum air flow speed: 50 m/s (with sintered filter). 5 Avoid installing the transmitter in dead legs. Supersaturation can occur in areas where
there is no air flow.
6 Do not install the probe in a downward angle. Condensation can travel to the sensor along
the probe body if the probe points down.
7 Install the probe in a 90° angle so that the sensor is placed as close to the middle of the
duct as possible.

• Tools for cutting and stripping wires.
Chapter 3 – Installation
Figure 10 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 9 (page 14).
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 16). Tighten cable glands firmly after wiring.
7. Check that the DIP switches and trimmers are in the correct position. See Transmitter
Board (page 9) for more information on DIP switches and trimmers.
