2. Product Overview
2.1 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.
2.2 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 °C)
• 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

Changing Measurement Parameter Scaling
If your application requires an analog output scaling that diers from the defaults shown in
Table 3 (page 6) and Table 4 (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:
• Calibrate and adjust the measurement.
• See device information and status.
• See real-time measurement.
•Configure output parameters and scaling.
