Vaisala has launched two enhanced duct-mounted transmitter models.

They are designed for demanding ventilation applications in building automation systems and for light industrial applications, where accurate and stable control of relative humidity and temperature are required.

Vaisala HUMICAP Humidity and Temperature Transmitter HMD62 is optimized for monitoring relative humidity and temperature, whereas Vaisala HUMICAP Temperature Transmitter TMD62 is dedicated solely for temperature measurements.

The new HMD62 will replace the current HMD60U and HMD60Y, and the TMD62 will replace the current HMD60T.

The new HMD62 transmitter will incorporate all the calculated humidity parameters: dew point, wet bulb, enthalpy, absolute humidity, and mixing ratio. Also, the field adjustment and calibration is now convenient with the high precision trimmers or by using the Vaisala HUMICAP Hand-held Humidity and Temperature Meter HM70.

The HMD62 is also configurable on-site by using the complimentary Vaisala Insight PC Software. The HMD62 has also improved measuring accuracy, now up to ±1.5 % RH and ±0.1 °C (±0.18 °F). The newly launched transmitters are resistant to chemicals and dust, and their all-metal bodies are IP66/NEMA 4-rated.

Metal enclosure and robust mechanics support also the easy maintenance. Another new useful and time-saving feature of the new transmitters is the ability to open the product cover for adjustments without removing the unit from the duct.

The newly launched Vaisala HMD60 series products are equipped with the latest generation HUMICAP R2 composite sensors. The new sensor offers improved accuracy and unparalleled corrosion resistance even in very harsh environments.

Vaisala product manager, Lars Stormbom, said the goal was to make the best even better.

“That's why we added new features to the well-known HMD60, and made no compromises in the improved accuracy and usability,” he said.

"The combination of these new transmitters' high accuracy, long term stability and reliability makes the products ideal choice for any HVAC or building energy management application, like for example museums, cleanrooms and laboratories."

Both of the newly launched models come with a traceable calibration certificates.
