HMD60 Series Humidity andTemperature Transmitters - 1

HMD60 Series Humidity and Temperature Transmitters For Demanding HVAC and Light Industrial Applications • Measurement accuracy up to ±1.5 %RH and ±0.1 °C (±0.18 °F) • 4 ... 20 mA analog outputs: HMD62 (RH and T) and TMD62 (T-only) • 0 ... 10 V analog outputs: HMD65 (RH and T) • BACnet MS/TP and Modbus RTU: HMD65 • All common humidity parameters available, including RH, dew point, enthalpy, and wet bulb temperature • Resistant to chemicals and dust • IP66-rated body • Traceable calibration certificate • Easy field adjustment and output configuration with quick access to electronics also when installed • Compatible with Vaisala Insight PC software Analog or Digital Output with 3 Transmitter Options HMD60 series transmitter options: • HMD62: RH and T measurement, 4 ... 20 mA analog output • TMD62: T-only transmitter, 4 ... 20 mA analog output • HMD65: RH and T measurement, 0 ... 10 V analog output, Modbus RTU, and BACnet MS/TP Robust Design, Stability, and Reliability The all-metal body is suitable for building sites and industrial settings. HMD60 series transmitters provide state-of-the-art stability and environmental resistance, thanks to the Vaisala HUMICAP® R2 sensor. For applications where hydrogen peroxide disinfection is used, the HUMICAP® 180V catalytic sensor option provides improved stability during H2O2 exposure. Traceable Accuracy HMD60 series transmitters are always delivered with a traceable (ISO9001) calibration certificate. Upon request, accredited (ISO17025) calibration certificates can also be provided. Field Configurable Outputs The analog HMD62 and TMD62 transmitter models use floating 4 ... 20 mA loop powered outputs. The HMD65 model has two 0 . 10 V outputs in addition to BACnet MS/TP and Modbus RTU interfaces (RS-485). The analog outputs are field configurable with easy humidity parameter selection using DIP switches. For special scaling and other additional configuration and adjustment options, you can use the convenient Vaisala Insight PC software for Windows® (see www.vaisala.com/insight). When required, HMD60 series transmitters can also be intuitively field adjusted using trimmers or with the Vaisala HM70 handhel
