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 HUMICAPâ R2 sensor. For applications where hydrogen peroxide disinfection is used, the HUMICAPâ 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 Windowsâ (see www.vaisala.com/insight). When required, HMD60 series transmitters can also be intuitively field adjusted using trimmers or with the Vaisala HM70 handheld meter.
