Humidity and Temperature Transmitter Series HMDW80 ±3%RH low maintenance transmitters for standard HVACThe HMDW80 series is versatile with transmitters for wall and duct mounting for measuring relative humidity and temperature in various building automation applications. These transmitters combine easy installation and reliable operation with a low requirement for maintenance. The HMDW80 Series has easy field configuration of wet-bulb, enthalpy and dew point outputs instead of RH in duct. There are IP65-classified transmitters for humid areas and sensors with a radiation shield for outdoor use. The series also includes temperature-only transmitters and transmitters with an optional display. 5-year warranty is valid for instruments purchased in 2021 and beyond.The duct mount transmitters are well suited to a variety of duct sizes, the outdoor transmitters can be mounted directly onto a wall or pole without any extra accessories, and the wall mount transmitters can be installed without the need to make holes in the transmitter enclosure.
