The 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 an easy field configuration of wet-bulb, enthalpy, and dew point outputs instead of RH in the 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.

The following models are available:

MW82, HMW82, HMW82P100, HMW83, TMW88, HMW88, HMW88D, HMW89, HMW89D, TMD82, HMD82, HMD82D, HMD83, HMD83D, HMS82, HMS82C, HMS83, HMS83C.

Dimensions

HMW82/83 RH+T and TMW82 T-only transmitters for wall-mounting.

HMS82/83 RH+T and TMS82 T-only transmitters for outdoor measurements.

Typical installation locations

• Ventilation ducts
• Walls
• Wash-down areas
• Outdoor locations

The versatile HMDW80 series includes transmitters for wall and duct mounting, IP65-classified transmitters for humid areas, and transmitters with a radiation shield for outdoor use. It also includes temperature-only transmitters and transmitters with an optional display. Calculated humidity parameters – dew point temperature, wet bulb temperature, and enthalpy – are also available.

Benefits

• Easy Installation
  HMDW80 series transmitters are optimized for easy installation. There are no loose parts, screws are retained in the enclosure, all connectors are clearly labeled, and the connectors are within easy reach. 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.
• Reliable Operation
  HMDW80 series transmitters require minimal maintenance thanks to their excellent sensor stability and high-quality materials. If necessary, the INTERCAP  sensor can be easily exchanged in the field with minimum downtime.
