- UL-V0 flammability rating
- Output parameters: relative humidity and temperature with optional dew point temperature, wet bulb temperature and enthalpy parameters Vaisala HMDW80 Series INTERCAPâ Humidity and Temperature Transmitters measure relative humidity and temperature in various building automation applications. HMDW80 series transmitters combine easy installation and reliable operation with a low requirement for maintenance. 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. 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 INTERCAPâ sensor can be easily exchanged in the field with minimum downtime.
