Hotwire Anemometer - Transmitter
Air Velocity / Temperature / Relative Humidity

  • Hot wire anemometer transmitter
  • Cable or TO mount
  • Options for humidity and temperature
  • High sensitivity for low speeds
  • Analog Output 4-20mA or 0-10V DC
  • Variable response time for turbulence
  • Ready calibrated

The family of transmitters series HD29 ... are employed in the control of air speed in the air conditioning and ventilation systems in the pharmaceutical, museums, clean rooms, ventilation ducts, industrial sectors and households, crowded places, cafeterias, auditoriums, gymnasiums or on farms with large numbers of animals. The sensors in combination with accurate electronics consistantly produce precise and reliable measurements . The sensor for air speed is a thin film device. The probe sheath is AISI304, the filter relative humidity of 20μ wire mesh, materials that allow the use in hostile areas. There are two possible installations: in the TO version, the horizontal probe is joined to the electronics enclosure while in the TC version the probe is connected to the electronics via a cable. The probes are available in various lengths
