GENERAL DESCRIPTION
The HD 2021T series allows conversion of photometric and radiometric quantities as illuminance (Lux) and irradiance (W/m2) - across, UVA, UVB, UVC spectral regions and 400 ÷1000nm band - into a 0 ÷10 voltage signal. The voltage output 0 ÷ 10 V ( 0 ÷ 1 V, 0 ÷ 5V, 4 ÷ 20mA on request for substantial orders) comes factory
set calibrated to the full scale range specified at the time of order. HD 2012T transmitters wide range of applications include:
• Measurement of illumimance (HD 2021T ) in offices and laboratories, manufacturing plants and production areas, commercial sites, theatres, museums, sports lighting, roadway lighting, tunnels and nursery-gardening systems.
• Measurement of solar irradiance, within 400nm ÷ 1000nm spectral band (HD2021T.1).
• Monitoring tanning lamps irradiance within UVA (HD 2021T.2) and UVB (HD2021T.3)
spectral regions, as well as efficiency control in filters for high pressure UV lamps.
• Efficiency control in UV lamps used in water purification plants, where UVC
(HD2021T.4) band irradiance needs to be constantly monitored.
HD2021T transmitters can be installed either for indoor or outdoor applications
(Protection: IP66). In case of extremely intense light sources measuring, the transmitter sensitivity can be reduced upon request. The HD 2021T series employs
filters and photodiodes especially studied to adjust spectral response to a specific region of interest.
