The transmitters of the HD37… series are used in air quality control by measuring CO2 (Carbon Dioxide) in the ventilation systems. This allows you to vary the number of air change per hour according to ASHRAE and IMC norms.
The purpose is twofold: to have a good air quality in the presence of people and to save energy, increasing or decreasing parts of air per hour, depending on the air quality set. The use is for environments where there is overcrowding of people, discontinuous crowding, cafeterias, auditoriums, schools, hospitals, greenhouses, livestock breeding, etc.
Model HD377B-TV.1 is a vertically mounted transmitter with a range of 0-5000ppm CO2 and 0…+50 °C Temperature range.
Output 4-20mA
