ROTRONIC – TEMPERATURE MEASUREMENT IN THE HVAC INDUSTRY
Climate control in buildings is generally temperature focused, but increasingly humidity measurement is being considered essential for optimum comfort and energy use in the HVAC industry.
Temperature Measurement Applications
Air conditioning control (BMS) – low cost, low specification products are generally used in this market (+/-5%rh, +/-1°C). Installing Rotronic sensors and dataloggers provides better accuracy and long term stability.
High specification HVAC installations requiring IP65 ingress protection – swimming baths, saunas, clean manufacturing areas.
Air handling system control and to balance air distribution systems by monitoring fresh air intake.
