transmitterFor precise measurement of CO2 concentrations and temperatures in HVAC applications, an additional passive temperature measurement function has been added to the EE85 CO2 transmitter. CO2 and temperature measurement in a single device cuts installation costs for sensors, said the company. The CO2 measurement of the EE85 is carried out using infrared technology (NDIR). The air to be monitored is conveyed to the measurement cell in the housing by means of convection via the measuring head and a 12-mm pipe. The exchange of gas with the measurement cell is performed by diffusion via a diaphragm. In this way, the gas in the measurement cell circulates in a closed system. This prevents any soiling of the optical measurement path and any associated inaccuracies in the measurements. The temperature sensor is installed directly in the tip of the measurement sensor and optimally protected against soiling by a diaphragm filter. The passive temperature sensor signal is available at the connection terminals in the housing and can be connected directly to the majority of control devices. The measuring ranges 0-2,000, 0-5,000, 0-10,000 ppm are available. The temperature range is -20 to 60°C. The compact housing enables easy installation directly at the ventilation duct using a mounting flange. The patented auto-calibrate function compensates for any aging effects (even if there is no fresh air supply) and ensures long-term stability.
