CO2 & Temperature Transmitter
CO2 & Temperature Transmitter

E+E Elektronik has added an additional passive temperature measurement function to its EE85 CO2 transmitter for precise measurement of CO2 concentrations and temperatures in HVAC applications. Enclosed in a compact housing that enables easy installation directly at the ventilation duct using a mounting flange, the combined CO2 temperature transmitter is ideally suited for applications in the fields of building management and demand controlled ventilation. Carrying out its measurements using IR technology (NDIR), it comes with a auto-calibrate function that compensates for any ageing effects (even if there is no fresh air supply) and ensures excellent long-term stability. 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 transmitter is available with 0-2000/5000/10000 ppm as well as -20 to 60°C measurement range.
