It has been announced that the EE8915 from E+E Elektronik meets all relevant railway standards for reliable CO2 measurement in railway vehicles. On-board sensors aim to ensure high CO2 measurement accuracy independently of temperature, altitude or weather conditions. Due to high measurement performance in harsh environment, the sensor is also suitable for demanding process and climate control.

The E+E NDIR dual wavelength infrared measuring principle is particularly insensitive to contamination and automatically compensates for ageing effects. The EE8915 thus offers long-term stability even under harsh conditions. The multi-point CO2 and temperature factory adjustment ensures high measuring accuracy over the entire temperature range from -40 to +60°C.

Due to its design, the CO2 sensor offers a unique combination of short response time and high protection class IP65 / NEMA 4. On-board sensors allow for active temperature and pressure compensation. The EE8915 therefore provides accurate CO2 readings even under changing environmental conditions.

The CO2 measured data in the range 0 to 2,000, 5,000, 10,000ppm is simultaneously available as current and voltage output. The USB service interface facilitates the configuration and adjustment. The EE8915 is available for wall or duct mount, with M12 connector or fixed cable. The robust polycarbonate enclosure remains closed during installation, which optimally protects the electronics.
