The E+E EE85 CO2 Switch is optimized for building automation as well as for process control applications. It measures CO2 concentration based on the Non-Dispersive Infrared (NDIR) technology. A patented auto-calibration procedure compensates for the aging of the infrared source and leads to outstanding long-term stability.
The EE85 is available with measuring ranges of 0 to 2000, 0 to 5000 or 0 to 10000 ppm and with two probe lengths. The switch threshold and hysteresis can be set with potentiometers on the printed circuit board.
The air from the duct flows through the probe into the EE85 enclosure and back into the duct. Inside the enclosure the air diffuses through a membrane into the CO2 sensing cell. As there is no flow through the sensing cell, this is very well protected against dust.
Applications for the EE85 include:
This product can be used in the following applications:
