Catalog excerpts

YOUR PARTNER IN SENSOR TECHNOLOGY EE82 CO2 Switch for harsh environment EE82 is optimized for harsh climate control applications such as life stock barns or storage of fruit and vegetables. The robust enclosure has been tailored for best protection of the CO2 sensing cell. The air diffuses first through the filter on the front cover into the instrument enclosure and then through a second membrane filter into the CO2 sensing cell. As there is no flow through the sensing cell, this is very well protected against pollution. The CO2 measurement is 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. EE82 is available with measuring ranges of 0...2000, 0...5000 or 0...10000ppm. The switch threshold and hysteresis can be set with potentiometers on the printed circuit board. The EE82 with snap-in mounting flange and M12 electrical connector allows for easiest installation, replacement or removal of the device during site cleaning and sterilizing operation.
