Description
The sensor has field selectable NO2 ranges of 0 to 2.5, 0 to 5, 0 to 7.5 and 0 to 10 ppm. It also has field selectable outputs of 0 to 5, 1 to 5, 0 to 10 and 2 to 10 VDC as well as a 3-wire 4 to 20 mA output. The LCD is backlight for 10 seconds after a button push.
Two independent SPDT alarm contacts switch at 5 field-selectable NO2 concentrations from 1 to 10 ppm. An alarm timer holds the output relays on for a fixed time after the NO2 level has fallen below 80% of setpoint to allow additional fan time to ensure the NO2 has been purged. The field replaceable sensor element lasts approximately 7 years and is self-tested daily.
