INFRARED GAS SENSOR HAVING A COMMUNICATION DEVICE AND METHOD OF COMMUNICATING CALIBRATION INFORMATION FROM AN INFRARED GAZ SENSOR

摘要

A method of communicating calibration information from an infrared gas sensor (200) includes the step of modulating infrared or visible light from an infrared energy source (230) in a manner that corresponds to calibration information to be transmitted from the sensor (200) through a transmissive section (250) in the sensor housing . Infrared energy from the infrared energy source (230) , which is within the housing of the sensor, also interacts with an analyte in a manner detectable by at least one detector (236a, 236b) within the housing.
