While pellistor type LEL sensors usually stabilize completely within 6 - 8 minutes, electrochemical sensors that have been exposed to certain interfering contaminants can sometimes take an hour or longer to clear completely. For instance, CO sensors are equipped with an internal filter to prevent or limit the sensor's response to VOC contaminants.

Chapter 2 Electrochemical Sensors

Electrochemical sensors operate by reacting with the gas of interest and producing an elec-trical signal proportional to the gas concen-tration. A typical electrochemical sensor con-sists of a sensing electrode (or working elec-trode), and a counter electrode separated by a thin layer of electrolyte, Figure 3. Gas that comes in contact with the sensor

Introduction to Electrochemical (EC) Gas Sensors

Working Electrode: CO + H 2O → CO 2+ 2H+ +2e-Counter Electrode: ½O 2 + 2H+ + 2e-→ H 2O Overall: CO + ½O 2 → CO 2 Because the electrodes have a finite catalytic activity (which can change with time and temperature) it is necessary to limit the rate of diffusion of target gas into the sensor (using a barrier) to ensure the gas is efficiently reacted.

30-10-2014· A CO sensor which has a positive response to H 2 at a rate of 60%. Therefore, if the CO sensor saw 200ppm of H 2 then the CO sensor will show around 120ppm ( 60% of 200ppm). Negative response A negative response is when sensors produce a reduced response to the target gas if also exposed to a gas that causes a negative response.
