What are oxygen sensors made of?
The sensor is made of Zirconium Oxide (ZrO2), a chemical compound used to form the sensor’s thermal-driven electrochemical fuel cell. Two Platinum (Pt) electrodes are placed on the ZrO2 to provide a connection for output voltage to a control module.
Why is the oxygen sensor reading higher than the gas sensor?
This concentration certainly is high enough to change the thermal conductivity of the atmosphere and produce a change on the LEL sensor. In this situation, you also should note that because of the high level of CO2, the oxygen sensor probably was reading higher than the actual gas concentration due to interference with that sensor.
How does a gas sensor work in a portable gas detector?
That is the question. Most sensors intended for use in portable gas monitoring instruments are designed to operate in the passive mode. These designs are such that gas in air diffuses through normal air currents into openings on the face of the sensor and accumulates on and reacts with the sensor’s working electrode.
What happens when a sulfur dioxide sensor is exposed to NO2?
If a sulfur dioxide (SO2) sensor, which typically has a -100 percent cross interference to nitrogen dioxide (NO2) is exposed to 2 PPM NO2, the resultant SO2 reading on your instrument will be -2 PPM. Does this mean that you should avoid using sensors that have negative cross interferences to each other in the same instrument?
When was gas sensor cross interference in Phoenix?
Gas sensor cross interferences have been the topic of many questions over the years. In 2011, firefighters in Phoenix, Ariz., were called to an incident at a fast food restaurant after a worker had collapsed walking up the stairs from the basement.
What happens if you have an oxygen sensor problem?
Mercedes oxygen sensor related problems can lead to decreased performance and snowball into bigger issues with the car. Hence in order to understand any Mercedes oxygen sensor problems faced, seek the help and insights of the Experts.
Where is the oxygen sensor on a Mercedes?
The heated Mercedes oxygen sensor which is located to the rear of the catalytic converter produces an output signal. Of which is relative to the oxygen storage capacity of the catalytic converter. The heater oxygen sensor is generally less active than the signal produced by the front Mercedes oxygen sensor.
What does error code 17 on Mercedes oxygen sensor mean?
The error code 17 on the Mercedes oxygen sensor generally indicates a communication fault between the sensor and module. It means there is no signal being sent from the Mercedes oxygen sensor. This sensor can be found mounted on the exhaust system after header and before the muffler.
