Why Oxygen Sensors Are Effective In Various Field

Oxygen is one of the most required gas particles that needs accurate measurement and point of concentration. With this, a patient and different type of purposes can’t be fulfilled at any cost. Therefore, it would be the best way to come with right kind of oxygen sensor that can easily meet the industry needs.

When time comes to think about better oxygen sensor, it would be the best approach to get all these things on right way and when the oxygen is specially used in medical, it is important to know the above parameters for betterment of the patient.

How it works

The O2 sensor works like a miniature generator and produces its own voltage when it gets hot. Inside the vented cover on the end of the sensor that screws into the exhaust manifold is a zirconium ceramic bulb. The bulb is coated on the outside with a porous layer of platinum. Inside the bulb are two strips of platinum that serve as electrodes or contacts.

The outside part of the bulb is exposed to the hot gases in the exhaust while the inside of the bulb is vented internally through the sensor body to the outside atmosphere. Older style oxygen sensors actually have a small hole in the body shell so air can enter the sensor, but newer style O2 sensors "breathe" through their wire connectors and have no vent hole. It's hard to believe, but the tiny amount of space between the insulation and wire provides enough room for air to seep into the sensor.

Venting the sensor through the wires rather than with a hole in the body reduces the risk of dirt or water contamination that could foul the sensor from the inside and cause it to fail. The difference in oxygen levels between the exhaust and outside air within the sensor causes voltage to flow through the ceramic bulb.

Apart from oxygen sensors, there are also flow sensors available that deliver outstanding result just by providing the accurate measurement of flow of gas to the end user. This is the main reason; you can find a number of data is available regarding the gas and their supply not only to the industries but also to various purposes.
