subject: Industrial Oxygen Sensors And Pressure Sensors [print this page] There are different technologies used to measure oxygen such as zirconia, infrared, ultrasonic, laser and electrochemical. These technologies have their own pros and cons.
Industrial oxygen sensors have many benefits. They have long life ability due to their external and internal rugged stainless steel construction. They can be used directly in high temperatures and high pressure environments and can also be operated by simple, low cost electronics.
The zirconia oxygen sensor uses a solid-state electrochemical fuel cell called a Nernst cell. There is a variety of accurate, highly reliable and robust range of zirconia oxygen sensor available on the market with different mounting and housing options depending on the application.
Many processes use zirconia oxygen sensor for monitoring and control. Solid-state sensors are uses in a number of applications, including control of air-to-fuel ratio in combustion and control of atmosphere in materials processing. Do not use SST Sensing industrial oxygen sensors with silicon. Like any other zirconia oxygen sensor, they are damaged by the presence of silicone.
A pressure sensor measures mainly the pressure of liquids or gases. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical. Pressure sensors can vary drastically in technology, design, performance, application suitability and cost.
Pressure sensors are commonly used to monitor the pressure of fluids engines, fluids in pipes or in hydraulics. To measure the pressure of gases or solids, specialized sensors are used. A typical pressure sensor is around a cubic inch; however some may considerably smaller in size.
pressure sensors are categorised in terms of the type of pressure they measure, temperature ranges of operation and the pressure ranges they measure. Pressure sensors are named regarding their use, but the same technology can be used under different names.
The different types of pressure sensors include gauge pressure sensor which measures pressure by reference to the ambient atmospheric pressure, absolute pressure sensor which measures absolute pressure using a vacuum as a reference point, and differential pressure sensor which measure the pressure difference between two contacts.
