What is a potentiometric sensor?
Potentiometric sensor is a type of chemical sensor used in a wide range of industrial processes to determine the volume presence of a compound based on the detection of ionic atoms or molecules in a compound that bear an electric charge. The sensor does not require current flow, but only that the compound itself, whether liquid or gas, passes between the electrodes of the sensor device. One of the most common potentiometric sensor units produced since 2011 is the oxygen sensor incorporated into cars, but there are many other uses for this technology. The voltage difference occurs when a solid electrolyte compound between the two electrodes obtains an electric charge as a liquid or gas in the form of an ion wire. The level of charge is used to determine the amount of ions present and this value can then be compared to the expected weight values and activates the controls to maintain the desired equilibrium state.
oxygen sensors, also known as lambda probe, have been included in cars manufactured in the United States since 1980 as a commonly used potentiometic sensor and are present to ensure that vehicles meet control standards in certain countries and optimize fuel efficiency. They work by measuring the amount of ionized oxygen, which is present in the exhaust current while the engine is running. The microprocessors in the vehicle then take this value and compare it to the optimum gases of gases. Where there is a change in the output, control of the computer can adjust the air/fuel mixture and the timing of the ignition on the Ensure that there is more full fuel burning and reduced pollution. All types of vehicles, whether powered by diesel fuel, petrol, ethanol or combinations of such fuels, use these sensors and more modern versions of the device measures the range of different gas gas except oxygen.
Another bondThe living of the potentiometric sensor involves analysis of trace gas in analytical chemistry except for trillion parts and to determine the polar amounts of solvents such as water, alcohol and other chemicals used to create precise industrial solution formulas. Since 2011, research has also led to the use of a potentiometric sensor in pharmaceutical analysis. They are used to detect lead and surface active substances in wastewater currents from the treatment plant and for many other reasons in agricultural and medical areas, as well as for inspection of environmental pollution in a number of industries. Potentiometric sensor structures of ionic membranes used to detect heavy metals, drought as lead or determining the level of pH soil samples in 15 seconds or less and be repeatedly used for up to four months without degradation.
