The use of hydrogen sensors can quickly and sensitively collect the hydrogen concentration in the use environment, and the measurement accuracy is high, up to ±3% FS, and the repeatability can be up to within 2%.
The equipment adopts a unique compensation algorithm and multi-stage standard gas calibration, which has many characteristics such as strong anti-interference ability, high stability and long service life.
The concentration of hydrogen released in different environments is different, so the range of measuring hydrogen concentration is 0~1000ppm, 0~40000ppm, etc.
Hydrogen Sensor Working Principle
Common Hydrogen sensor working principles include conductive type, thermoelectric type, catalytic combustion type and electrochemical type.
When the device adsorbs hydrogen, the hydrogen releases electrons as a donor and combines with the oxygen ions in the chemical adsorption layer, so the carrier concentration changes. Based on the functional relationship between the change value and the hydrogen volume fraction, the real-time concentration of hydrogen is calculated. This is how an electrical conductor hydrogen transmitter works.
When the sensitive element is exposed to an environment containing hydrogen, under the action of the catalytic metal, the hydrogen and oxygen react to generate water vapor and release heat. Therefore, the end where the catalytic metal is deposited has a high temperature, which is the hot end, and the end where the catalytic metal is not deposited has a low temperature. As the cold end, due to the thermoelectric power generation effect (Seebeck effect) of the thermoelectric material, the temperature difference between the hot end and the cold end is converted into a temperature difference potential and output in the form of an electrical signal, thereby realizing the detection of hydrogen. This is It is called a thermoelectric hydrogen transmitter.
The electrochemical hydrogen sensor utilizes the active chemical properties of hydrogen, which has reducing or oxidizing properties, and is a precision monitoring device. During the process of participating in chemical reactions, electrons are released or absorbed, and a large number of electrons form a current. The size of the current is proportional to the gas concentration. By measuring the size of the current, the real-time concentration of hydrogen can be measured.
