01Accuracy of pressure sensors in the WIKA sample In the WIKA catalog, the accuracy of the pressure transmitter is marked as follows: Yesterday a student asked, what does the suffix FS mean for 0.125%FS? Let’s talk about this issue today. 02The meaning of full scale accuracy and reading accuracy Reading accuracy: It is the error…
Ordinary solenoid valves are the basis of all solenoid valves, including proportional valves . Since the force value of the solenoid proportional valve is proportional to the current , for a certain current value (usually measured by the rated current), it can be regarded as an equivalent solenoid valve corresponding to its current. The first…

The measurement of oxygen content in the oxidation process of chemical production and the selection of oxygen analyzers depend on the reaction steps used. Air (such as for the production of maleic anhydride or phthalic acid), oxygen-enriched air (such as for the production of acrylonitrile) or pure oxygen gas (such as for the production of…
As the name implies , an anemometer is an instrument for measuring air velocity. It uses a high-performance wind speed sensor and a complete microcomputer detection and control instrument, which can simultaneously monitor and display the measured wind speed changes. The principle is to place a thin metal wire in a fluid, pass an electric…
With the rapid development of industrialization, the problem of waste gas emissions from fixed pollution sources has become increasingly prominent, causing serious impacts on the environment and human health. The emergence and development of waste gas monitoring technology has provided strong support for the effective control and reduction of waste gas emissions. By continuously monitoring…
