Hello everyone, welcome to the Star Instrument Classroom, in this issue we will talk about the selection of the measuring element of the downpressure transmitter. According to the pressure-sensitive components, pressure transmitters can be divided into micro-fusion, diffusion silicon, monocrystalline silicon, sapphire, sputtering film, etc. Micromelting: Measuring range: 0.6-1000MPa Disadvantages: poor accuracy, large temperature drift, poor stability, poor overload capacity Advantages: Durable, affordable, high upper range, impact resistance, high frequency of response Application: Workplace with low accuracy requirements. Diffusion Silicon: Measuring range: 0.1-100MPa Disadvantages: general impact resistance, general overload capacity, general temperature drift, moderate range of range Advantages: low price, mature process, good long-term stability, high precision, strong applicability, high response frequency Application: It can be applied to the site under general working conditions. Single crystal silicon: Measuring range: -0.1-7MPa Disadvantages: large range limitations, high price, large volume, not easy to install Advantages: high precision, strong overload capacity, mature process, good stability, high response frequency, small temperature drift Application: Petrochemical and other working conditions. Sapphire: Measuring range: 0.004-260MPa Disadvantages: high price, average insulation Advantages: mature process, good long-term stability, high precision, high temperature resistance, low temperature drift Application: aerospace and other fields. Sputtering films: Measuring range: 0.6-150MPa Disadvantages: poor overload capacity, large range limitations, general insulation Advantages: durable, affordable, impact resistant, high response frequency Application: aerospace, construction machinery and other fields.
