Hello everyone, welcome to the astrometer class, in this issue we will talk about the selection of the measuring element of the downforce transmitter. According to the pressure sensitive components, pressure transmitters can be divided into strain gauge, ceramic piezoresistive, ceramic capacitive, metal capacitive, etc. Strain Gauge: Measuring range: 0.6-1000MPa Disadvantages: poor accuracy, large temperature drift, poor stability, poor overload capacity, low response frequency Advantages: durable, affordable, high upper range, impact resistance, mature process Application: Workplace with low accuracy requirements. Ceramic piezoresistive: Measuring range: 0.05-60MPa Disadvantages: average accuracy, poor overload capacity, large annual drift, large range limitations, poor seismic resistance Advantages: corrosion resistance, wear resistance, low price, high response frequency Application: chemical industry and other corrosive working conditions. Ceramic capacitive: Measuring range: -0.1-7MPa Disadvantages: large range limitations, high price, poor load capacity Advantages: high precision, corrosion resistance, wear resistance, strong overload capacity, high response frequency, good stability Application: medical and other health fields. Metal Capacitive Type: Measuring range: -0.1-20MPa Disadvantages: large range limitations, high price, large size, not easy to install Advantages: high precision, strong overload capacity, mature process, good stability Application: petrochemical industry and other fields.
