Pressure Sensor Calibration Case Share. The customer purchased a batch of high frequency dynamic pressure sensors from our company. According to customer requirements, the accuracy of our pressure sensor is ±0.25% FS.
After the pressure sensor was produced, it was delivered to a third-party inspection company. The accuracy of the high-frequency dynamic pressure sensor was verified. As a result of the verification, the accuracy of our high-frequency dynamic pressure sensors has reached ±0.20% FS, and a calibration certificate is attached.
About high frequency dynamic pressure sensor
The customer purchased our SI-90 high frequency dynamic pressure sensor.
SI-90 High Frequency Dynamic Pressure Senosr
The use of micro-machining technology makes the effective size of integrated silicon chips small, high natural frequency, and excellent elastic properties. Comprehensive performance is better than piezoelectric dynamic pressure sensors. It is the first choice for dynamic pressure measurement.
