High Frequency
Dynamic pressure measurement requires pressure sensors with a fast response speed that can keep up with transient signals. Ensure that the sensor’s resonant frequency is significantly higher than the frequency of the signal you are measuring. Conventional pressure sensors typically have a maximum frequency of only 2 kHz to 3 kHz. The SI-90 Dynamic-High Frequency Pressure Sensor has a response frequency of 20 kHz to 200 kHz.
High Speed – Rise Time
This is the most critical factor. To capture fast transient signals, you need a pressure sensor with a fast response speed. We are referring to rise times in the microsecond range. If the sensor responds too slowly, it will miss the peak amplitude of the pressure spike.

Sino-Inst is a manufacturer of Dynamic-High Frequency Pressure Sensor. High-frequency pressure sensors are also called high-frequency dynamic pressure sensors, dynamic pressure sensors, and pulsating pressure sensors. Typically used for rapidly changing pressure measurements. For example, pressure detection at the moment of explosion, frequent reciprocating pressure detection, etc.
The high-frequency pressure transmitter is a high-frequency analog pressure transmitter. A piezoresistive pressure sensor with a stainless steel diaphragm in flush diaphragm construction as signal measuring element. The supporting dedicated high-frequency response signal processing circuit converts the signal of the measuring element into a standard current or voltage output signal. It is used in the measurement of dynamic pressure in engine test equipment and the measurement occasions with high response frequency, such as explosion waves.
