High frequency pressure transducers, also called dynamic pressure sensors, are a special type of pressure sensor. The response frequency of traditional pressure sensors is generally less than 1KHz, which cannot well capture and measure dynamically fast-changing pressure waveforms. But in many industrial measurements, we need to measure instantaneous data in the pressure change process. This requires the use of high frequency pressure transducers.

High frequency pressure transducers have a natural frequency as high as 1-2MHz, with a measurable bandwidth of 0-200KHz, which can well capture and record details of the dynamic pressure change process. This makes it widely used in scenarios that require measuring high-frequency pressure signals, such as:

• Explosion testing: such as pipeline explosion tests, underwater blasting tests to record the pressure waveforms generated instantaneously during explosions;
• Pump testing: testing frequent pressure changes during the pumping process;
• Hydraulic machinery testing: testing rapid pressure fluctuations caused by frequent opening and closing of hydraulic valves during hydraulic machinery operation;
• Generator testing: testing instantaneous pressure signals generated during generator operation.

These scenarios require the use of high-frequency dynamic pressure sensors with high response frequencies and short response times to complete the measurement tasks. A commonly used product type is Sino-Inst's SI-90 high-frequency dynamic pressure sensor, which uses edge thin film piezoelectric elements with a maximum response frequency of 2MHz and a measurable bandwidth of 0-200KHz, having strong dynamic response capabilities.

In summary, high frequency pressure transducers are the preferred solution to meet the high accuracy and dynamic response requirements for dynamic pressure signals in industrial automation and engineering measurement research. They are widely used in various tests and monitoring that require capturing details of transient pressure waveforms.
