As a high-frequency pressure sensor, it possesses extremely strong responsiveness. This high-frequency pressure sensor is small in size, lightweight, and cost-effective, making it widely used in various fields.
I. Introduction to High-Frequency Pressure Sensor Products
This series of pressure sensors and transmitters are designed to meet users' specific requirements in terms of response frequency, shape, and operating temperature. Based on their response frequency characteristics, they are defined as miniature probe-type pressure sensors, pancake-type pressure sensors, etc.; based on their temperature resistance characteristics, they are defined as medium- and high-temperature pressure sensors, etc. Because these products need to meet multiple user requirements, the transmitters often adopt a split-type structure.
II. Application Scope of High-Frequency Pressure Sensors
Modern instruments used in scientific experiments such as military engineering, chemical explosion testing, oil exploration and production testing, materials mechanics, civil engineering, rock and soil mechanics, trauma medicine, and hydraulic power machinery testing require high-frequency pressure waveforms and amplitudes that can be measured without distortion, as well as dynamic pressure with rapid and steep effective values. This necessitates the use of pressure sensors with inherent frequencies, short rise times, and wide bandwidths to ensure excellent response and sufficient accuracy of dynamic pressure. The design and development of this series of products utilizes micromachining technology to achieve an effective small size and high inherent frequency for integrated silicon diaphragms, possessing excellent mechanical properties and better overall performance of piezoelectric dynamic pressure sensors, known as dynamic pressure testing of piezoelectric pressure sensors.
III. Design and Application of High-Frequency Pressure Sensors
High-frequency pressure sensors are an important component of pressure detection systems. They consist of various pressure-sensitive elements that convert the pressure signal to be measured into an easily measurable electrical signal as an output. This output is then used to display the pressure value on a display instrument or for control and alarm purposes.
There are many types of high-frequency pressure sensors, such as piezoresistive pressure sensors, strain gauge pressure sensors, piezoelectric pressure sensors, capacitive pressure sensors, piezomagnetic pressure sensors, resonant pressure sensors, differential transformer pressure sensors, and fiber optic pressure sensors.
