At Xi'an Qintai Automotive Emission Technology Co. Ltd., our High frequency pressure transducer represents cutting-edge engineering in dynamic pressure measurement. Established in 2001 as a national high-tech enterprise, we've developed specialized sensors utilizing high-stiffness sensing elements with natural frequencies ranging from 100 kHz to over 1 MHz. Our transducers capture rapid pressure fluctuations on microsecond scales, solving critical signal aliasing issues in demanding applications.
With an annual production capacity exceeding two million sensors and 58 invention patents, we deliver enterprise-grade reliability you can trust. Our independent R&D team of 86 technicians continuously innovates to meet your most challenging measurement requirements.

Our sensors are designed particularly for applications where standard weight transmitters essentially cannot perform. They exceed expectations at capturing high-speed marvels like stun waves, combustion insecurities, and water powered surges.
The mystery lies in our progressed detecting innovation. We utilize micro-machined silicon-on-insulator (SOI) films and piezoelectric precious stones that react immediately to weight changes. This dispenses with the mechanical slack that causes conventional sensors to miss basic data.
Your operations request accuracy. Whether you're observing diesel motor combustion elements or analyzing transitory weight occasions, our transducers provide exact, real-time information when milliseconds matter.

What is a product?
A item is a specialized sensor planned to capture fast, temporal weight changes happening on microsecond scales. Not at all like standard weight sensors, these gadgets utilize high-stiffness detecting components to accomplish normal frequencies from 100 kHz to over 1 MHz, making them fundamental for observing stun waves, combustion occasions, and water powered surges.
How does it contrast from standard weight transmitters?
Standard weight transmitters degree inactive or gradually changing weights. Our high-frequency models react right away to energetic weight occasions without mechanical slack or flag aliasing. This makes them perfect for applications where conventional sensors would miss basic transitory phenomena.
What yield signals are available?
We offer different yield alternatives to coordinate your framework prerequisites. Analog signals incorporate 4-20 mA current circles and 0-10V voltage yields. Computerized communication alternatives incorporate Modbus, HART, RS485, and I2C conventions for integration with advanced control systems.
Can you customize the transducer for particular applications?
Absolutely! Our free R&D group specializes in fitting sensors to your correct details. We can adjust weight ranges, yield signals, mounting arrangements, and natural evaluations to coordinate your application necessities perfectly.
