Xi'an Qintai Automotive Emission Technology Co. Ltd brings you enterprise-grade Fuel rail Pressure transmitter solutions engineered for superior performance. Since 2001, we've specialized in precision pressure sensing technology. Our transmitters deliver exceptional accuracy of ±0.5% to ±1.0% full scale with ultra-fast response time under 2 ms. Designed for both diesel common rail systems (0–1800 bar, extendable to 2500 bar) and gasoline direct injection applications (0–200 bar), our sensors meet stringent Euro 6 and EPA Tier 4 emissions standards. With annual production capacity exceeding two million sensors and 58 invention patents, we serve as the No. 1 core supplier to China's Weichai Power, Yuchai Power, and Quanchai Power. Our ISO9001, IATF16949, CE, and RoHS certifications guarantee consistent quality you can trust.

Your motor merits detecting innovation that never compromises. Our transmitter screens immediate fuel weight inside the rail and changes over physical estimations into high-resolution electrical signals for your Motor Control Unit.
This real-time criticism empowers your ECU to balance fuel pump yield and injector timing with microsecond exactness. You get steady fuel conveyance, ideal combustion effectiveness, and full compliance with cutting edge emanations regulations.
We've designed our sensors to dispose of weight swell impacts that destabilize fuel frameworks. This avoids disastrous motor disappointment caused by over-pressurization or lean-burn conditions. Your operations remain secured, and your upkeep costs drop altogether.
