When your diesel motor needs exact emanation observing, choosing the right debilitate gas sensors gets to be significant for ideal execution. Our Diesel Nitrogen Oxide (NOx) Sensors deliver exceptional accuracy and reliability for SCR aftertreatment frameworks. With over two decades of involvement since 2001, Xi'an Qintai Car Emanation Innovation gives cutting-edge sensor arrangements that offer assistance your vehicles meet exacting emanation guidelines whereas keeping up top efficiency.
Your diesel motor works in requesting conditions. That's why you require sensors built to withstand extraordinary temperatures and cruel situations.Qintai progressed sensor innovation guarantees reliable execution over different applications.
Qintai sensors convey surprising precision over their whole estimation extend. You get exact NOx discovery from 0 to 2500 ppm with extraordinary determination. The quick reaction time of less than 1400ms implies your SCR framework reacts rapidly to changing emanation levels.
Exceptional Durability Design
Advanced Communication Capabilities
Your framework integration gets to be consistent with our comprehensive communication conventions. We back over 300 diverse conventions, guaranteeing compatibility with different ECU frameworks and demonstrative platforms.

Your SCR aftertreatment framework depends on precise NOx estimations for ideal operation. Our Diesel Nitrogen Oxide (NOx) Sensors work as upstream and downstream screens, giving real-time information to your motor control unit.
Upstream Monitoring Benefits
The upstream sensor identifies approaching NOx levels entering your SCR catalyst. This data makes a difference your ECU calculate the exact sum of urea (AdBlue) infusion required for successful outflow reduction.
Downstream Verification
Your downstream sensor affirms the SCR system's proficiency by measuring post-catalyst NOx levels. This dual-sensor approach guarantees greatest outflow lessening whereas avoiding over-dosing of diesel debilitate fluid.
Every application has one of a kind necessities. We get it this challenge and offer comprehensive customization administrations. You can indicate connector sorts, cable lengths, and mounting arrangements that coordinate your specific establishment needs.
Qintai building group works closely with you to create arrangements that coordinated consistently into your existing frameworks. Whether you require altered sensor lodgings or specialized communication conventions, we adapt our sensors to meet your exact specifications.

Quality drives everything we do. Our fabricating forms take after strict ISO9001 and IATF16949 guidelines. We've earned different worldwide certifications counting CE, UL, REACH, and RoHS compliance.
With 86 devoted R&D specialists and 58 development licenses, we ceaselessly improve to make strides sensor execution and unwavering quality. Our yearly generation capacity surpasses two million sensors, serving major Chinese motor producers like Weichai Control, Yuchai Control, and Quanchai Power.

Your victory things to us.Our specialized bolster group gives comprehensive help from starting item determination through establishment and progressing support. We offer nitty gritty documentation, preparing materials, and investigating guides to guarantee ideal sensor performance.
