With the aim of continuously improving the quality of all our products, Ryme Automotive has improved the quality of the components, sealing and reliability of its range of NOX Sensors. Ryme Automotive offers a complete catalogue of 12 and 24 V NOX Sensors for the Aftermarket distribution, becoming one of the suppliers with one of the most complete ranges on the market.
Dynamic Performance Curve
The dynamic performance curve is similar to OEM Sensors. Other competitors show a large deviation with the signal curve performance of the OEM product.
IP67 Rugged Structure
Ryme Automotive NOX Sensors have been manufactured with IP67 Protection Grade, which ensures anti-corrosion, however other brands do not meet this certification.
High Quality Components
We use components on PCB board that strictly comply with OEM. While some other competitors use different or integrated chips, which is much lower in cost but unstable.
Clamp in the joint area
We use high quality crimped steel clamps to prevent fraying of the cable at the junction area. Other competitors do not use clamps.
Electric connection
We use tin soldering on the electrical connections to ensure long-term electrical contact. Other competitors do not have this process, which will cause abnormal signal after a period of use.
High performance cabling
We use cables that withstand high temperatures, up to 350ºC, which guarantee greater durability of the Nox sensor.
Ceramic Technology
All our NOX Sensors include ceramic chips that guarantee the highest quality and the best performance similar to OEM products.
Calibration of sensor data
Each of our NOX sensors undergoes an independent data adjustment and calibration process to ensure product performance.
High Quality Chip Sealing
The sealing and insulation materials of the chips have been patented and guarantee the long-term strength and stability of the product.
