While much attention is given to on-highway vehicles, off-highway equipment—such as excavators, tractors, and generators—also faces stringent emission regulations. These machines operate in demanding environments, where sensor reliability is critical. Ruize’s NOx sensors are designed to withstand ex

Early NOx sensors relied on electrochemical cells, which were effective but had limitations in response time and durability. Recent advancements have introduced solid-state sensing technologies, which offer faster response, greater accuracy, and improved resilience. Ruize has been at the forefront o

NOx sensors operate in one of the harshest environments in a vehicle—high heat, chemical exposure, and constant vibration. Common failure modes include thermal shock, contamination from oil ash, and electrical degradation. Ruize combats these issues through robust material selection, advanced protec
