Lambda Sensor LSU 4.9 0258.017.025-U5G

Lambda probe LSU 4.9 BOSCH 0258.017.025-U5G.

This sensor detects the structural vibrations of spark-ignition engines caused by uncontrolled combustion, ensuring precise monitoring even in extreme conditions. Its seismic mass moves with the engine block vibrations, generating a voltage signal via a piezoceramic element. This allows for directly defining voltage thresholds corresponding to acceleration levels.

Its main advantages include a robust design, a compact housing, and high-precision detection of structural noise. Customizable with different cable lengths and connector options, this sensor adapts to the specific needs of customers.
