Advanced Sensors

The Edibon AV-S features typical engine management system sensors (mass air flow, lambda, temperature, oil pressure, and accelerator pedal position sensors) and also includes sensors from the stability system, parking system, lighting system and the safety system.

The Automotive Sensors Unit, “AV-S”, provides a practical solution to familiarize the students with the sensors used in modern automotive systems.

The sensors included in the “AV-S” are focused on the measurements required for the engine management system, being the mass air flow sensor, the lambda sensor, different temperature sensor, oil pressure sensor, accelerator pedal position sensor, etc. but there are also other sensors for the stability system, the parking system, the lighting system and the safety system.

The “AV-S” unit is mounted on a metallic plate that can be used alone or assembled to the EDIBON workbenches.

All sensor circuits included in the unit are isolated to understand the function of the circuits separately. All connector points of the sensors circuits are accessible through 2 mm standard lab sockets.
