Example Piston Behavior Measurement Piston Ring Behavior Measurement
Installation Diagram
Purpose of Measurement Sensors are embedded in the connecting rod bearing, and the gaps between the crankpin and sensors are measured to evaluate the locus of crankpin centers. Sensors are attached to the main bearing of the crank journal to measure movement and gap.
Specifications Operating Temperature: Max 180°C

Measuring Range: Dependent on installation geometry, please contact us for assistance.

*These are reference specifications.  If your operating conditions require different specifications, contact AEC.  We may have the sensor you need or would be pleased to manufacture a sensor to meet your requirements.

Remarks The measurement range varies depending on sensor selection which depends on connecting rod size.  For example, if the PU-03A probe is used, the measurement range (linear output) will be 0-500mm with 6 x 6mm diameter drilled holes. The measurement range varies depending on sensor selection which depends on crankshaft journal size.
