Example Valve Lift Measurement Valve Stem to Guide Clearance Measurement
Installation Diagram
Purpose of Measurement The amount of lift in the valve is measured without changing the valve. Multiple sensors are attached to the valve guides to measure the gap displacement (valve behavior) between the valve stem and valve guide.  
Specifications Operating Temperature: 180C Maximum

Measuring Range: 0 to 15mm

*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.
