| 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: 180°C
      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.  |

       Measuring Range: 0 to 0.3mm *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 | Measurement is possible without changing the valve weight. However, the engine is not operational with this installation. | AEC can provide sensors with a variety of round surfaces to match your valve stem and guide geometry. Please contact us for assistance. |
