Measuring Spark Plug Types 6115B... and 6118B...

Kistler: The use of spark plugs in cylinder pressure measurement has the major advantage of avoiding the need to form an additional bore. It exploits the means of access to the combustion chamber already provided by the plug, which then serves a double purpose. The development of measuring spark plugs over time has enabled the sensor to be brought favorably close to the combustion chamber. Kistler's spark plugs have long been renowned for their high acoustic resonant frequencies and very good signal quality. The latest series manages to build on these advantages.

The new M12 and M14 measuring spark plug Types 6115B ... and 6118B... offer significant advantages in handling and maintenance, in addition to enhanced indication quality.

The modular design consisting of a demountable connection cable, replaceable sensor and ceramic body enables efficient maintenance and repairs to be made right on the spot.

Flush-mounted installation of the measuring element enables a very high natural frequency of acoustic oscillation. As a result, these measuring spark plugs are suitable for application tasks on large engines, test rigs and also in vehicles.

Accuracy has also been improved as the result of further development of sensor technology.

The new measuring spark plugs are already available with the most common heat values. The product range is constantly being upgraded to include additional geometries and heat values.
