The Pressure Measuring Spark Plug Kistler Model 6117B allows a pressure measurement without a drilled hole. In the Pressure Measuring Spark Plug Kistler Model 6117B, is integrated the worlds smallest piezoelectric high temperature, cylinder pressure sensor.

By an eccentric electrode arrangement the space for sensor mounting is provided. The miniature pressure sensor can be dismounted for maintenance purposes. However, in the normal case dismounting of the sensor by the customer is not recommended. The sensor is mounted from the front of the spark plug and fixed by means of a screw which also serves as flame protection. The cable Type 1927A1 can be dismounted.

This Pressure Measuring Spark Plug Kistler Model 6117B is installed flush with the combustion chamber, allowing for a natural frequency of more than 100 kHz. Therefore, the Type 6117B is also well suited for indicating measurements at high engine speed. This sensor is also available in a version Type 6617B with impedance converter integrated in the cable connector (voltage output).

• Measuring without measuring bore
• Highest natural frequency (up to 100 kHz) for high rpm
• Sensor mounted flush with the combustion chamber
• High sensitivity
• High accuracy
• Different heat values available
