“Which sensor type is necessary in which mounting situation?”
Mechanical modifications of cylinder head Use of existing standard bores
probe plug thread spark-plug glow-plug
• slim sensor design
• also for glow-plug
adaptation
• less thermal deformation
• less influence of
mounting bore
• best heat dissipation
• simple installation
• no indicating passages necessary
• custom tailored design
2.1 PRODUCT SELECTION GUIDE
Depending on the engine and measurement task for which a pressure sensor
is required specific sensor types should be used. The choice of the sensor
type typically defines the maximum achievable precision. In general two
mounting families can be distinguished. One is the situation where a modification
of the cylinder head of the engine e.g. drilling and milling of indicating
passages is feasable and the other where modifications are not possible. If
the available space is very limited or a modification is not possible a glow- or
spark-plug adaptor solution is an option. On the other hand if a modification
of the cylinder head is allowed it opens up the choices between several sizes
of threaded, plug or probe type sensors.
