Abstract
A glow plug assembly includes an integrated, internal pressure sensor. In order to reduce loading on the center electrode, improve sensor responsiveness, and provide better thermal performance, the pressure sensor assembly is housed in a canister which forms a containment capsule and rigidly connects inside the glow plug shell near its seat area. The pressure sensor makes direct contact with the base end of the heater probe so that movements of the heater probe caused by fluctuations in gas pressure lead directly to changing force on the sensor stack.
