Pressure Sensor Glow Plug
An optimized combustion performance obtained by the sensor and electronics in the glow plug pin, are the key elements of the remarkable reduction of the exhaust gases that can be achieved with the correct Pressure Sensor Glow Plug.

BERU® Pressure Sensor Glow Plug:
Forward-looking solution for a green future

Holder of numerous innovation awards, the BERU® Pressure Sensor Glow Plug has been developed to meet one very specific purpose: provide one of the best responses to the demands made on diesel engine in terms of particle reduction. Current and future exhaust gas limit values for diesel vehicles already and further will mean a drastic reduction in particles and nitrogen oxide in each cylinder.
Technical features
- Optimised combustion: the PSG Glow Plug measures the pressure in the combustion chamber with an integrated sensor and reports this to the engine control electronics;
- Sensor principle: piezoresistive;
- Flexible heating rod for pressure transmission;
- Robust sealing element between body and heating rod;
- Miniaturised electronics integrated in the upper part of the glow plug;
- Calibrated and customer-specific programmed;
- Integrated concentric automotive plug.

1 - Plug
2 - High voltage connection
3 - Circuit board with electronics
4 - Measuring diaphragm
5 - Glow plug body
6 - Gasket
7 - Glow plug heating rod
