The miniature measuring probe with very small dimensions and M5 x 0.5 mounting thread is particularly suitable for direct
installation in small-capacity combustion engines with more than 2 valves per cylinder.
Type 6053BB uses a new type of piezoelectric crystal with which a sensitivity of -20 pC/bar is achieved. The sensitivity over a temperature range of 200 +/-50°C varies by not more than +/-0.5%. The influence of engine vibrations on the measuring signal is reduced by the passive acceleration compensation.
Installation through the coolant channel is possible without
expensive modification of the cylinder head, and without an additional mounting sleeve. Sealing against coolant leakage
is provided by O-rings fitted to the sensor. The front seal allows good heat dissipation and thus a maximum short-time
probe operating temperature of 400°C.
• Good temperature stability of the sensitivity
• Acceleration-compensated
• Needs only 6 mm mounting bore
• Low thermal shock error and long life thanks to the front seal
• Very high sensitivity
