Measuring range: 0 to 300 bar
Overpressure static: 1200 bar (optional 1500 bar)
Frequency range: 2 kHz
Thermal shock: 1500 RPM pmi = 10 bar < +/- 0.5 bar
Accuracy: < 1% Full scale
Max temperature at measuring cell: 300°C (short time 1 min 350°C)
Temperature range of SCU: -40°C to +75°C
Supply voltage: 18 to 32 VDC
SCU current consumption: < 50 mA (continuous operation); 250 mA (switch-on peak)
Output signal range: 4 to 20 mA
Electrical connector: HT0E10-6P-F42-A34-SPL acc. to MIL-C-26482
Thread: M14 x 1.25
Sensor dimensions: 52 mm, Ø 18 mm
Electronic dimensions: 138 mm x 18 mm
Tightening torque: 25 Nm

General specifications Degree of protection Optimum sensor life is achieved at an average temperature at the measuring element of 200-250 °C. The life expectancy of the sensor has been designed so that the life of 16,000 h or more can be achieved in a gas engine. at 1500 rpm. Mounting The sensor should be installed close to the combustion chamber, the length of the pressure bore between sensor and combustion chamber depends mainly on engine speed. Generally there are two possibilities for the installation position of cylinder pressure sensors: Head mounted or set-back mounted. Head mounted installation...
