Machinery Engine Parts Pressure Sensor 5594377 For Cummis QSK Diesel Engine

The sensing core uses a single crystal silicon piezoresistive chip (ASIC technology) and is encapsulated in a titanium alloy shell (Grade 5). It can resist a 200G mechanical shock + 50G vibration (in line with the MIL-STD-810H standard), and its life expectancy is enhanced by 5 times compared with that of traditional aluminium shell sensors.

The surface is coated with a diamond-like (DLC) film (with a thickness of 3μm), and its fuel/oil corrosion resistance is up to ASTM D471 Level 3, making it suitable for the poor quality fuel environment with a 500ppm sulphur content.

With an integrated temperature-pressure cross-compensation algorithm, the non-linear error is ≤±0.1% in the range of -40°C to 150°C, eliminating the risk of false alarms caused by thermal drift.

With a built-in life counter (based on the design of 10^9 pressure cycles), it can upload the remaining life prediction value in real time via the CAN bus (with an accuracy of ±3%) and give a warning 200 hours in advance about the risk of failure.

• Arctic oil pipeline: For the Arctic oil pipeline, during a -55°C cold start, the linearity within the range of 0-5MPa is maintained at ±0.08%.

• Deep-sea drilling platform: It is resistant to sea water vapour corrosion (with a Cl- concentration of 1500ppm) and can work continuously for 30,000 hours without drift.

• Desert mining card: In an environment with a dust concentration of 800mg/m³, its protection level remains at IP69K.

• Energy consumption optimisation: Real-time pressure feedback optimises the ECU control strategy, increasing the comprehensive fuel efficiency by 0.8% (measured data of the QSK60 model).

• Intelligent operation and maintenance: With an optional Bluetooth diagnostic module (with a power consumption <1mW), users can read the pressure waveform spectrum through the mobile phone APP and intelligently compare it with the Cummins million-level fault database, with a diagnostic accuracy ≥ 99.3%.
