Description
### Product Overview
The common rail pressure sensor is installed on the fuel common rail pipe. The internal sensing element continuously monitors the high-pressure fuel pressure and converts the pressure value into an electrical signal, which is then transmitted to the vehicle electronic control system. The electronic control unit uses the signal to control the metering valve and the pressure regulating valve to adjust the oil pressure. Under long-term high-pressure fuel impact, erosion by oil impurities, and alternating cold and hot conditions, the sensing element ages and internal seals leak, causing signal drift and data interruption, which can lead to engine power limitation. This product is standardized in terms of thread specifications, wiring interface, and pressure output parameters. When faults occur in the fuel system, individual components can be directly replaced, and it is suitable for various vehicles equipped with high-pressure common rail diesel engines and for maintenance and repair of construction machinery.
Core advantages of the product
1. **High-strength stainless steel pressure-bearing shell, resistant to high pressure and diesel oil corrosion**
The shell is made of stainless steel and is precisely processed. It can withstand high pressure impacts and resist long-term erosion by diesel medium. The thread strength is stable and does not slip, and the pressure-bearing channel is not prone to deformation or cracking.
2. **High-precision built-in sensing chip, precise and stable pressure collection**
Equipped with precise pressure sensing components, the signal has excellent linearity. The pressure collection error is small under all working conditions such as idle, acceleration, and heavy load, ensuring the precise regulation of fuel supply pressure by the electronic control system.
3. **Integrated sealed pressure-bearing channel, eliminating high-pressure fuel leakage**
The internal structure adopts multi-layer sealing technology, which can withstand continuous high-pressure impacts and prevent fuel from seeping into the sensor electronic area, avoiding component short circuits and damage.
4. **Standard-sized electrical connector, reliable contact in vibration environment**
The connector's shape and pin layout are standard and match the corresponding wiring harness connectors. It is unlikely to loosen or short-circuit under continuous vibration and shock conditions of the vehicle, avoiding intermittent engine shutdown and abnormal power supply faults.
5. **Resistant to a wide temperature range working environment, adaptable to variable operation scenarios**
The electronic components have undergone high and low temperature aging tests. They can output signals stably under low-temperature cold start, long-term heavy-load high-temperature environments, with small performance fluctuations.
6. **Single-piece pressure calibration and detection for factory delivery, strong parameter consistency**
Each product completes multi-point pressure signal sampling and calibration. The output curve is unified. After maintenance and assembly, it can quickly restore the normal control logic of the engine.
