Description
Product Overview
The pressure sensor is threaded and installed on the high-pressure common rail pipe. An internal high-precision sensing chip captures the fuel pressure in the pipeline in real time and converts it into voltage signals recognizable by the electronic control unit. The system dynamically adjusts the oil pump supply volume and injection timing based on the signals. Under long-term conditions of thousands of bar high-pressure fuel flushing, alternating temperatures in the engine compartment, and diesel water and oil corrosion, the sensing element ages, and the bottom seal fails, resulting in distorted rail pressure data, power output discontinuities, rapid pressure relief during engine shutdown, the need for multiple ignitions to start the engine, and excessive black smoke in the exhaust. This product has standardized specifications for the threaded installation, signal output range, and pressure-bearing threshold. The sensor can be simply replaced for repair of abnormal oil pressure signal faults during maintenance of electric control common rail engines for light trucks, diesel pickup trucks, and small passenger diesel vehicles.
Core advantages of this product:
Thickened segmented stainless steel pressure-bearing shell, resistant to pressure, rust, and medium corrosion
Multi-layer stepped stainless steel integrated precision processing, thickened tube wall to enhance pressure-bearing capacity, capable of withstanding continuous ultra-high oil pressure impact, isolating cabin water vapor, diesel oil and gas erosion, and providing long-term protection for the internal sensing chip from damage.
Integrated hexagonal clamping platform at the bottom, with uniform force during disassembly and assembly, and not prone to damage
Complete hexagonal limit structure at the lower end, compatible with standard sockets / open wrenches, during disassembly and assembly, it will not squeeze the internal precision sensing elements, avoiding shell deformation, thread slippage, and fuel leakage.
Black multi-pin waterproof insulated electronic control plug, stable signal and anti-interference
Multi-pin integrated sealing socket, built-in dustproof and waterproof rubber gasket, isolating cabin oil, water vapor, and dust, eliminating short circuits, loss of oil pressure signals, no data transmission delay or drift.
The plug is marked with characters + QR code identifier for quick matching of models during inventory and maintenance
The surface of the plug is laser engraved with multiple identification codes and QR codes, resistant to diesel soaking, repeated wiping without code loss, quick differentiation of specifications during warehouse storage and on-site maintenance, avoiding incorrect installation causing abnormal oil pressure collection.
Built-in precision sensing chip, with extremely small error in oil pressure collection over the entire range
High-precision pressure sensing element, capable of detecting oil pressure in all working conditions from no load to heavy load with linear stability, the electronic control unit can precisely adjust the rail pressure, eliminating vehicle acceleration jolts and speed fluctuations.
Factory calibration of the entire machine signal, no need for secondary adjustment during assembly
Each sensor is independently calibrated for oil pressure - voltage corresponding curves, factory signal parameters are unified, after assembly, it can directly match the original vehicle electronic control system, quickly restoring the vehicle's smooth power output.
