The high-pressure common rail pressure sensor measures the real-time pressure of fuel in the common rail with sufficient accuracy in a short period of time, and converts the pressure signal into a voltage signal while transmitting it to the ECU, achieving control over injection accuracy and timing.
High pressure common rail pressure sensors are generally installed on common rail pipes, with a measurement range of usually 0-200MPa. Generally speaking, pressure sensors cannot be disassembled from the common rail pipe. If they are damaged, the common rail pipe must be replaced at the same time.
The fuel of the engine flows into the rail pressure sensor through a hole on the common rail, and is sealed at the end of the hole by a sensor core. The fuel under high pressure reaches the sensor elastic body through a blind hole. A sensor element (semiconductor component) is arranged on the elastic body, which converts pressure into an electrical signal. The generated electrical signal is transmitted to the evaluation circuit through a wire, which amplifies the signal and sends it to the ECU
The high-pressure common rail pressure sensor developed by our company based on RPT8100 adopts glass micro melting pressure sensor technology, with a maximum range of 600MPa. The mature and stable process ensures that the product is stable and reliable for long-term application in the high-pressure common rail industry of diesel engines.
