Design and Application of the Testing System for a New Pipe Pressure Sensor

Abstract:

The new pipe pressure sensor is a clamp-on ICP (Integrated Circuit Piezoelectric) type dynamic pressure sensor, mainly for the clamp-on pressure testing of high pressure fuel pipe. In testing, the vibration of the fuel injection pumps and diesel engine will disturb the clamp-on pressure signals, resulting in one of the measured signal to noise ratio is low, the second is the test system, in particular the signal transmission have a significant impact. In response to these problems, designed a PCI data acquisition card building-in constant-current source and special low pass filter, and developed the corresponding data acquisition software based on C++ Builder. The bench and real vehicle testing show: the test system can better fit with the new type pressure sensor to obtain accurate clamp-on pressure signals.
