The invention discloses an oil pressure sensor consisting of two retractable parts, wherein the outer layer of each part is provided with a conductive shell with a circular arc inner hole, the inner layer is provided with a circular arc metal card, and the middle layer is provided with a piezoelectric layer made from piezoelectric materials; the inner layers, the outer layers and the middle layersof the two parts are correspondingly combined; and the shell is provided with a wiring terminal. By adopting a novel piezoelectric detection technology, the oil pressure sensor has higher measurementprecision; furthermore, the oil pressure sensor only needs to be clamped on the outer wall of an oil pipe in use, thereby having simple operation and convenient use and realizing the dynamic pressuredetection.
