The utility model relates to the technical field of pressure detection, in particular to a photoelectric conversion type liquid pressure sensor which comprises a first shell, one side of the first shell is fixedly connected with a second shell, one side of the first shell is fixedly connected with a first optical fiber, one side of the second shell is fixedly connected with a second optical fiber, and the second shell is fixedly connected with a second optical fiber. An adjusting assembly is fixedly connected to the interior of the first shell. The liquid pressure sensor has the advantages that the adjustable range of the light-pass slit device is 0.5-3mm (the gap of the adjusted slit is 0.5-3mm and is not in a diffraction range, and light is propagated along a straight line) by utilizing the light-pass slit device which is arranged on one side of the liquid pressure sensor and is adjustable in pressure, the opening degree of the adjusted light-pass slit device determines the amount of luminous flux, and the
