Three-parameter measuring probe

The utility model discloses a three-parameter measuring probe, and belongs to the technical field of petroleum logging instruments. The utility model relates to a pressure sensor which comprises a shell and a sensor body, the sensor body is installed on the shell, the pressure sensor further comprises a piston assembly, the piston assembly is installed in the shell and connected with the sensor body, the shell comprises an upper shell body (1) and a sensor shell body (20), and the sensor body is installed on the sensor shell body (20). According to the utility model, the novel sensor is adopted, so that the sensor has longer service life and can be in more sufficient contact with slurry, and the measured data is accurate, reliable and good in consistency; in addition, the piston assembly enables the balance compensation cavity to be larger, and therefore it is guaranteed that the instrument can normally work in a higher-pressure and higher-temperature environment. 本实用新型公开了一种三参数测量探头，属于石油测井仪器技术领域。包括壳体和传感器，传感器安装
