SHAFT MULTIPHYSICS MEASURER

WIPO Patent Application WO/2023/245943

A1

A shaft multiphysics measurer, comprising a housing (1) provided with an inner cavity and a circuit board assembly (2) mounted in the inner cavity. The circuit board assembly (2) is integrally provided with at least two sensing modules used for measuring different physical parameters and comprises a plurality of rigid circuit boards (21) arranged in the extending direction of the inner cavity and flexible circuit boards (22) electrically connected between the different rigid circuit boards (21). According to the shaft multiphysics measurer, at least two different physical parameters in a shaft can be measured by means of the sensing modules integrally provided on the circuit board assembly (2), and the size of the circuit board assembly (2) is effectively reduced by using the characteristic that the flexible circuit boards (22) are easy to bend, such that a circuit is miniaturized, and a measuring tool is more compact in structure and smaller in size.
