To provide a physical quantity measuring device or the like capable of detecting a fault of a humidity detection part.SOLUTION: A measuring device 100 is a physical quantity measuring device for measuring physical quantity of fluid. The measuring device 100 includes at least two humidity detection parts 60 and a fault detection part 73. The respective humidity detection parts 60 for example output a humidity signal corresponding to humidity of fluid, such as air. The fault detection part 73 determines that the humidity detection parts are abnormal when a difference in humidity signals acquired from the two humidity detection parts 60 exceeds a fault determination threshold.SELECTED DRAWING: Figure 3 【課題】湿度検出部の異常の検出が可能な物理量計測装置等の提供。【解決手段】計測装置１００は、流体の物理量を計測する物理量計測装置である。計測装置１００は、少なくとも二つの湿度検出部６０と故障検出部７３とを備えている。各湿度検出部６０は、例えば空気等の流体の湿度に応じた湿度信号を出力する。故障検出部７３は、二つの湿度検出部６０から取得した湿度信号の差が異常判定閾値を超えた場合に、湿度検出部に異常が生じていると判定する。【選択図】図３
