An air cylinder (50) is provided with a cylindrical cylinder (52) and a piston (51) that is moved by the pressure of a fluid fed to chambers (56, 57) disposed within the cylinder (52). A monitoring device (1) is provided with a heat flux sensor (10) and a detection unit (13). The heat flux sensor (10) is positioned at the cylinder (52) and detects the heat flux flowing in the cylinder (52) as a result of the compression or expansion of the fluid in the chambers (56, 57) corresponding to the operation of the piston (51). The detection unit (13) detects the operational state of the piston (51) on the basis of an output signal from the heat flux sensor (10). 种监视装置，气缸(50)具备筒状的缸(52)以及利用供给至设置在缸(52)的内侧的室(56、57)的流体的压力来移动的活塞(51)。监视装置(1)具备热通量传感器(10)以及检测部(13)。热通量传感器(10)设置于缸(52)，并检测利用与活塞(51)的动作对应的室(56、57)的流体的压缩或者膨胀而在缸(52)中流动的热通量。检测部(13)基于热通量传感器(10)的输出信号，检测活塞(51)的动作状态。
