Abstract
An air cylinder includes a tubular cylinder and a piston which is moved by pressure of a fluid supplied to a chamber provided inside the cylinder. A monitoring device includes a heat flux sensor and a detection part. The heat flux sensor is provided to the cylinder and detects heat flux that flows between inside and outside of the cylinder due to compression or expansion of the fluid in the chamber caused in accordance with the movement of the piston. The detection part detects the moving state of the piston based on the output signal of the heat flux sensor.
