A moving handrail monitoring system (60) for a passenger conveyor (10) comprises at least one magnetic sensor (62) provided adjacent to a moving handrail (22) of the passenger conveyor (10), wherein the or each magnetic sensor (62) is configured to detect a change in magnetic flux resulting from motion of the moving handrail (22) and provide an output signal. A controller (64) is coupled to the or each magnetic sensor (62). The controller (64) is configured to: receive the output signal from the magnetic sensor (62), determine a change in a distance (X) between a surface (25) of the handrail (22) and the magnetic sensor (62) based on the variation in the output signal from the magnetic sensor (62); and calculate a handrail tension based on the change in distance (X).
