A method for determining the vibration of turbomachine rotor blades, including steps of measuring, via one or more sensors, the variation in the minimum distance between each sensor and the top of each blade along a radial axis of the rotor, between successive rotations of each blade in front of each sensor, a minimum distance value being obtained on each passage of each blade in front of each sensor, in order to deduce therefrom a variation in the lengths of the blades along the radial axis; and, using directly, as such, the variation in the length of the blades along the radial axis in a model of the deformation of the blades, in order to deduce therefrom characteristics of one or more vibrational modes of the rotating blades. A turbomachine can be equipped with a device implementing this method.

A belt monitoring system for an agricultural belt arrangement, the monitoring system including an agricultural belt having a magnetic element embedded therein and a sensor. The agricultural belt arrangement defines a proper belt alignment for the belt and moves the belt. The magnetic element is polarized so as to output a magnetic signal. The sensor is configured to detect, at a reference position, the magnetic signal outputted by the magnetic element. The monitoring system further includes a circuit configured to output a signal if, for example, the agricultural belt moves more than a predetermined amount through the agricultural belt arrangement without the sensor arrangement detecting the magnetic signal outputted by the magnetic element, a predetermined amount of time passes without the sensor detecting the magnetic signal, and the circuit determines the position of the magnetic element to be outside of a permissible positional range.
