A kit, for analyzing and monitoring a parameter of a reaction in a reaction chamber, includes: a hollow tube fastened by its ends to the reaction chamber; and a capsule provided with a sensor and guided along the hollow tube via a magnetized magnetic piston disposed in the hollow tube and controlled by a guide device. The hollow tube imposes a predetermined trajectory on the capsule to maintain the capsule at a distance from any mobile member to prevent the capsule from damage. The hollow tube can extend over the entire depth of the reaction medium to allow measurements over the entire depth of the medium.

The method involves a step of measurement of a bearing force (Fp) on a pedal () of the pedal set (), different from the useful effort, exerted by the individual during a pedalling cycle, a step of determination of a maximum (max(Fp)) of the bearing force measured during the pedalling cycle (CP), and a step of estimation of a mean useful effort exerted by the individual during said pedalling cycle from the maximum of the bearing force determined and with the aid of a predetermined correlation function between a maximum bearing force during a pedalling cycle and a mean useful effort in said cycle.

A bicycle pedal including a tube, assembled to freely rotate around an axis, and a pedal body including at least one first surface on which a cyclist is capable of exerting an effort, the pedal body being connected to the central tube by at least one connecting member including a first portion interposed between the tube and the first surface and fitted with at least one deformation gauge.

Dynamometric cycle pedal

A method and system for measuring the output power produced in a device having a crankset, includes: measuring the orthogonal force exerted on at least one pedal of the crank; determining the angular velocity of the crank; and deducing the tangential force exerted on the crank and the power, using a pre-established model of the distribution of the force exerted on the actuating member as a function of the angular velocity.
