Abstract
(EN) A device for measuring forces and moments at a kinematic joint (6) of a cylindrical-parabolic solar collector, comprising a torque-measuring flange (1) on the rotational axis of the kinematic joint, a first load cell (2) parallel to the rotational axis of the kinematic joint, a second load cell (3), and a third load cell (4) in a position perpendicular to the rotational axis of the kinematic joint, and a bearing (5), where the first load cell (2) measures the compression and traction forces of the kinematic joint (6), the second load cell (3) and the third load cell (4) measure the forces perpendicular to the rotational axis of the kinematic joint, and the bearing (5) enables the monitoring of the load cells during a rotation of the kinematic joint (6).
(ES) Dispositivo de medición de fuerzas y momentos en una junta cinemática (6) de un captador solar cilindroparabólico que comprende una brida de medición de par (1) en el eje de giro de la junta cinemática, una primera célula de carga (2) paralela al eje de giro de la junta cinemática, una segunda célula de carga (3) y una tercera célula de carga (4) en una posición perpendicular al eje de giro de la junta cinemática, y un rodamiento (5), donde la primera célula de carga (2) mide la fuerza de compresión y tracción de la junta cinemática (6), la segunda célula de carga (3) y la tercera célula de carga (4) miden las fuerzas perpendiculares al eje de giro de la junta cinemática y el rodamiento (5) permite el seguimiento de las células de carga durante una rotación de la junta cinemática (6).
