Dynamometer, particularly for determining the seating weight in a motor vehicle

A dynamometer (10;

• 10a;
• 10b), in particular for determining the weight on a seat in a motor vehicle, having a pickup element (11;
• 11a;
• 11b), which has two bearing points (16, 17) spaced apart from one another, having a recess (27;
• 27a;
• 27b) in the pickup element (11;
• 11a;
• 11b) in the region between the two bearing points (16, 17), having a rodlike element (37;
• 50) not subjected to bending forces, whose free end, when a load is exerted on the pickup element (11;
• 11a;11b), is deflected by a force (F) to be measured, and having a measurement array (33) for detecting the deflection of the free end of the rodlike element (37;
• 50), wherein the measurement array (33) includes a magnet (32) and a magnetic-field-sensitive sensor (35), wherein the magnet (32) and the magnetic-field-sensitive sensor (35) are disposed stationary relative to one another, and wherein the magnet (32) is spaced closely apart from ferromagnetic material, characterized in that the magnet (32) is disposed inside an elongated recess (30;
• 30a;
• 30b) of the ferromagnetic material;
• and that the longitudinal axis of the recess (30;
• 30a;
• 30b) extends transversely to the direction of the force (f) to be measured and to the length of the rodlike element (37;
• 50).
