Kistler 3-Component Force Sensor Models 9251A, 9252A, 9250A4, 9251A4
The Kistler 3-Component Force Sensor contains 3 pairs of quartz rings which are mounted between two steel plates in the sensor housing. Two quartz pairs are sensitivie to shear and measure the force components Fx and Fy, while one quartz pair sensitive to pressure measures the component Fz of a force acting on the sensor. The electrical charges proportional to the different components are led via electrodes to the corresponding connectors.
The quartz packet is protected by the stainless, tightly welded sensor housing. The latter has two fine-machined reference faces parallel to the y-axis. These faces can be used to position the sensor and consequently the coordinate system.
