Kistler Models 9077B, 9078B, 9076B4 3-Component Force Sensors
The Kistler Models 9077B, 9078B, 9076B4 3-Component Force Sensors contain 3 pairs of quartz rings which are mounted between two steel plates in the sensor housing.
Two quartz pairs are sensitive 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 different components are led via electrodes to the corresponding connectors.
The quartz packet is protected by the stianless, tightly welded sensor housing.
