Kistler Group 1-Component Low Force Sensor 9215A

The force to be measured acts through the cover and base of the tightly welded steel housing on the quartz sensing elements. Quartz yields an electric charge proportional to the mechanical load. The sensitivity (a material constant of quartz) and therefore the threshold, too, are practically the same for all load washers. This has three unique advantages: • Even very small forces can be measured with a sensor having a large range, which assures a high safety against overload • Similarly a sensor with a large range can be chosen when the highest possible rigidity (small deformation) is required • Several sensors can be connected electrically in parallel to a single charge amplifier whose output signal corresponds to the sum of all forces acting
