Profile: Kistler Instrument Corp. is a manufacturer of sensors for measuring pressure force, torque and acceleration. We are an ISO 9001 certified company. Our product line includes pressure, force and torque transducers, pressure, force, and torque sensors and accelerometers. Our force sensor generally measures the applied force from the proportional deformation of a spring element. The larger the force, the more this element deforms. The frequency range of this type of sensor is limited by this element having to be sufficiently elastic to undergo large-amplitude deflections reflecting the load. Our force transducer generally measures the applied force from the proportional deformation of a spring element: the larger the force, the more this element deforms.
