This instrument consists of a turntable and force sensor with microcomputer signal conditioner and two line LCD readout. Developed for bowling ball balancing. This sensor consists of an elastic plate with a capacitance electrode array. It is able to measure both normal and parallel forces dynamically and thus can resolve the force on the pad at each point into x,y, and z components as a function of time. The sensor determines position by a capacitance pattern on a movable element.
Signal conditioning is done by a small microprocessor.
Dielectric constant and temperature compensation is automatic. Sensor A series of capacitance type moisture sensors were developed. One version is implantable in soil. Another measures moisture in grain and other agricultural products, and may be combined with the level sensor. Linearity is comparable to a LVDT but this sensor features smaller size, lower cost, and EMI immunity.
