A new sensor for indirect force measurement, model 9234A, mounts on a convenient surface, reportedly eliminating the requirement to position deep within the equipment. Force is measured indirectly as strain by a piezoelectric element. The sensor includes an integral, miniature charge amplifier that the company says provides an output suitable for standard process control units. Especially suited to assembly processes such as press fits, punching, and crimping, the sensor is also packaged for industrial production floor environments. Using a single screw attachment, the high sensitivity reportedly makes high accuracy possible, even with rigid machine structures.
