ABSTRACT:
A load cell suitable for the measurement of discrete events having an output substantially free of resonant frequencies is disclosed. The load cell includes a visco-elastic polymer bonded thereto as well as accompanying control circuitry for maintaining the visco-elastic at a constant temperature to stabilize the load cell output in the event ambient temperature varies.
