Automatic paired LVDT probe balancing

摘要

The apparatus and method of the present invention overcome the difficulties of balancing paired LVDT probes via provision of a quick and inexpensive process that can be implemented in either hardware or software. In particular, a software method is provided for determining a balance correction factor for paired probes in a LVDT gauging system. The balance correction factor is found through a procedure in which an operator moves a part under measurement within a fixture to which the probes are installed. The balance correction factor is then used to mathematically normalize A/D counts from individual paired probe circuits into a single result for each pair.
