Spring Or Pneumatic Analog Gauging Probes

In an analog gage probe, two small transformers share a common magnetic core. As the core moves, the output of one transformer increases and the other decreases. The out-of-balance current provides the measure of the core’s position. LVDT’s operate on an ac energizing voltage and require special signal conditioning.
