Description

A Linear Variable Differential Transformer (LVDT) is used for a single-axis remote position sensing system. Analog signal conditioning is provided by an AD598* from Analog Devices. The AD595 features "ratiometric" signal scaling, which makes it insensitive to a common source of measurement error; That error due to excitation amplitude variability. This variation can be due to external changes in operation, such as cable length changes or cable temperature variationThis design is "Live - Interactive", so the user can change any of the parameters shown in blue, and run new simulations to see the results of those changes. It may be interesting to verify the rock-solid digital (integer) output codes that represent the position extremes for this mechanical system, even when the cable length and temperature are varied over their full supported range.* This model of the AD598 is not certified by Analog Devices, and only represents behavior that is publicly described in the device datasheet.
