Abstract: Analytical instrument inductors are provided that can include bundled wired conductive material about a substrate. Analytical instrument inductors are also provided that can include: a tubular substrate defining a plurality of flanges extending outwardly from a core of the substrate wherein opposing flanges define portions of the core; at least one pair of wires wound about a first portion of the core and between at least two flanges, the pair of wires extending to and wound about a second portion of the core; and wherein the one pair of wires are operatively coupled to an analytical instrument to provide inductance. Methods for preparing an instrument inductor are provided. The methods can include bundling wires about and within multiple exterior openings of a hollow-cored substrate; and connecting each of the bundles across the openings.

Abstract: A system and method employing a piezoelectric sensor for quasi-static force measurement substantially free of drift and with improved low-frequency response. The output signal from the sensor is sampled and integrated using digital techniques that include a drift compensation algorithm. The algorithm continually monitors the sensor output and estimates bias errors that will cause the output to drift.
