Overview: This document provides technical specifications and applications for various gaging and displacement transducers, specifically focusing on the Series 310-320 Long Stroke AC Gaging LVDTs and Series 350 General Purpose DC Gaging LVDTs.

Gaging Applications: The document describes applications such as profiling the curvature of glass surfaces and testing valve displacement by measuring lift during simulated engine combustion. Forced air extends the probe tip, and the spring retracts it in the absence of air.

ADT Applications: Angular Displacement Transducers (ADT) are used to monitor valve disc rotation, control flow, ensure proper tension in material processing, and track angular displacement. They are crucial for controlling engine speed and adapting to road conditions.

Series 310-320 Long Stroke AC Gaging LVDTs: These transducers feature a precision AC LVDT, stainless steel construction, and a spring-actuated shaft. They offer excellent non-linearity (<0.25%) and low temperature coefficients, suitable for applications requiring precision linear displacement measurement. Available in full stroke displacements from 0.5 to 20 inches.

Specifications: Key specifications include ranges from ±0.25” to ±10.0”, stainless steel construction, and a reversible spring option. The document provides detailed model specifications, including range, force, length, impedance, and phase angle.

DC-DC Operation: The Series 310-320 can be used with the Series 1000 Oscillator/Demodulator for DC systems, providing high-level DC output voltage compatible with analog circuits and data acquisition systems.

Series 350 General Purpose DC Gaging LVDTs: These transducers integrate a spring-loaded spindle, precision LVDT, oscillator, and demodulator. They offer high sensitivity, excellent linearity, and infinite resolution. They are designed for use in floating or ground return systems and can drive DC indicators and control systems directly.

Mechanical Specifications: The document includes detailed mechanical specifications for the Series 350, such as total length, shaft extension, tip force, and weight for various models.
