LVDT Sensor GCD-AE Series

Image GCD-AE

GCD Series gage head with stainless steel construction enables the performs in environments containing moisture, dirt and other contaminants.

Electronic components are hermetically sealed for added protection against hostile conditions.

These are heavy duty, long stroke units with ranges up to ±1.0" (25.4mm). These Gage heads are air-extend, spring-retract LVDTs (Linear Variable Differential Transformers) with precision linear bearings.

The working end or probe has a removable chrome plated, hardened tool steel tip threaded to the probe with a 4-48 UNF-2A threading. Schaevitz® replacement and alternate contact tips are available.

Tips are also interchangeable with AGD dial indicator tips. Internal construction prevents the core and shaft from rotating as they move longitudinally.

Units terminating into connectors allow for easy cable replacement if damage should occur. Installation and adjustment are facilitated by external threading; locknuts are provided. Units incorporate the core, LVDT and all necessary electronics in one housing.

Use of monolithic, surface mount circuitry eliminates most of the volume, weight and cost of conventional AC excitation, amplification and demodulation equipment.
