HEAVY DUTY AIR EXTEND GAGE HEAD

These Gage heads are air-extend, spring-retract LVDTs (Linear Variable Differential Transformers) with precision linear bearings.  These robust high-temperature gage heads allow measurements over long strokes up to ±1 inch [±25.4mm]. A removable black-chromed, hardened tool steel tip is threaded (4- 48UNF-2A) to the working end. Internal construction prevents the core and shaft from rotating as they move longitudinally. The integral electrical connector (welded) provides for easy installation and allows replacing a damaged cable without sacrificing the sensor. Installation and adjustment are facilitated by an external ½-20 mounting thread and the two locknuts supplied with each unit. Like in most of our LVDTs, the GCA-AE windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high vibration and shock.
