About the GCA-AE Series Air extend AC operated gage heads

The GCA-AE Series heavy-duty gage heads enable high performance in environments containing moisture, dirt, and fluid contaminants. 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.

The ruggedness, long life cycle, and very high reliability of the GCA-AE Series provide a low cost of ownership over the life of the equipment onto which they are installed. The one-piece front end (barrel which contains the bearing assembly), machined
from solid stainless steel bar, coupled with a bronze bushing, has far greater resistance to bending forces and side loads compared to other designs. This is particularly important on the longer stroke versions; it reduces the common risk of probe
damage/bending during installation or maintenance of industrial equipment. The GCA-AE Series designs also require fewer parts and weld joints, thereby increasing overall structural integrity and reliability.
