About the GCD-AE Series Air extend DC operated gage heads

The GCD-AE Series heavy-duty DC operated 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 and internal conditioning electronics. Operating on a nominal ±15VDC supply, the GCD-AE Series delivers an extremely linear, low noise ±10VDC output.

These robust gage heads allow measurements over stroke ranges from ±0.05 inch [±1.27mm] up to ±1 inch [±25.4mm]. A removable blackchromed, 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 GCD-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 GCD-AE Series designs also require fewer parts and weld joints, thereby increasing overall structural integrity and reliability.
