GCT SERIES 4 to 20mA loop Gage Heads

PublishTime：2021-04-25

● The GCT Series heavy-duty gage heads enable high performance in environments containing moisture, dirt, and fluid contaminants. With a spring loaded LVDT, a precision linear bearing, and internal signal conditioning electronics operating on a 4 to 20mA loop, the GCT is ideal for difficult industrial environments and remote locations where sensor power is not readily available and long cable runs are expected. The 4-20mA signal is less susceptible to EMI and RFI interference than low amplitude AC or DC signals.
● These robust gage heads allow measurements over stroke ranges from 0 to 0.250 inch [6.35mm] up to 0 to 2 inches [50.8mm]. The spring force is typically 9oz [255 grams] at fully compressed electrical stroke. 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 GCT 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.
● The ruggedness, long life cycle, and very high reliability of the GCT Series provide the lowest 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 GCT Series designs also require fewer parts and weld joints, thereby increasing overall structural integrity and reliability.
