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.
