GCD-SE Series Single Ended DC Gage Heads • Hermetically sealed housing • Single ended to 24VDC supply • Low current consumption only 6mA • Ideal for battery operation • IEC IP68 rating to 1,000 PSI [70 bars] • Long strokes up to 2 inches • Hardened tool steel contact tip • High side load resistance The GCD-SE Series of heavy-duty DC operated gage heads enable high performance in environments containing moisture, dirt, and fluid contaminants. With a spring loaded LVDT, a precision linear bearing, and internal conditioning electronics operating on a single ended to 28VDC input with minimal current draw, the GCD-SE is ideally suited to portable measurement applications in difficult environments. Internal EMI, ESD and RFI protection, provide CE compliance when correctly installed. Synchronous demodulation ensures unsurpassed noise rejection. These robust gage heads allow measurements over stroke ranges from 0 to inch [2.54mm] up to 0 to 2 inches mm]. 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 mounting thread and the two locknuts supplied with each unit. Like in most of our LVDTs, the GCD-SE 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 GCD-SE 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 GCD-SE Series designs also require fewer parts and weld joints, thereby increasing overall structural integrity and reliability. MEAS offers options, such as mating connector plugs, special contact tips including AGD dial indicator tips , airextend/spring retract, and cable assemblies. Also see our other models with built-in signal conditioning, GCD DC voltage , GCT 4-20mA 2-wire loop and GC-485 RS-485 Digital Series , as well as the AC operated GCA. Measurement Specialties, Inc. NASDAQ MEAS offers many other types of sensors and signal conditioners.
