The GC-485 Series heavy-duty, spring loaded gage heads are self-contained, ultra
precision, digital I/O devices for high performance measurements in environments
containing moisture, dirt, and fluid contaminants. The GC-485 eliminates the need for
expensive and error-prone analog to digital conversion by internally converting the
analog LVDT signals into engineering units (imperial or metric). The result is a fully
calibrated and traceable measurement device, ready for installation, and 100% field
interchangeable.
Operating on 8.5 to 30VDC supply, the GC-485 provides an addressable RS-485 loop
output (MODBus RTU and ASCII protocols) running at 119kBd baud rate and capable
of handling up to 32 devices communicating over two wires. MIN, MAX and TIR
readings are sampled and stored internally at a maximum update rate of 600 samples
per second, and are provided to the host on demand. A velocity output (inch or mm per
second) is also available, while an internal tare (zero) function affords maximum
measurement range flexibility.
These robust gage heads feature a removable black-chromed, hardened tool steel tip
threaded (4-48UNF-2A) to the working end. Internal construction prevents the core and
shaft from rotating as they move longitudinally. The welded electrical connector allows
replacement of a damaged cable without sacrificing the sensor. The external ½-20
threads and the two supplied locknuts facilitate installation and adjustment.
Like in most of our LVDTs, the GC-485 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 GC-485 provide a low
cost of ownership over the life of the equipment onto which they are installed. The one-
piece front end (barrel), machined from solid stainless steel bar, coupled with a bronze
bushing, has far greater resistance to side loads compared to other designs; it reduces
the risk of probe damage during installation or maintenance. The GC-485 design also
require fewer parts and weld joints, thereby increasing overall structural integrity and
reliability.
