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.
