Dimensional Gaging Probes DGP Series

The DGP Series Dimensional Gaging Probes by Alliance Sensors Group are AC-LVDT based, spring-loaded linear position sensors designed for high precision dimensional gaging applications. Widey used in the automotive, aerospace, and medical industries for machined parts manufacture, Gage R&R, and CpK data, the DGP Series has the precision necessary to make measurements to uphold six-sigma programs. Available in three ranges, the DGP Series spring loaded LVDT has an 8mm diameter, IP-65 rated housing that is slightly shorter than most competitive units. A light spring force of less than 1.25 lbs/inch holds the DGP probe in contact with the part but is light enough not to deform the product. Precision ground bearings and an anti-rotation pin allow the DGP to hold sub-micron repeatability and resolution. A rubber boot over the probe shaft keeps contamination out of the linear bearing. Alliance Sensors Group offers the SC-100 DIN-rail signal conditioner for use with the DGP Series LVDT probes, permitting the user very easy push button calibration. The SC-100 excites a DGP with the proper AC voltage and frequency,and then demodulates and amplifies the DGP’s AC output to produce the user’s choice of sev- eralanalog DC voltages or 4-20 mA current output signal.
