DGP Series
Spring-Loaded LVDT Gaging Probes
Specifically Designed for Dimensional Gaging and Metrology

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.  Widely 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 8 mm 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 contaminants out of the linear bearing.

Alliance Sensors Group offers the SC-200 DIN-rail-mountable signal conditioner for use with the DGP series which provides the user with a very easy push-button calibration. The SC-200 excites a DGP with the proper AC voltage and frequency then demodulates and amplifies the DGP’s AC output to produce the user’s choice of several analog DC voltages or 4-20 mA current output signal.
