Dimensional Gaging Probes, LVDT-Based

Macro Sensors has introduced a new line of LVDT-based Dimensional Gaging Probes that provide highly accurate and precise measurement of dimensions in a wide variety of quality control, inspection equipment and industrial metrology applications including online parts inspection, servo-loop positioning systems, and manufacturing process control. Available in four models including full bridge, half bridge, pneumatic and soft touch, the BB Series LVDT-based dimensional gaging probes can be used in automotive, medical, and aerospace manufacture to control the precise dimensional parameters of their products. These AC-operated LVDT gage heads can measure the position of a target surface, with an unusually high degree of accuracy. Complete systems for "go/no/go" inspection of complex mechanical parts can be assembled using several gage heads mounted in suitable fixtures. The probes combine a special AC-LVDT with a linear ball bearing assembly to reduce radial play and core skewing, resulting in exceptional repeatability of 0.000006 inch (0.15 microns). The use of an LVDT for probe shaft displacement sensing eliminates any additional transducer errors due to friction, stiction or mechanical hysteresis. The BB Series also offer unusually long life of 2 x 108 cycles. The company manufactures a full line of support electronics for these spring-loaded LVDTS including OEM modules, DIN-rail mount line-powered and DC-operated signal conditioners and digital display and control instruments.
