LVDT-based dimensional gaging probes from Macro Sensors are designed to provide accurate and precise measurement of dimensions in a 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 industries to control the precise dimensional parameters of products. “These AC-operated LVDT gage heads can measure the position of a target surface with a high degree of accuracy,” said a company spokesperson. “Complete systems for ‘go/no-go’ inspection of complex mechanical parts can be assembled using several gage heads mounted in suitable fixtures.” The BB Series LVDT Dimensional Gaging Probes combine an AC-LVDT with a linear ball bearing assembly to reduce radial play and core skewing, resulting in repeatability of 0.000006” (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 offers long life of 2 x 108 cycles. Other features of these spring-loaded LVDTs include: • User-adjustable pretravel • Reduced susceptibility to temperature changes • Positive stops prevent mechanical damage to the probe from repeated over stroking • Rubber bellows covering the probe shaft prevent the entrance of contaminants into the bearing. The BB units are available in three standard ranges: ±0.020” (±.5.0 mm), ±0.100” (±2.5 mm) and ±0.200” (±5.0mm) . Macro Sensors manufactures a full line of support electronics for these spring-loaded LVDTS including OEM modules, DIN-railmount line-powered and DC-operated signal conditioners and digital display and control instruments. By combining the BB Series position sensors with an EAZY-CAL Mini-Module LVDT Signal Conditioner, Macro Sensors offers a fully calibrated and complete linear position gaging system ready for immediate operation, said the company.
