Digital LBB gaging probe system acquires precision data on machined parts
The new Digital LBB (linear ball bearing) system can accommodate up to 31 daisy-chained probes via an external power source.
The plug-and-play system is easily set up and implemented to ensure quality production in a variety of manufacturing environments. These include inspection of optics (mirrors, lenses), medical glass and cans as well as measuring wobble and run-out of rotating parts (rotors, axels), free-form dimensions (windshields, crankshafts, body panels) and diameter and run-out of machined parts (engine pistons, bearings). Materials testing and meteorology applications also benefit from the high precision measurements provided by this system.
Networked via T-Connectors, the digital gaging probes are available in either spring or air actuated versions with stroke ranges of 1, 2, 5 and 10 mm available. In addition to incorporating a precision linear ball bearing, each robust LVDT probe is mated to an in-line 14-bit, digital I/O signal conditioning module that performs calibration and linearity correction functions in the circuitry and firmware. This allows an extreme accuracy of either 0.1% of the reading or 1 µm, whichever is greater.
Repeatability is the greater of either 0.0065% of the range or 0.15 µm. The new system operates from 0ºC to +60ºC with a maximum current of 60 mA and can buffer up to 240 samples per second.
The new system offers a variety of connectors and tips for its gaging probes. It can be used as a drop-in replacement for or, using a Measurement Specialties T-Connector, as a fully-compatible version to similar industry systems.
