A small, rugged, 1/8” thick extruded aluminum body is used to deal with harsh environments. Ends are sealed at assembly. A single screw-on plug attaches the operating cable to the console.

Lear Engineering has re-introduced a system of PC based diameter measurement for up to 24 lines. The system was originally designed for aerospace contractors and government sponsored research labs – who could afford the expensive development costs. Their requirements for ruggedness, accuracy, reliability, and data storage far exceeded what was available from other commercial sources supplying diameter gages.

The new system considerably exceeds the original performance due to the phenomenal increases in processing speed, storage capacity, and cost/performance now available.

Best of all, because of the PC based system architecture, the cost is usually a lot less than when purchasing individual measurement heads.

The diameter measurement is non-contact and uses IR light emitting diodes as the light source and CCD arrays at the lens image plane for the measurement. Without the need for motors, vibrators, scanning mirrors, bearings, the resulting system offers unequaled reliability and stability in the measurement.

Also for reasons of reliability, cost, and space saving, only minor electronic functions are housed in the measurement head. All DC voltages and operating waveforms that are identical for each head are supplied from shared oversize components within the PC and console where space is plentiful. Also, for reliability, the shared DC power supplies are redundant in that if one fails, the other continues to supply all lines seamlessly.
