Gages / Gaging Systems


At Western, we focus on air and electronic gages that with a minimum amount of operator skill provide fast-accurate and cost effective measurements of parts in production shop floor environments.

For fast-accurate measurement of Internal and External Diameters consider using one of our dimensional air gages. Weve designed and manufactured dimensional air gages for over 40 years and know what works well and what doesn't. Air gage ranges are limited so they're not for every application; but for highly precise parts there is nothing better.

Besides checking I.D.'s and O.D.'s, we have proven air gage designs for checking taper angle, straightness of bores, concentricity, thickness, perpendicularity, center distance and parallelism. Fabricated in Western's gage manufacturing shop, they're fast-accurate and much less expensive than using coordinate measuring machines, roundness test tables, or surface profilometers to check these kinds of features. Does it make sense to employ expensive pieces of capital equipment when a fast-accurate custom built gage will do the job?

Micro IIi Readouts incorporate backlit LCD displays that flag out-of-tolerance conditions by changing color from green to red. Seven decade digital displays show actual feature sizes or deviations from nominal sizes. They also include analog bargraphs to graphically display the test piece condition relative to the product limits. Auto-Zero and Auto-span setting features make these instruments very operator friendly. USB & RS-232C serial data and process control outputs are standard.

Micro IIi model AEQ 42-11-60 with single master type air probe and master ring provides fast and accurate inspection of internal diameters.

RS-232 & USB serial data ports are standard on all Micro IIi ®s.

Multiple inputs with single display Auto-select models direct multiple inputs to a single display. As gages are sequentially inserted in the workpiece, the readout automatically senses the active gaging member and displays the reading. Up to four air gages or pairs of LVDT inputs can be connected to a single display.

LVDT Readouts Factory installed interface modules provide the capability to operate LVDT type inductive probes. (See inductive probes on catalog pages 34 &35).

Multi-Channel Micro IIi Readouts
Multi-channel Micro IIi readouts come with up to four input channels which can be configured for operation with either dimensional air gages and / or LVDT electronic gaging cartridges.

Micro IIi AEQ-42-32N-(XX) Dual Input Micro IIi models with three displays provide fast, accurate inspection of the internal and external diameters of mating parts. The upper display shows the I.D. size, the middle display shows O.D. size, and the lower display shows the calculated clearance between the parts.

Micro IIi Readout Technical Data
Digital display
Red-green backlited, 7 decade, LCD shows actual part sizes. Digital resolutions are set according to the Hi & Lo product limit span

Bargraph display
Red-green backlited, 81 segment bargraph, graphically displays the workpiece size and acceptance limits.

Out-of-tolerance Indicators
O/T conditions are flagged by changing the displays from green to red.

Auto-Zero feature (single master)
Micro IIi readouts configured for single master operation have their sensitivities set at the factory using master standards. These instruments are zeroed by the user placing a setting master on the gage and pressing the center key to Auto-Zero the readout.

Auto-Span feature (dual master)
Users set the sensitivity, and zero on Micro IIi readouts configured for dual master operation using Min & Max setting masters. Pressing the center key starts the Auto-Span setting cycle with prompts for the user to sequentially place the setting masters on the gaging member; the sensitivity and zero are then set automatically.
