Gauge Types: Understanding GO and NO GO Features

The question asks to identify the gauge type where the 'GO' and 'NO GO' measuring components are located on different ends of the gauge body. This design facilitates checking both tolerance limits efficiently.

Analyzing Gauge Designs

• GO and NO GO Gauges: These are limit gauges used to verify if a dimension of a workpiece falls within the specified tolerance range. The 'GO' plug or member represents the maximum permissible limit (e.g., maximum diameter), and the 'NO GO' plug or member represents the minimum permissible limit (e.g., minimum diameter).
• Double-ended Gauge: This type of gauge is specifically constructed with measuring members at both extremities of the gauge body. It is common for one end to be designated as the 'GO' gauge and the other end as the 'NO GO' gauge. For example, a double-ended plug gauge has a 'GO' pin on one end and a 'NO GO' pin on the other, allowing for quick inspection of both limits by flipping the gauge.
• Progressive Gauge: Unlike a double-ended gauge, a progressive gauge typically integrates the 'GO' and 'NO GO' sections onto a single measuring end. The 'GO' section leads, followed immediately by the 'NO GO' section, allowing for checking both limits in one insertion motion but not on separate ends.
• Radius Gauge & Feeler Gauge: These gauges serve different purposes. Radius gauges measure the curvature (radius) of fillets or rounds, while feeler gauges measure the clearance or gap between two surfaces. Neither is primarily designed with distinct 'GO' and 'NO GO' members on separate ends for dimensional tolerance checks.

Conclusion on Gauge Configuration

Based on the defining characteristic of having 'GO' and 'NO GO' measuring members on separate ends of the gauge body, the Double-ended gauge is the correct classification.
