The Western Instruments N88-11 Jr. Bridging Pit Gauge is used to measure Dents and Buckles on Pipelines, Shell Settlement on Storage Tanks, etc. These various forms of Bridging Bars can utilize any of our exclusive Dial Indicators (Imperial, Metric, or Digital), with any of our Custom Engineered Contact Points. Western's advanced Bridging Pit Gauge System and our new Jr. Bridging Pit Gauge take over, where the capabilities of our standard Pit Gauges fall short, for evaluating large areas of Weight loss Corrosion. There are several important features to a Segmented Bridge, where various elements (Blades and Tees) are assembled to form a Bridging Bar. Firstly, they can be assembled to follow the contour of a slightly irregular surface. This contouring feature is important for Pipeline, Storage Tank, and Pressure Vessel inspections, where 'hills and valleys' always exist. Secondly, the models listed below are of a given length, however extra elements can be added to increase their over all length. As illustrated, these units can be assembled in Spanning or Cantilevering configurations, and finally, the Main Blade can be used individually for isolated or cone type Pitting.

The Multi-Weld Gauge is a precision instrument that provides an easy to read measurements of the following welding and fit-up parameters; Internal Hi-Lo, Gap, Filet Height and Leg Length, Weld Height, Undercut Depth, Misalignment, and Angle of Preparation. The Multi-Weld Gauge is equipped with 3 separate scales for all measurements. Metric and Imperial (Thousands of an inch and fractions of an inch). Rules for liner measurements are located on the top and bottom of the Front side of the Scale Plate. The Multi-Weld Gauge is also equipped with 7 unique diameter comparators which are half circles in 1/16" to 1/2" in 1/16" increments (1.6mm to 12.7mm in 1.6mm increments) for convenient diameter estimates (Filet Welds, Welding Rod/Wire, etc.)The Multi-Weld Gauge does away with Single Purpose Welding Gauges, by consolidating the functions of the 4 most popular gauges, with over 9 measurement functions. The contrast of the scales against the black background, make the Multi-Weld Gauge extremely easy to read on any of its measurement scales. The Multi-Weld is unique, a distinct improvement over existing gauges.Weld and Fit-Up parameters are outlined in numerous industry specifications, such as; AWS, ASME, API, ANSI, ISO, DIN, CEN, and Military Specifications. Of particular importance for AWS Inspectors, the Multi-Weld Gauge will resolve and measure Undercut to +/- 0.010 (0.5mm), something no other Lever Type Welding Gauge can do.
