The Western Instruments N88-TS Tube Sheet Pit Gauge is designed to fit inside most 1/2 inch OD (0.500i or 12.7mm) Boiler Tube, where the resulting Inside Diameter is just over inch 0.375 inch or 9.5mm. Without having stating the obvious, the Tube Sheet Pit Gauge will also test larger tube where reaching into the Tube is necessary.
The Tube Sheet Pit Gauge is designed to fit inside most inch OD (0.500 or 12.7mm) Boiler Tube, where the resulting Inside Diameter is just over ? inch (0.375 inch or 9.5mm). Without having stating the obvious, the Tube Sheet Pit Gauge will also test larger tube where reaching into the Tube is necessary
The overall length of the Tube Sheet Pit Gauge is 23 inch (600mm), with a working length of 12 inch (320mm) on the minimum diameter. The overall length is approximately 20 inch (500mm) with an overall diameter (clearance) of 1 inch (38mm). Specials can be ordered to reach into tubes much farther, within practical limits, and have been manufactured with a working lengths up to 1.5 meters
With the standard design of the Tube Sheet Pit Gauge, the operator doesn't typically have to be concerned with any deflection of the Shaft while in use. However, the deflection of specials that have been order longer, can be a concern, especially at the maximum length
When a very long Tube Sheet Pit Gauge is in use, the operator must be completely mindful of keeping the Contact Surface flat against the work-piece. Due to the flexibility of the long shaft, the operator will need to be inventive to block or hold the Contact Surface up against the target area
