Strain Gauge Set with Digital Dial Indicator (U.S./Metric)
Strain Gauge Set is used to yield precise physical measurements of strain in materials or structural components under load, relative displacements in structures, opening or closing of cracks, shrinkage of the concrete block during curing, and similar applications. The anodized aluminum alloy instrument frame adjusts for measuring at 2, 4, 6, 8, or 10in spacing (5, 10, 15, 20, 25cm for metric) of Punch Bar and Invar Master Bar used.
Strain Gauge Set with Analog Dial Indicator (U.S. units) has an analog dial indicator unit of measure in U.S. units and has 0.0001in graduations, maximum travel of 0.4in, and 0.3in range of strain measurement.
Strain Gauge Set with Analog Dial Indicator (Metric units) has an analog dial indicator units of measure is metric units has 0.002mm graduations, maximum travel of 10mm, and a 7.6mm range of strain measurement
Strain Gauge Set with Digital Dial Indicator (U.S./Metric units) has digital indicator units of measure that can switch between U.S. and metric units with 0.0001in or 0.001mm graduations. The digital dial indicator has a data output interface and has a battery life of 5,000 hours.
The Storage Case includes slots for the Invar Master Bar for Strain Gauge and Strain Gauge Punch Bar – both are required items of the Strain Gauge Set sold separately, and available in Imperial or Metric models. Master Bar has stainless steel seat inserts to check gauge space settings. Punch Bar has one fixed point and one moveable point and is used to accurately locate the position of brass Inserts in the specimen.
