ITEM 1 - BASIC BENCHMARK GAUGE SET
Benchmark gauges are specifically designed for conducting on-line checks of turbomachinery alignment. The basic benchmark gauge set consists of a telescoping column with an electronic digital readout, six extensions, a 25" standard, and an inclinometer. The digital readout uses a single 1.5 volt size SR44 battery (type and size commonly used in electronic calculators and cameras). Expected battery life is 2 years. A spare battery is furnished.
The benchmark gauge itself is spring-loaded with spherical seats at either end to match the spherical benchmarks that are mounted on the equipment. The gauge is self-supporting when placed between pairs of benchmarks. The range of the benchmark gauge, without extensions, is 25" to 30". The six extensions give the tool a total range of 25" to 60" in increments of 0.001".
The standard and the extensions are constructed of Invar. The low coefficient of thermal expansion of this material greatly reduces measurement errors resulting from thermal expansion of the tool itself. The standard and the extensions are manufactured to an overall accuracy of 0.001" in length. Exposed portions of the tool, including spherical seats, are stainless steel.The gauge set is packaged in a durable ABS plastic case. Overall dimensions 38" x 14" x 5", weight 28 pounds.
ITEM 2 - EXTENSION SET
Set of 4 extensions for item 1 covering a measurement range of 60" to 80". Furnished in a tubular plastic case. 16 pounds (7 kg).
ITEM 5 - SHORT RANGE BENCHMARK GAUGE SET
For conducting hot alignment checks on smaller equipment. Same construction as item 1, but with a reduced measuring range. The range of the benchmark gauge is 13" to 16". The six extensions give the tool a total range of 13" to 34". Case dimensions 24" x 14" x 5". 20 pounds.
ITEM 6 - EXTENSION SET
Set of 6 extensions for item 5 covering a measurement range of 34" to 52". Furnished in a tubular plastic case. 20 pounds.
