MaraMeter. Indicating Measuring Instruments for Outside Dimensions Wire Insulation Thickness Gages 57B For checking wall thickness of wire insulation and other small-diameter tubular parts Features Using the basic design of the Model 57B-13 (Model 57B-13M Metric) Gage the lower contact is PT-103 1.10 mm .043" diameter rod mounted horizontally. The upper radiused contact is a chisel contact in line with the rod. By slipping tubular parts onto the lower contact the gage can measure the thickness of the wall of the tube. A 10 gram auxiliary weight (WT-3) on the Indicator provides a total dead-load weight of 25 grams. (Replacement lower rod PS-43) 57B-13 Technical Data Order no. Metric 57B-13M Inch 57B-13 Capacity mm inch 0-2.5 0-.10" Options XLI-57B-13 PT-2245 Description Dial Indicator readout with 7.6 mm .30" sensitive range and 0.01 mm .0005" grads. Max m XL Digital Indicator with 25 mm 1" range and 0.001 mm .00005" resolution (Model XLI-50002). 0.050 mm .02" diameter Pin Lower Contact Assembly Measuring Compressible Materials Compressible materials such as paper plastics rubber or fabrics must be measured under controlled conditions. Many materials have measurement standards specified by A.S.T.M. U.L. or other industry standards organizations. Measurement standards specify dead load weight upper and lower contact configurations and Indicator resolution. Series 57B Gages are easily modified to meet most of these industry standards. Mahr Federal has on file designs for the measurement of paper latex foam rubber sponge rubber vulcanized rubber asbestos tape and cloth sheet and roll felt and many other materials. When inquiring specify A.S.T.M. Specification Number if possible.
