Tubular Inside Micrometer Sets100-1200mm
There are several inside micrometer designs, though the most common are tubular- and caliper-type micrometers. A tubular inside micrometer consists of a cylindrical tube that may be placed in the inner diameter of a hole or ring to precisely determine the diameter, or between two parallel surfaces to measure the distance between them. Once the tubular micrometer is in place, he inside micrometer is the most direct measuring tool used for inspection (Figure 1). The total length of the inside micrometer is itself the overall length being measured. The inside micrometer is a much more accurate
measuring tool for inside measurement than the caliper.
The inside micrometer is almost always purchased as a set. The only way to use the inside micrometer over a range of sizes is by using extension rods. Only one
micrometer head is needed, along with extension rods, to cover a broad range of measurements. Tubular style extension rods are available in the intermediate to extended length, while solid extension rods are used for ranges of up to approximately 32 inches
here will usually be a way to extend the tube until it contacts both sides of the inner diameter of whatever is being measured. Caliper-type micrometers generally feature one stationary and one movable caliper mounted on a tube, with the ability to adjust the movable caliper out along the length of the tube to make a measurement.
