What Is Telescopic Gauge & Who Uses Them For Their Work? A telescopic gauge can be termed as an indirect measuring device. The technician using the device would position the head inside holes or openings and extend to touch the base or wall. The device is then removed from the hole and the size of the extended header is used to know the internal radius of the hole, with the help of other measuring equipment with a micrometre or a vernier calliper.
Generally, mechanics who work with pitch gauge would use this telescopic version while working with machinery that needs to measure the interior radius or calculate the circumference of a hole or pipe. The other application of the gauge is to measure the interior radius of the bore or a cylinder in which the pistons extends and retract. For internal combustion and diesel engines, to work properly would need a tight cylinder, in which the air cannot pass out of the cylinder when the piston is extended, compressing the gases. For proper functioning, the size of the piston head must match with the radius of the cylinder. In such cases, the well-calibrated gauge is required to get maximum output. It is important for the technician to choose the correct size gauge. The size, in this case, refers to the distance the telescopic rods can measure when they are closed up and fully extended. The device does not have any measurement increments of its own, so they need to be used along with other devices. The professionals would be able to use the device correctly. If they are not handled properly, the device would not give a proper reading. In a few cases, it would not last long as well. It is important to use top-quality equipment, as they would help in providing the correct measurements. They reduce the chances of error significantly. These devices need to be calibrated from time to time to get error-free results.
