Metrology is a significant department of Mechanical engineering that deals with the measurement of a workpiece. Metrology is oftentimes called the science of measurement that depends upon two significant factors. The factors are time and quantity, which has to be measured by an engineer in order to ensure the precision of a workpiece. Every material […]
The Dial Indicator is a mechanical device that consists of pinions, gears or levers. By the means of a dial indicator precision of a workpiece can be measured by an engineer. Although it is working as a comparator also (Baxterand Meijer, 2017). Construction of a Dial Indicator: Construction of a Dial indicator changes regarding their […]
A comparator works on the relative dimension, which means it can measure the difference between basic dimensions with the actual dimension. Sigma comparator is one type of mechanical comparator developed by the Sigma Instrument Company, USA. Construction of Sigma Comparator: A Sigma Comparator is constructed by the following components, and those are: Plunger Knife Edge […]
Comparator is not a measuring instrument, it is a comparing instrument that means it can compare the measured value of a substance with its actual value. There are various types of comparators are available in the market, Johansson Mikrokrator is one of them. It is a mechanical type of simple comparator invented by C.F. Johansson. […]
Measuring instruments are the device which indicates the measured quantity into a broadly displayed information. A measuring instrument can directly show the measured value or it can show the equivalent value to known measure value of the same quantity. To do the perfect performance, an instrument should have some quality, here in this article we […]
