Difference between Gage and Gauge A gauge is a measuring instrument that reproduces a quantity in a fixed form. Its points are as follows. ① itself directly reproduces the unit of measure, that is, the nominal value of the gauge is the actual size of the unit of measure, such as the block itself reproduces the unit of length. Cast iron platform ② In the structure of the general lack of measurement mechanism, no indicator or moving parts. Such as the measurement block is only a physical reproduction of the unit of measure. ③ due to the lack of measurement mechanism, such as not relying on other measuring instruments, can not directly measure the measured value. For example, the block should be equipped with a kilowatt-hour meter and an optical meter. Therefore, it is a passive measuring instrument. Marble platform Gauge is a measuring instrument that converts the measured quantity into an indication or equivalent information that can be seen directly. Its points are as follows. Level (1) itself is not. The unit quantity is not the low reproduction, but the indication value or equivalent information obtained through conversion. Such as display value, digital, pulse signal, sound and so on. The conversion in the definition is a key point. For example, if the indicator value of a percentage meter is 0.01mm, the needle has a large displacement, which is realised by an amplifying mechanism. These values do not in themselves reproduce the unit value, but only the magnitude of the measured value. Pendulum Gauge ②There is a measuring mechanism in the structure, and there is an indicator or movable measuring elements such as a pointer and a cursor. Gear Runout Gauge ③ can directly measure the measured value of the object, is an active measuring instrument. In general, the gauge structure is simple, easy to operate, easy maintenance, low price, accuracy to meet the general measurement requirements. Gauge has the advantages of high sensitivity, high precision, small measuring force, but the structure is complex, expensive, and the use of environmental conditions require high. Plug & Ring Gauge
