Granite measuring tools, measuring tool measuring tool, but the difference you know? Come and see our small make up what is said.
Granite measuring repetition measurement of the value in the form of fixed appliance. Its characteristics are as follows:
1. Repetition itself directly the value of the unit, the granite measuring tool measuring unit of nominal value is the actual size of the value, such as gauge block itself resembles the measuring unit.
2. No measuring general agency in the structure, there is no indicator or moving parts. Such as block gauge just repetition unit quantity of a material object.
3. Since there is no measurement institutions, such as do not rely on other with measuring instruments, cannot be measured directly by the measured values. For example to with interferometer for gauge block measurement, optical meter. So it is a kind of passive measurement apparatus.
Measuring tool is to replace the quantity being measured with direct observation or equivalent information indicating value of measuring instruments. Its characteristics are as follows:
1. Itself is not the unit quantity is worth repetition, but indicated value or equivalent equivalent information is obtained by conversion. As shown, digital, pulse signal, sound, etc. Definition of the conversion is a key, such as the dial indicator indicating value of 0.01 mm, the pointer is larger displacement is achieved by amplification mechanism. The indicated value itself can't emersion unit value, just expressed by measuring the value of the size.
(2) on the structure of measuring mechanism, a indicator or movable measurement components, such as a pointer, the cursor.
3. Can be directly measured by the value of the object, is a kind of active measuring instrument.
Granite measuring tool and measuring tool is the difference between a share here, overall measuring tool is easy to use, simple, accurate, convenient maintenance and low price, the precision can meet the requirements of general measure, and instrument, its requirement is relatively high, structure complex, expensive, when using high requirements on the environment.
