Precision instrument
As precision instruments are measuring devices or machines referred to the high resolution achieved with an exceptionally small position or measurement error . In order to guarantee the precision, they have to meet other criteria, above all
- high mechanical stability
- Sufficient moisture and temperature resistance within their area of application
- good reproducibility of your results ( measured values , manufacturing tolerance, etc.).
Types of precision instruments and machines
Some of the important types of precision instruments include:
Measuring device
Devices of various types fall into this category, for example
- Measuring devices for mechanical engineering (micrometers, dial gauges, etc.)
- electrical high-resolution digital multimeters with very small error limits
- optical laboratory measuring devices such as interferometers
- geodesic theodolites and tachymeters
- astronomical telescopes
- Precision balances
Machine tools
Among the tools are of high precision
- Precision lathes
- CNC lathes
Nautical and military equipment
- GPS and Doppler receivers
- Double gyro compass and gyro theodolite
- Precision approach radar
- Precision weapons
