Universal Length Measuring Machine is an instrument designed to measure the length of objects in a wide range and size with high accuracy and wide measuring capabilities. This type of instrument is important in quality control and calibration processes in many industries.
Range
The measuring range of a universal length measuring machine refers to the range that the instrument can measure, from the minimum value to the maximum value that the instrument supports. Choosing the right measuring range is important to ensure the highest measurement accuracy.
- Measuring range of the instrument Some instruments can measure in a wide range, such as from millimeters to meters, depending on the design and function of the instrument.
- Adjusting the measuring range Universal length measuring machines often come with a measuring range adjustment system that can be adjusted to suit the size of the object to be measured.
Expanded Uncertainty
Expanded uncertainty is the calculation of all uncertainties that may occur in the measurement process, which increases the confidence interval that helps to ensure the accuracy of the measurement.
- Uncertainty calculation Use data from the calibration and analysis of the instrument to calculate the expanded uncertainty. It may use accepted criteria or standards.
- Uncertainty management Accurate measurements can reduce expanded uncertainty through regular maintenance and calibration.
Reference Standard
Reference standards It is an instrument used to compare and verify the accuracy of universal length measuring instruments to ensure that the measurement is accurate and reliable.
- The role of reference standards Reference standards help to compare measurement results and calibrate instruments to meet the specified standards.
- Examples of reference standards Length standards calibrated by reliable organizations, such as calibration by international standards.
Method
The method used in measurement refers to the processes and techniques used to perform measurements, which are important in ensuring accurate results.
- Selection of measurement methods The method used can include the use of various sensors, such as contact sensors, optical sensors, or digital sensors.
- Calibration and verification The measurement method must be calibrated and verified regularly to provide accurate results.
Equipment
The equipment used in universal length measuring instruments is diverse and has different functions. It may include:
- Contact measuring instruments, such as digital dial gauges, butterfly-wing length measuring instruments
- Non-contact measuring instruments, such as laser scanners, optical length measuring instruments
- Maintenance Maintenance and calibration of equipment are important to maintain the accuracy and life of the instrument.
Universal length measuring instruments are important tools for measuring lengths with precision and variety. Understanding the measurement range, extended uncertainty, reference standards, methods, and equipment is essential to using this instrument.
