Machine Mounted Dimensional Indicators and Comparators
Description
Machine Mounted Dimensional Indicators and Comparators are precision instruments used to detect variations in specific distances. They amplify and display these variations on a dial, graduated scale, or digital display. These devices are essential for comparative length measurements, where they compare the actual length of a specimen to a reference length, showing any deviation from the nominal size.
Working Principle
The working principle of these indicators and comparators involves the linear movement of a precision spindle, which is then amplified and displayed. Mechanical comparators use a low friction mechanism to achieve high precision, while electronic comparators may use technologies like linear variable differential transformers (LVDTs) to sense displacement. These instruments are useful because they provide a high level of precision and can be used for the calibration of other gages, ensuring that measurements are accurate and reliable.
Applications
Machine Mounted Dimensional Indicators and Comparators are used in various applications, including the measurement of high precision ground parts. They are also employed in the calibration of other gages, ensuring that tools and components meet specified tolerances. Specific examples include measuring thread size, pitch, and serration, as well as determining wall thickness, depth, height, and other dimensional attributes.
Advantages over other Dimensional Indicators and Comparators
Compared to conventional dial or digital indicators, machine-mounted comparators offer better discrimination and lower range, making them suitable for high precision tasks. They have less span error and provide a higher level of precision, which is crucial for applications requiring meticulous accuracy, such as in the calibration of other gages and the measurement of high precision ground parts.
Limitations
One limitation of machine-mounted comparators is that they are not complete measuring instruments by themselves. They require additional devices to stage the object on a reference plane for accurate measurements. Furthermore, the precision of these instruments can be affected by operator skill, especially in systems that do not perform automated measurements.
Considerations
When considering the use of machine-mounted dimensional indicators and comparators, it is important to evaluate initial costs, operating expenses, and maintenance requirements. These instruments are generally durable and provide high accuracy, but they may require regular calibration and maintenance to ensure continued precision. Replacement costs can also be a factor, particularly for high-end electronic comparators that use advanced sensing technologies.
