Calipers are measuring instruments used to measure the dimensions of objects, such as thickness, diameter, or distance between two points. There are many types with different characteristics and uses. These tools are important in many industries, such as manufacturing, engineering, and handyman work.
Main components of Calipers
1. Jaw (scissors) The part that looks like scissors, which is used to measure the size of objects. There are two sides: the inner jaw (for internal measurement) and the outer jaw (for external measurement).
2. Scale (scale) The size is clearly divided so that the user can read the value obtained from the measurement.
3. Depth Probe (depth measuring tube) is used to measure the depth of holes or cavities.
4. Locking Mechanism (locking mechanism) is used to maintain the measured value during the reading.
5. Digital Display (digital screen) In digital calipers, there is a display screen that helps to read the value quickly.
How Calipers Work
Calipers work by measuring the distance between the two jaws. The user opens the jaws wide enough to place the object in them. Then, it will lock and read the value displayed on the scale or screen in the case of digital calipers.
1. Setting before measuring Make sure there are no obstacles. And the object to be measured is in the correct position.
2. Measuring Place the object between the scissors and lock it.
3. Reading the value Read the value obtained from the scale or digital display.
Types of Calipers
1. Vernier Calipers Use accurate readings using a vernier scale. Often used in measurements that require high accuracy.
2. Digital Calipers have a digital display that makes reading easy and fast.
3. Dial Calipers use a dial to read values. There is a needle that shows the measured value.
4. Depth Calipers are designed to measure the depth of holes or cavities.
5. Inside Calipers are used to measure internal dimensions, such as pipe sizes.
6. Outside Calipers are used to measure external dimensions, such as the diameter of objects.
Usage of Calipers
Calipers are used in many industries, such as
1. Manufacturing industry Used to check the size of parts to ensure that they are of standard sizes.
2. Maintenance Used to check the size of equipment to be repaired.
3. Research and development Used in scientific experiments to measure the size of different materials.
4. Quality control Used to check the quality of products on the production line.
Advantages of Calipers
- High accuracy Can measure in millimeters or less, which makes it an appropriate tool for measurements that require high accuracy.
- Wide range of applications Can be used to measure in many forms, such as external, internal, and depth measurements.
- Easy to carry, small size and light weight make it easy to use in various places.
Disadvantages of Calipers
- Sensitivity to calibration If not properly calibrated It may affect the accuracy of the measurement.
- Easily damaged If dropped or hit It may cause distortion.
- Complexity of use The user must have knowledge to read the value correctly.
Calibration of Calipers
Calibration of Calipers is an important step to ensure that the tool can measure accurately. The calibration steps can be done as follows:
1. Using standards Use high-precision standards as a comparison.
2. Check for abnormalities Check if there are any abnormalities in the tool.
3. Record values Record the values obtained from calibration to track performance.
Summary
Calipers are important tools in high-precision measurement work. Choosing the right caliper and calibrating it correctly will help make the measurement accurate and reliable, which is important in all industries related to production, quality control, and research.
