Dial Indicator

Dial indicators are precision measuring tools commonly used in various industries, including manufacturing, engineering, and automotive. They are part of the supply class "Measuring Tools" and specifically fall under the category of "Craftsmen's" in the supply group "Measuring Tools."

A dial indicator consists of a dial face with a needle or pointer that moves in response to small changes in measurement. It is typically mounted on a stand or held by hand and used to measure the relative position or movement of objects with high accuracy.

The main components of a dial indicator include:

1. Dial Face: This is the circular face of the indicator that displays the measurements. It is marked with graduations or divisions for precise readings.

2. Needle or Pointer: The needle or pointer is attached to a spindle and moves in response to changes in measurement. It indicates the measurement on the dial face.

3. Spindle: The spindle is the part of the indicator that moves in and out to measure the distance or displacement. It is connected to the needle or pointer.

4. Bezel: The bezel is the outer ring of the dial face that holds the crystal or glass cover in place. It may also have a rotating feature to set or zero the indicator.

5. Stem: The stem is the cylindrical part that connects the dial face to the base or mounting point. It provides stability and allows for adjustments.

Dial indicators are commonly used for various applications, such as:

- Measuring small distances or displacements with high precision.
- Checking the alignment or runout of machine parts.
- Monitoring the movement or deflection of structures.
- Verifying the flatness or parallelism of surfaces.
- Setting up machinery or equipment to specific tolerances.

Overall, dial indicators are essential tools for accurate measurements and quality control in various industries.
