Lever dial indicators, also known as test or finger indicators, are precision measuring devices used to accurately determine small linear distances or variations. They are particularly useful for measuring surface variations, alignment inspection, and defining the runout or concentricity of rotating parts. Level dial indicators are widely used in packaging, engineering, design, and manufacturing applications where precision is paramount.
What Do Level Dial Indicators Measure?
Unlike standard dial indicators, where the measuring needle moves directly in line with the measurement, lever dial indicators utilise a lever mechanism to magnify small movements of the contact point. A small, uniquely shaped tip that contacts the surface being measured. The contact point is connected to a lever that pivots on a fulcrum. A slight movement of the contact point provides a more significant angular movement of the lever. The lever's motion is then converted into a rotary motion of a pointer on a circular dial through a system of gears. The dial is progressed with precise markings, and the pointer shows the measured value.
What Benefits Do Our Innovative Lever Dial Indicators Offer?
- Ability to measure tiny variations, often down to 0.001mm or 0.0001 inches.
- Used in different orientations and for measurements in hard-to-reach areas.
- Their compact size makes them perfect for use in confined spaces.
- The dial offers a clear and easy-to-read display of the measured value.
What are the Available Lever Dial Indicator Types?
- Horizontal: The most typical type, with the dial face horizontal.
- Vertical: Used for measurements where the dial face needs to be vertical.
- Universal: Can be modified for various orientations.
Where Can Lever Dial Indicators Be Used?
- Machining: Inspecting the precision of machine parts and machine tool setups.
- Quality Control: Analysing parts for dimensional accuracy and surface finish.
- Tool and Die Making: Aligning and setting up tools and dies.
- Automotive Repair: Examining runout of brake rotors and other rotating parts.
Overall
Lever dial indicators are valuable instruments for obtaining precise measurements in various manufacturing, quality control, and inspection applications. Their sensitivity, versatility, and ease of use make them essential for many professionals and applications.
