3:1
Mechanical dial gauges
Using the mechanical transmission system, the linear displacement of the measuring rod is converted into the angular displacement of the pointer on the circular dial, and the reading is measured by the dial
appliance:
Note: The measuring instrument may also have a revolution indicating device, such as: revolution pointer or rod displacement pointer:
4 Design features
4:1 Overview
The overall design and process should make the performance of the indicator meet the requirements: Unless otherwise specified by the manufacturer, comply with the requirements of this standard:
The design and rigidity of the mechanical indicator should ensure that the free movement of the measuring rod is not affected by the installation device, and can achieve the necessary for stable installation
degree: If other installation methods are used, such as the lugs installed on the back plate, the design and rigidity should meet the performance requirements without being damaged:
