What is Dial Gauge?

Dial Gauge is also called Dial Indicator. Dial Gauge is a device or a component or an instrument that uses the Numbers, Indicators, and the internal mechanism to give a standard measured value of a particular job or a component. In the field of Mechanical, dial gauge plays a very prominent role and use in the Production, Quality departments mostly.

Use of Dial Gauge:

The use of dial gauge is vast and prominent in the mechanical tool rooms, and quality checking. The use of dial gauge is as follows:

  • The dial gauge is used to measure the distances in few components.
  • The dial gauge is used to measure the run-outs of a machine part and machining components to maintain accurate measurements.

Dial Gauge Least Count:

Dial gauge Least Count can also call as dial indicator least count. The Least Count is the minimum measurement that an instrument can able to measure any component and every measuring instrument (vernier caliper, micrometer, pressure gauge, etc) does consist of the least count to choose its field of application. So, dial gauge is a Special Case Instrument and Precision Instrument that we can measure up to a value of 0.001 mm so the dial gauge least count (or dial indicator least count)is 0.001 mm.

According to the dial gauge least count value, we can say that the dial gauge is a highly accurate measuring device that other instruments cannot.

Main Components of Dial Gauge:

Dial Gauge is an analogue type and the indicator is used to show the value of the measured component so due to the usage of indicator, this device is also called the dial gauge indicator or dial indicator. So, the dial gauge or dial indicator requires a particular set up and components for its working, therefore the main components of dial gauge are as follows:

  • Probe
  • Gear or Pinion Gear
  • Indicator.

Dial Gauge Working:

Dial gauge working is analogue and the responses can be found by the indicator. Therefore the dial gauge indicator movement depends upon the probe and the gear. The Probe can be called Plunger; it is a sensitive and flexible mini rod type component whereas, it can move up and down (to and fro motion) when it is placed on the job.

To measure the value of the particular component, the probe of the dial gauge should gently move upon the component, due to the probe movement the gear inside the dial gauge will rotate.

We can observe the Rack and Pinion mechanism whereas; the Probe acts as Rack and Gear as Pinion (we can observe in the image). When the probe is moved upward direction, due to the connection of probe and gear, the gear will rotate. The indicator of the dial gauge is fixed to the Pinion gear and due to the pinion gear movement, the indicator will rotate, such movement is the response that we want to find out.

Dial Gauge Application:

As we read that the dial gauge application is vast, and used in tool rooms, machining places and the dial gauge is also used at,

  • Dial Gauge used for high accuracy and they are used for measuring the angles of the tapered components at laboratories mostly.
  • Dial Gauge used for checking the run-outs of the shafts.
  • Dial Gauge used for the calibration of the machines, slip gauges, etc.
  • Dial Gauge used for the Quality Departments and tool rooms for acceptance of the tools or components.

So, these are the dial gauge application in the mechanical field; in addition to these, the dial gauge is used for testing the roughness of the surfaces.

Conclusion:

Dial Gauge or Dial Indicator is a sensitive and high accurate gauge, due to its sensitiveness they need to be handled very carefully and store at still places. As it is highly sensitive, the dial gauge is costly. Its importance is very high and vast in the mechanical field for high precision tools. Handling of the dial gauge needs special education and special observation too. At most, the dial gauge is one of the important and chief devices that can be used.
