What is the difference between dial gauge and dial indicator?
Dial gauge also available with a large diameter for easy reading. If you want to measure the back of the body use the Back Plunger type dial indicator. Digital type dial gauge is more accurate than Dial display. Dial indicator comes with different contact point vary according to the application.
How accurate are dial indicators?
Dial indicators translate small linear distances into rotational movement to measure dimensions to 4.000″, with accuracies up to 0.0001″. They are typically fixed to a magnetic base or other Starrett fixture.
What is a dial gauge indicator used for?
Dial indicators are one of the primary measuring tools used in precision engine building. They are typically used to measure deck clearances, crankshaft thrust and straightness, lifter travel and other measurements that involve the distance between two surfaces or small amounts of component travel.
What is the range of a dial indicator?
0.25 mm to 300 mm
Dial indicators typically measure ranges from 0.25 mm to 300 mm (0.015in to 12.0in), with graduations of 0.001 mm to 0.01 mm (metric) or 0.00005in to 0.001in (imperial/customary).
What is least count of dial gauge?
0.01 mm
The typical least count that can be obtained with dial indicators is 0.01 mm. It measures the measurement in the range of 0.25 to 300 mm.
How do you calibrate a dial gauge?
2.1 Position the dial indicator on the dial indi- cator comparator stand. Adjust the dial indicator in such a manner that when the contact point of the spindle rests firmly on the comparator stand base, the hand registers 0.000. 10.5. 2.2 Record the zero reading on the dial indicator calibration form.
How many types of dial indicators are there?
There are two main types of dial test indicator. This type of instrument relies upon a rack and pinion mechanism to change the linear (straight-line) movement of the plunger into rotary motion for the pointer.
What are 2 types of dial indicators?
In the most general sense, there are two types of indicators commonly used in shop environments: test indicators and drop indicators.
