4. Gauges
 A device used for measuring dimensions. A
device used to measure the distance between
two opposing sides of an object.

5. Inspection Gauges
 Inspection gauge is a tool used to check
product dimension with reference to its
maximum and minimum acceptable limits. It
is generally used to acceptable and non
acceptable product in mass production.

6. Types of Inspection gauges
 Calipers:
 They are normally of two types- inside and outside
caliper.They are used to measure internal and external
size (for e.g. diameter) of an object.
 Venire caliper:
 It is a precision tool used to measure a small distance
with high accuracy.
 Micrometer:
 It is a fine precision tool which is used to measure small
distances and is more accurate than the venire caliper

7.  Bridge gauge:
 Bridge gauges are used to measure the amount of
wear of Main engine bearing.
 Bore Gauge:
 A tool to accurately measure size of any hole is known
as bore gauge.
 Depth gauge:
 A depth gauge is used to measure the depth of a slot,
hole or any other surface of an object. It can be of
scale, dial or digital type.

8. Telescope Gauge:
 There is a range of gauges that are used to measure
a bore's size, by transferring the internal dimension
to a remote measuring tool.

9.  Limit Gauge or Go/No Go gauge :
 refers to an inspection tool used to check a work-
piece against its allowed tolerances.
Go/noGo gauge

10.  Dial Gauge:
 Dial gauge is utilised in different tools as I stated
before and can be separately used to measure the
trueness of the circular object.
 Snap gauge
 A snap gauge is a form of Go/no go gauge . It is a
limit gauge with permanently or temporarily fixed
measurement.

11. Dial Gauge

12. Snap Gauge

13. Thread Pitch Gauge:
 It is also known as screw pitch gauge or pitch gauge. Use
to measure pitch or lead of screw thread.

14. Profile Gauge:
 Profile gauge or contour gauge is a tool for recoding
the cross-sectional shape of a surface.
Profile or contour gauge

15. Ring Gauge:
 Ring gauge is a cylindrical ring of steel whose
inside diameter is finished to gauge tolerance and is
used for checking the external diameter of a
cylindrical object. It is also a type of go/ no go
gauges.

16. Feeler Gauge:
 A feeler gauge is a tool used to measure gap
widths. Feeler gauges are mostly used in
engineering to measure the clearance between two
parts.

17. Temperature Gauge:
Temperature gauges works ar expansion principle. These
gauges are operates with a helical or spiral tube & an
expansion gauge contains a temperature sensor.
Commonly used in foundry & automobile industries.

18. Wire gauge:
 Wire gauge use measure of how large a wire is, either
in diameter or cross- sectional area.This determines the
amount of electric current a wire can safely carry.

19. Bore Gauge:
 Bore gauge is a device which used to measure holes
accurately.
 Types:
 Point to point bore gauge
 Three point bore gauge
 Two point electronic plug gauge
 Dial bore gauge

20. Bore gauge:

21. Plug gauge:
 A plain plug gauge used to check the size of a hole; the
green end is the go, and the red end is the no go.
Plug gauge

22. Tide Gauge:
 It is also called as marigraph or mareograph.Tide gauge
is a device used to measure the sea level changing water
condition.
