Gauges And Diagnostic Devises

Gauges are used to measure different types of objects having various sizes, shapes, and thicknesses, the gap in space, diameter of materials, or pressure of the flow. Specific types of gauges are used to measure each parameter. Gauges are classified into eight types, they are: Plug gauge.

What is a Gauge?

A gauge is an important measuring device in the field of design engineering. It is a device used to provide certain dimensional information, according to a specified standard or system.

Some gauges are meant to measure the size of the object. But, most gauges are mainly used to specify if the dimensions of the measuring object are less or greater than defined standards that are within the tolerance range. Gauges can be operated electrically or mechanically.

They are generally considered as fixed-type or deviation-type instruments. Fixed-type gauges are designed to showcase if a given dimension is larger or smaller than the standard. They are usually made of soft steel, hard steel, or glass. To prevent rub-down, fixed-type gauges are chrome-plated or tungsten-carbide coated. Now let us know more about the various types of gauges.

Types of Gauges

Gauges are used to measure different types of objects having various sizes, shapes, and thicknesses, the gap in space, diameter of materials, or pressure of the flow. Specific types of gauges are used to measure each parameter. Gauges are classified into eight types, they are:

  • Plug gauge
  • Ring gauge
  • Taper gauge
  • Snap gauge
  • Feeler gauge
  • Thread gauge
  • Form gauge

Caliper gauges

Now let us know in brief about each type of gauge.

Plug Gauge

A plug gauge is a fixed gauge that is used for measuring the shape and size of a hole. A plug gauge comes with different diameters. They are helpful to measure the inside diameters of drilled holes or holes that are machined into a manufactured part, component, or assembly. While measuring the inside diameter of the hole, aids in analyzing if the dimension of the hole falls under specified dimensional tolerance. These gauges are made of wear-resisting steel.

To check the lower limit of the hole, No-go gauge is used, and to check the upper limit of the hole, Go-plug gauge is used. The plain plug gauges are the double-ended type.
