Portable gauging refers to the process of measuring and inspecting various parameters or dimensions using handheld or portable devices. There are several types of portable gauging instruments available for different applications. Here are some common types:
- Calipers: Calipers are versatile handheld gauges used for measuring distances or dimensions between two points. They come in various types, including Vernier calipers, dial calipers, and digital calipers, offering different levels of accuracy and precision.
- Micrometers: Micrometers are precision gauges used to measure dimensions with high accuracy. They are commonly used for measuring small distances, thicknesses, or diameters. Micrometers can be external (measuring outside dimensions) or internal (measuring inside dimensions).
- Depth Gauges: Depth gauges are used to measure the depth of holes, slots, or recesses. They typically consist of a scale or digital display and a probe that is inserted into the measurement area to determine the depth.
- Height Gauges: Height gauges, also known as height indicators or height comparators, are used to measure vertical distances or heights. They are commonly used in machining and manufacturing processes to ensure precise height measurements.
- Thread Gauges: Thread gauges are used to measure the pitch diameter, thread profile, or pitch of threaded components. They include tools such as thread pitch gauges, thread plug gauges, and thread ring gauges.
- Surface Roughness Testers: Surface roughness testers are portable instruments used to measure and evaluate the roughness or texture of a surface. They provide information about the surface finish, such as roughness average (Ra) or peak-to-valley height.
- Ultrasonic Thickness Gauges: Ultrasonic thickness gauges are used to measure the thickness of materials using ultrasonic waves. They are commonly used in industries such as metalworking, corrosion inspection, and material testing.
- Feeler Gauges: Feeler gauges consist of a set of thin metal strips or blades of varying thicknesses. They are used to measure gaps, clearances, or alignment tolerances in various applications, such as automotive maintenance or machinery setup.
These are just a few examples of portable gauging instruments. The specific type of gauging instrument used will depend on the measurement requirements and the parameters being inspected. It’s important to select the appropriate instrument for the specific application and ensure proper calibration and maintenance for accurate and reliable measurements.
