These are widely used for general-purpose measurements and are available in different lengths of lever arms to accommodate various measurement requirements.

Plunger-Type Dial Indicators

Plunger-type dial indicators are specifically designed for measuring linear displacement or variations in depth. They have a spring-loaded plunger that extends and retracts. These indicators are frequently used in bore gauges, tool setting, and fixtures.

Dial Test Indicators

Dial test indicators, also known as test indicators, are small and highly precise instruments used for making fine measurements. They are often employed in machining, tool setup, and alignment tasks. Dial test indicators typically have a smaller range of motion and are sensitive to small variations in position.

Continuous Reading Dial Indicators

Continuous reading dial indicators, as the name suggests, provide a continuous reading throughout their range. They are ideal for applications where you need to monitor changes in position over a broad range, and they often have a larger dial face to accommodate this.

Dial Depth Gauges

These are specialized dial indicators used to measure the depth of holes or slots. They typically have a rod with a contact point that is inserted into the hole or slot to measure its depth. Dial depth gauges are common in machining and manufacturing for ensuring hole depths are within tolerance.

Back-Plunger Dial Indicators

Back-plunger dial indicators are designed to be inserted into narrow openings or tight spaces. They have a plunger that extends from the back of the indicator, making them suitable for measuring inside holes, bores, and other confined spaces.

Interchangeable Contact Point Dial Indicators

These indicators allow users to change the contact point to suit specific measurement requirements. This flexibility is useful when measuring different features or part geometries without the need for multiple indicators.

Magnetic Base Dial Indicators

Magnetic base dial indicators come with a magnetic base that can be attached to a ferrous surface, allowing for hands-free measurement. They are commonly used in machining, setup, and alignment applications.

Fractional Dial Indicators

Fractional dial indicators are designed with fractional graduations on the dial face, making them suitable for tasks where fractional measurements are preferred, especially in the United States. These indicators can be helpful in applications where metric measurements are not commonly used.

Dial Comparators

Dial comparators are specialized dial indicators used for comparing the dimensions of two objects. They often consist of two indicators, one for measuring the reference or master part and another for measuring the workpiece. Dial comparators are useful in gauging part tolerances and verifying dimensions.

Applications and benefits of Dial indicators

Some common applications and benefits of dial indicators:

Applications:

Quality Control and Inspection

Dial indicators are frequently used in quality control processes to verify the accuracy and precision of manufactured parts. They help ensure that components meet specified tolerances and quality standards.

Machine Setup and Alignment

In manufacturing and machining, dial indicators are used to set up machines and ensure the alignment of workpieces, cutting tools, and machine components. This is crucial for achieving precise and accurate machining results.
