Stem dia. 3/8″, #4-48 UNF Thread Yellow Dial Face
Metric Dial Indicator
Dial indicators are precision measuring instruments used in various industries and applications for precise measurements and quality control purposes. They are highly versatile and offer reliable and accurate readings for dimensional measurements. This comprehensive product description aims to provide a detailed overview of dial indicators, their features, applications, and benefits, helping users make informed decisions when selecting the appropriate dial indicator for their specific needs.
A dial indicator, also known as a dial gauge or plunger dial, is a precision measuring instrument used to measure small linear distances, displacements, and deviations. It consists of several key components that work together to provide accurate measurements.
Housing: The dial indicator is housed in a sturdy casing that encloses and protects the internal components. The housing is typically made of metal or plastic, ensuring durability and stability during measurements.
Plunger: The plunger is a spring-loaded rod that extends and retracts based on the measurements being taken. It is designed to move smoothly and provide consistent readings. The plunger can be pressed against a surface or object to measure deviations or displacements.
Rack and Pinion Mechanism: The plunger is connected to a rack and pinion mechanism that converts the linear motion of the plunger into rotary motion. As the plunger moves, it rotates the dial face and needle, indicating the measurement on the calibrated scale.
Dial Face: The dial face is a circular disc that displays the measurements. It is typically marked with a scale calibrated with evenly spaced markings. The dial face is designed for easy readability and precise interpretation of measurements.
Needle or Pointer: The needle or pointer is attached to the rack and pinion mechanism and moves along the dial face as the plunger is extended or retracted. The needle points to the specific measurement on the scale, providing a visual indication of the measured value.
Mounting Options: Dial indicators come with various mounting options, such as lug back, stem, or dovetail mounts. These options allow users to attach the dial indicator to different types of fixtures, machines, or stands, providing flexibility and convenience during measurements.
Dial indicators offer a range of features and specifications to meet different measurement requirements. These include:
Measurement Range: Dial indicators are available in various measurement ranges to accommodate different applications. The range indicates the maximum distance the plunger can move to measure deviations or displacements accurately.
Resolution: The resolution of a dial indicator refers to the smallest increment it can measure. It determines the level of precision and accuracy of the measurements. Dial indicators can have resolutions as fine as 0.001mm or 0.0001 inches, allowing for precise and detailed readings.
Accuracy and Repeatability: Dial indicators are known for their high accuracy and repeatability, ensuring consistent and reliable measurements. They are designed to provide precise readings within specified tolerances, making them suitable for quality control and inspection tasks.
Additional Features: Some dial indicators offer additional features, such as a bezel lock to secure the dial face in a fixed position, a rotating dial for easy zero adjustments, or a shockproof design to withstand harsh working conditions.
Section 1: Overview of Dial Indicators
A dial indicator, also known as a dial gauge or plunger dial, is a mechanical device used to measure small linear distances, displacements, and deviations. It consists of a needle or pointer mounted on a spring-loaded plunger that moves along a calibrated scale, displaying measurements in units such as inches or millimeters.
Dial indicators typically comprise a housing, plunger, rack and pinion mechanism, dial face, needle or pointer, and a mounting system. The housing encloses the internal components and provides stability. The plunger extends and retracts based on the measurements being taken. The rack and pinion mechanism translates the linear motion of the plunger into rotary motion of the dial face and needle, enabling accurate readings.
1.3 Measurement Range and Resolution:
Dial indicators offer a wide range of measurement capabilities, with variations available for different measurement ranges. The resolution, or smallest increment, of measurement varies depending on the specific dial indicator model, with some providing resolution as fine as 0.001mm or 0.0001 inches.
