Moore & Wright MAW42003 Dial Indicator

The Moore & Wright MAW42003 Dial Indicator is a precision measurement instrument designed for accurate detection of linear displacement, surface irregularities, and alignment verification in industrial and laboratory settings. Its compact yet robust construction makes it suitable for use on workbenches, machining centers, and quality control stations.

Key Features

• Resolution: The device offers a fine resolution of 0.01 mm, allowing technicians to detect minute variations in component geometry.
• Travel Range: With a maximum dial travel of 0.8 mm, the indicator can accommodate a wide range of measurement tasks without sacrificing accuracy.
• Dial Face: The large, high‑contrast dial face enhances readability under various lighting conditions, reducing operator fatigue and error.
• Robust Housing: Constructed from durable materials, the indicator withstands repeated use in demanding production environments while maintaining calibration integrity.
• Easy Mounting: The standard mounting interface allows quick attachment to a variety of fixtures, including V‑blocks, jigs, and test stands.

Applications

The MAW42003 is ideal for tasks such as:

• Verifying the flatness or roundness of machined parts.
• Measuring runout and wobble in rotating components.
• Checking alignment between mating surfaces during assembly.
• Monitoring dimensional changes due to thermal expansion or wear.

Operating Principles

The indicator operates on a simple mechanical principle: a needle is attached to a spring‑loaded spindle that moves in response to the displacement of the probe tip. As the probe contacts a surface, any movement causes the needle to rotate proportionally, displaying the measurement on the dial. The high resolution and low backlash design ensure that even sub‑millimeter variations are captured accurately.

Calibration and Accuracy

To maintain optimal performance, the MAW42003 should be calibrated periodically against a known standard. The indicator’s internal calibration mechanism allows for quick verification of zero position and scale accuracy. When properly calibrated, it delivers consistent results with an error margin well within industry specifications.

Maintenance Tips

• Keep the probe tip clean and free from debris to avoid measurement drift.
• Avoid excessive force on the probe; gentle contact ensures longevity of the internal spring mechanism.
• Store the instrument in a dry environment to prevent corrosion of moving parts.

Conclusion

The Moore & Wright MAW42003 Dial Indicator combines precision, durability, and user‑friendly design. Its high resolution, generous travel range, and reliable construction make it a trusted tool for engineers, machinists, and quality inspectors who demand accurate linear measurements in every project.
