Fowler 54-580-250-0 Electronic Indicator Base Kit

Product Description

The FOWLER 54-580-250-0 is a two-piece electronic indicator base kit designed for precision measurement work in machine shops, manufacturing, and inspection environments. The kit pairs a magnetic base with a plain bearing electronic indicator, delivering accuracy to plus or minus 0.001 inches across a measurement range of 0.001 to 1.0000 inches. The magnetic base provides a stable, repositionable mounting point on ferrous machine surfaces, while the articulating arm and post give the technician the reach and positioning flexibility needed for setup and inspection tasks. Machinists, toolmakers, and quality control personnel are the primary users of this kit.

This kit suits surface plate inspection, lathe and mill setup, runout checks, and part alignment verification in both job shop and production environments. The electronic indicator with a 0 to 100 dial reading and a 2.25-inch black dial face makes readings straightforward under shop lighting. The 8.0-inch arm and 8.0-inch post height allow the indicator to reach most standard workpiece geometries without additional extensions. The base footprint of 8.0 inches by 8.0 inches provides a stable foundation on flat ferrous surfaces.

Key Features

• Electronic indicator type with plain bearing for smooth, consistent plunger travel
• Accuracy of plus or minus 0.001 inches over a 0.001 to 1.0000 inch measurement range
• Magnetic base style for secure, repositionable mounting on ferrous machine surfaces
• 2.25-inch black dial face with 0.001 inch graduation and 0-100 dial reading for clear readability
• 8.0-inch arm length and 8.0-inch post height for extended reach and positioning flexibility
• Two-piece kit includes both the magnetic base and electronic indicator

Compatibility

Designed as a self-contained two-piece electronic indicator base kit suitable for general-purpose precision measurement and inspection on ferrous machine surfaces in standard shop applications.

Installation Notes

Setup is performed by machinists or quality control technicians and requires no special certifications. Before mounting, ensure the target surface is clean and free of chips or coolant that could reduce magnetic holding force. Power down any rotating spindles or moving axes before positioning the indicator against a workpiece. Do not exceed the indicator travel range, as forcing the plunger beyond its rated maximum measurement can damage the internal bearing and sensing mechanism.
