The SPI 15-979-8 is a horizontal and vertical electronic linear scale designed for precision measurement in machining, fabrication, and metrology applications. Built from stainless steel, it offers a measurement range of 0 to 40 inches, an accuracy of 0.0025 inches, and a resolution of 0.0005 inches. The scale features data output capability, making it suitable for integration with digital readout systems or data logging setups. Two CR2032 lithium batteries are included for immediate use. This instrument is well suited for machinists, toolmakers, and quality control technicians who require reliable, high-resolution linear measurement in shop floor or inspection environments.
The SPI 15-979-8 is used in horizontal and vertical orientations, covering applications such as surface plate inspection, mill table positioning, and linear axis verification on manual or CNC machine tools. Its 40-inch measurement range accommodates a wide variety of workpiece sizes encountered in general machining and fabrication shops. The data output port supports connection to compatible DRO systems or SPC software for process documentation.
Designed for use as a precision linear measurement scale in horizontal and vertical installations on manual machine tools, surface plates, and inspection fixtures where a 0 to 40 inch range and data output are required.
Installation and setup should be performed by a qualified machinist or metrologist familiar with linear scale mounting requirements. Ensure the mounting surface is clean, flat, and free of burrs before securing the scale. Disconnect power from any connected DRO or data acquisition system before wiring the data output connection. Follow the equipment manufacturer guidelines for reader head alignment and cable routing to avoid interference with moving machine components.
