Mitutoyo 518-223 High Precision Absolute Digital Height Gauge, 0-600mm Range, 0.005mm Resolution, +/-0.00011+.0002xL/ 40″ Accuracy, 27kg Mass
The Mitutoyo 518-223 high precision Absolute digital height gauge has a measurement range of 0” to 24” (0 to 600 mm), a backlit, LCD digital readout with selectable resolution to 0.00005” (0.001 mm), and data output to transmit results to a Mitutoyo miniprocessor or computer for statistical process control (SPC). The gauge is accurate to + or – 0.00011+.0002xL/40” where L is the range travelled from the base position.
This height gauge has an electronic microprocessor providing the ability to preset a reference height at any position, to set a temporary zero position and return to a true zero reading, to compensate for the diameter of the probe tip, and to set upper and lower tolerance bounds. The LCD’s dual-color (green and red) backlighting (GO/±NG) indicates in- or out-of-tolerance measurements when bounds are set. The gauge also supports inside or outside diameter measurement of an object by tracing from the circle apex. The LCD digital readout is selectable for display of measurements in inches or metric units. The output port transmits results to a Mitutoyo miniprocessor or computer through an interface cable (not included) for SPC, or through an alternate RS-232C port. An electrostatic capacitance linear encoder helps prevent overspeed errors to ensure repeatable, precise measurement. The 5-mm diameter stepped electronic touch-signal probe supports precise digital measurement with triggering in both up and down direction. A slider elevation knob supports hand-operated travel on the roller-bearing beam, with a large feed wheel for even adjustment. The height gauge weighs 59.53 lbs (27 kg).
Height gauges, also called gages, are precision measuring instruments that travel on a vertical column (also called the beam) to measure and/or mark the vertical distance from the base of an object in fine units. The vertical position of the gauge and its attached pointer are changed by turning a calibrated screw, or one or more feed wheels. Recorded rotations are read from a scale, a dial, counters, and/or an electronic display. A screw clamp holds an electronic touch-signal probe to the gauge. On compatible units, the probe may be replaced by a pointer that is typically sharpened to act as a scriber, and can be used to mark position on a workpiece by scratching its surface. Height gauges are typically used in manufacturing, machining, and mechanical engineering.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
