PRE1478 HIGH-ACCURACY LENGTH MEASURING SYSTEMS SENSOR SYSTEMS IDEAL FOR MEASURING THE OUTSIDE DIAMETER OF STEEL BALLS AND ROLLERS FOR ANTI-FRICTION BEARINGS
2 • T he wide 10mm measuring range is achieved with a high resolution and accuracy specification that eliminates the inconvenience of the need for frequent resetting to master gages, as required by conventional comparator-type gages, and so fewer of these gages are needed. • Measurement data can be stored and controlled by PC software. • The system can measure high-precision parts such as steel balls and rollers for antifriction bearings by comparison with a master gage, also allowing use as the standard of calibration and evaluation of master gages. Features Quality Assurance LGH Stand 971750 Spindle lifting cable 971753 PC software: SENSORPAK 02NGB070 Standard Accessories: Inspection certificate Option · Calibration certificate · Traceability system chart * To connect between a PC and the exclusive counter, a USB cable (A-B type) is required separately. LGH stand 971750 This LGH stand greatly helps the gage to achieve high accuracy. Mass: 23 kg Maximum measuring range LGH-0510(C )-B-EH : 0 -139 mm LGH-1010(C )-B-EH : 0 -137 mm Measuring table: granite Spindle lifting cable 971753 Mass: 50 g Allows the LGH spindle to be lifted and lowered without touching the measuring head. Custom stand 2* Useful for making a stand incorporating a highaccuracy ceramic platen. (Flatness: 0.3μm) * Custom-made option External signal input connector* Allows external signals to trigger data output and zero-set the counter in combination with the foot switch. * Custom-made option Application example • Data output trigger • Preset (zero-set) • Peak hold clear Custom stand 1* Useful for making a stand to mount a custom jig (to user-specified dimensions). * Custom-made option ø30mm mounting bush* For mounting on a commercially-available stand. (User-specified size acceptable) * Custom-made option PC software: SENSORPAK 02NGB070 This is a software program that allows graphic meter indication and control chart display as well as record / storage of measurement data.
