Product Name: Extra Length baseline Measuring Device with Granite Guideways Model NO.: EX-50 Customized: Customized Certification: JIS, DIN, GB, SGS Precision Measuring Device: Precision Measuring Device Accuracy: A Measure Method: Automatic Precision: 0.01mm Resolution: 0.01mm Range: 0~80m Measurement Object: Length Material: Granite Type: baseline Device Measuring Range: 80m Straightness of The Guideways: <0.5mm Uncertainty: U=(0.2+1.15L)Um K=2 Machine base: High Precision Natural Granite Application: Laser Calibration Trademark: Qianshao Transport Package: Wooden Case Specification: SGS Origin: Qingdao China HS Code: 9031900090 Product Description Extra Length baseline Device with GraniteGuidewaysDevice Instruction:1.This device is a high accuracy guideways system made by some high accuracy coalescing guideways and patent technology(patent No:ZL200420039252.7)air bearing slide platforms.2. The length measuring system adopted XD1L150S double frequency laser interfere system made by API company.Technical data:1.The displacement of the slide platforms reach 80 meters max.2.The straightness of the guideways is less than 0.5MM within 50 meters.3.The uncertain degree is U=(0.2+1.15L)um k=24. We could be able to manufacture the device reach more than 100m.Characteristic:1.The first complete granite construction exceeding long guideways in the world.2.High accuracy and hih stability.3.The slide platforms realized no friction and quiet moving.Application:1. Mainly used to calibrate various large engineering measuring instrument such as laser tracing instrument, laser distance measuring instrument.2. To provide the tracing to the source of the measured value tor large engineering projects such as industry construction, automobile, watercraft and railwawy vehicles manufactures.3.Currently theChina National Institute of Metrology equiped with the 80m device, The Shanghai Academy of Public Measurement and Guangzhou Institute of Metrology equiped with the50m devide.
