Tamagawa Angle Calibration

Tamagawa Angle Calibration Tamagawa Seiki was the first private company in Japan that was certified and registered as an accredited angle calibration laboratory since Japan’s angle standard was established in 2003. Based on this accreditation, we newly started angle calibration business, which is carried out in accordance with the international accreditation standard: ISO17025 granted to laboratories or calibration organizations performing angle inspection precisely. We were certified and registered as an accredited angle calibration laboratory for JCSS (Japan Calibration Service System) in 2008. Accredited angle calibration laboratories calibrate the angle of the object instruments on the basis of the specified procedures and issue certificates to assure the traceability to the national standard. The certificate is also effective in the world. FEATURES Possible to perform ultra-precise angle calibration up to the resolution of 0.001 arc-second Possible to measure at 36,000 points per revolution Possible to calibrate large-size instruments (Weight: 50 kg/φ400mm/Shaft torque: 0.3 Nm) Applicable to calibration for performance evaluations of glass code discs and couplings as well Tamagawa Seiki was recognized by the calibration organization by JCSS. Authorization criteria is ISO/IEC 17025.JCSS is managed by IAJapan who is a signatory to the international Laboratory Accreditation Cooperation(ILAC) and Asia Pacific Laboratory Accreditation Cooperation(APLAC).Technical- Quality-Management section is recognized by the calibration organization by JCSS.It is internationally effective to the Mutual Recognition Arrangement(MRA). JCSS0227 is the authorization number of this Technical-Quality-Management section. About Angle Calibration Business We accept your calibration request for angle sensors Please contact us when you need to measure the accuracy of your angle sensor correctly. We calibrate the angle sensor and issue a certificate with JCSS accreditation symbol. Applications of an angle sensor with a calibration certificate (1) Use it as a reference sensor of angle calibrator. (2) Install it in an angle calibrator and calibrate the equipment. (3) Perform the accuracy compensation based on calibrated values after incorporating it into your system. ROM accuracy compensation can enhance the accuracy up to a reproducibility level of an angle sensor. We sell calibration certificate-attached angle sensors, which are traceable to the national standard We can attach calibration certificates to our angle sensors. We provide rotary encoders and resolvers with high precision specifications. Responsive to global Mutual Recognition Agreement (MRA) Our calibration services and the sales of certificate-attached angle sensors are acceptable in the world. Outline of calibration work and calibration certificates Calibration work is carried out rotating the axis slowly through the attachment tool. In order to consider the misalignment of attachment and the influence of coupling, measurement is performed two or more times in six attachment places. The calibration certificate includes a table and a graph representation which show the average deflection at six attachment places data as the deflection of the angle sensor. Moreover, the uncertainty of measurement is numerically expressed, and the ambiguity contained in a calibration result is defined numerically.
