| The Spherosyn Technology Advantage Environmental Protection All variants of Newall encoders carry an Ingress Protection (IP) rating of 67 (NEMA 6). The encoders are fully submersible and will continue to provide accurate and dependable readings under the harshest conditiions. Unite most gbss based systems, no air purging is required. Dirt,swarf, cast iron dust, graphite dust and other common contaminates will not effect the Shock and Vibration In comparison to other linear displacement technologies,SHG and MHG are • Shock and Impact (11ms IEC 69-2-6): Spherosyn technology = I000m/s2 (I00g) • Vibration (55 - 2000Hz IEC 68-2-27): Spherosyn technology = 300m/s2 (30g Slew Rate Newall encoders will not skip count even at high traverse rates. In its TTL output form,a slew rate of up to 20 metres/second can be achieved,while the Absolute version carries a slew rate of up to 60 metres/second. Newall encoders require no regular cleaning or maintenance. Unlike noncontact systems, the encoders have no general wear characteristics. There are no LEDs to burn out or glass to get scratched or broken. There are no Ease of Installation metres machined su rfaces or bad^ng bars are nut needed. Fop more The laser measurament system used to calibrate all of Newall scales have been calibrated by accredited laboratories providing traceability to UK ntandard Specification BS578I/Iriternational Standard ISOI00I2-I . The National Physical Laboratory (NPL) calibrates the master standard, certificate number 08A0I4/950I. All Newall Calibration rigs are traceable back to this NPL standard.
