The sensors are based on an inductive sensing method with an accuracy of up to 10 arc-seconds. Their claimed benefits include:
• the ability to calibrate the encoder in situ, for the highest possible accuracy;
• a low-profile shape with a large bore, making the sensors compact, light weight and easy to install;
• a rugged construction that resists dust, dirt, oil, water and other contaminants;
• the ability to generate calibration tables and store calibration data in on-board electronics by communicating via a bespoke serial interface;
• a choice of sizes (37–300mm) and mounting formats;
• a duplex mechanical format that provides electrical redundancy, for enhanced safety; and
• immunity to external magnetic fields.
“Our new Field Calibration IncOder provides the best of both worlds: the superior accuracy of optical encoders, with the robustness of our inductive IncOder series,” says Swapnil Mane, Celera’s vice-president of product management and marketing. “And it achieves this in a low-profile, inductive sensor package. By enabling customers to store calibration data within IncOder after installation, a gearshift in accuracy performance is made possible.”
The sensors are configurable in terms of mounting format, connections, supply voltage, single- or multi-turn outputs, and support for digital protocols including BiSS-C, SSI, SPI, ABZ and asynchronous serial outputs.
The new angle sensors combine optical encoder accuracy with inductive robustness, allowing precision measurements in challenging environments
