Fibre optic system receives US patent
A
Micronor product story
Edited by the Engineeringtalk editorial team
Aug 10, 2007
The wavelength division multiplexing approach used in Micronor's ZapFREE produces a totally passive encoder using no electronics within the sensor.
Micronor has secured US patent 7,196,320 for its ZapFREE fibre optic rotary encoder system.
The patent recognises Micronor's innovative wavelength division multiplexing approach which produces a totally passive encoder using no electronics within the sensor - and therefore deployable in stressful environments not suited for conventional electronic-based encoders.
The Micronor encoders meet ATEX requirements as "a simple apparatus" and are certified for use in hazardous environments.
An MRI-transparent encoder has been recently developed for the medical industry.
The technology was commercially introduced in 2004 as the MR3XX series ZapFREE fibre optic encoder series.
Customer applications now range from aerial cable cars to electric trains; from mines to steel mills to oil rigs.
The MR3XX sensors mechanically mount like any conventional rotary encoder - then connect by a simplex fibre optic link to a MR310 remote encoder interface (REI) module.
The versatile REI module offers an array of standard interfaces that ensures connectivity with all major motor drive, motion control and PLC systems.
