Encoder is compatible with MRI/NMR applications
A
Micronor product story
Edited by the Engineeringtalk editorial team
Jul 24, 2009
Micronor's MR318 fibre-optic rotary encoder is designed specifically for use as feedback in motion control systems operating in extreme electromagnetic fields.
The sensor's passive optical design and non-metallic construction has no effect on MRI (magnetic resonance imaging) or NMR (nuclear magnetic resonance) system operation or measurements.
The multi-turn encoder system offers 360ppr (1-deg) resolution and measures both angular position and shaft speed.
MRI-related applications include feedback for actuator or motor control, monitoring patient position or correlating foot-pedal position for fMRI diagnostics.
The MR318 uses an industry-standard size 58mm encoder housing so that it mounts and installs just like a conventional encoder.
The sensor then optically connects to the MR310 module via a multimode optical fibre link.
The module operates from 15-32VDC and offers a range of standard interface options, including: A/B quadrature outputs (push-pull and line driver), programmable analogue outputs (4-20mA and +/-10V) and RS422/RS485 serial interface.
