Fiber Optic Absolute Position Sensor, MR330

Type:  Sensor
Description:  The MR330 series Fiber Optic Absolute Position Sensor System features an all-optical design that combines interference-free sensing, long distance transmission, absolute angular measurement from 0° to 360° with 13-bit resolution and 12-bit multiturn tracking. A complete measurement system consists of the MR332 Passive Sensor and MR330 Controller which are optically linked with standard Duplex LC multimode fiber connections. The MR332 passive sensor design is EMI immune, withstands lightning strikes and is ATEX approved for use in hazardous locations. Model MR330-1 SSI Controller operates from 24 VDC and features multiple built-in interfaces for maximum system compatibility.
Connectivity:  Modbus RTU
Features:  100% passive optical sensor; Immune to electromagnetic interference (EMI); No electromagnetic emissions; No ground loops; ATEX Classified: Inherently safe simple apparatus; Optical Link can extend up 2500 meters; Non-metallic version to be available for MRI applications; Controller provides multiple built-in interfaces for maximum system compatibility
