Micronor AG

Fiber Optic Absolute Encoder

100% Passive Fiber Optic Absolute Position Sensor System to control position in presence of strong electromagnetic fields.

Micronor MR330 series is the only 100% Passive Fiber Optic Absolute Position Sensor System available on the market today. The innovative design is based on an all-optical passive sensor and remote interrogator module interconnected by an industry-standard multimode fiber optic link. Features include:
• Passive sensor requires no remote power supply, isolation barriers or EX cabinets
• Immune to any electro-magnetic interference such as lightning, radiation and magnetic fields
• Temperature range -40°C to +80°C
• Sensors are Ex classified “simple mechanical device” and can be installed in all manner of hazardous locations and explosive environments – mines, gas and dust
• Controller provides “inherently safe, optical radiation” and can be installed in non-hazardous location up to 300 meters away
• ATEX approved for EPL Mb/Gb/Gc/Db/Dc applications
• Provides interference-free position feedback over long distances
• Outperforms resolvers and electronics-based encoders in harsh and hazardous environments
  • Fibre-optic apparatus
