    Fiber Optic Sensors are for operating environments where electronics-based sensors are hazardous or unreliable. These applications typically require immunity to emi/rfi, magnetic fields, electric fields, plasma fields, RF environments, microwave ovens, high voltage, radiation, and extended distances.

    Micronor specializes in fiber optic kinetic sensors for feedback in mechanical motion applications where immunity to interference, voltage, RF, microwaves, magnetic fields, and/or radiation is required:

    • POSITION, absolute rotary and linear sensors
    • MOTION, incremental rotary and linear sensors
    • SIGNALING & SECURITY, E-Stop, microswitch, key switch, pushbutton and manhole sensor
    • ACCELERATION, Multiaxis acceleration sensors for real-time vibration analysis
    • TEMPERATURE, Fiber optic thermometers for industry, medical, research and OEM
    • TEMPERATURE AND STRAIN, Fiber Bragg Grating interrogators and multipoint sensor chains for medical, industrial, structural, and OEM applications

    By definition, a fiber optic sensor consists of the passive Sensor, active Signal Condition/Controller and the fiber optic link that connects them. The Controller is active, sourcing light to the Sensor and interrogating the return light signal according to its underlying optical principle. The Controller provides standard electrical interfaces that make the fiber optic aspect of the system transparent to the user’s control system. Hence, a FO absolute encoder outputs position via SSI or analog output, an incremental encoder outputs A/B quadrature signals or analog output for monitoring speed or relative position, an emergency stop provides relay contacts for control, and a temperature sensor system outputs digital values via USB in °F or °C units. Sensors are available based on either SM/MM Glass (GOF) or Polymer (POF) optical fiber link technology.

    Some applications and the fiber optic sensor attributes which enable them:

    • MEDICAL. Non-metallic MRI safe sensors enable fMRI functionality and medical device development. Applications include MRI cradle position, MRI phantoms, and MRI-guide biopsy and surgical robots.
    • PHARMA & FOOD PROCESSING. FO temperature sensors are non-metallic and can operate inside microwave ovens and microwave reactors.
    • ENERGY. Utility and energy applications require immunity to high voltage and all dialectric design. Fiber optic encoders can monitor tap changer position, switchgear state, generator and top drive speed. FO temperature sensors can measure hot spots in transformers, bus bars and switchgear. FO acceleration sensors can monitor transformer end winding stress and internal vibration.
    • SEMICONDUCTOR. FO temperature and strain sensors can operation in high voltage plasma, microwave, RF and  high magnetic fields.
    • INDUSTRIAL. Industrial applications benefit from fiber’s interference feedback and inherent safety. A few examples include welding robots, smelters, mines, chemical plants and food processing.
    • TRANSPORTATION. Electric railways, aerial trams, and aerospace benefit from the passive sensors’s electrical isolation and immunity to high  voltage and lightning.
    • MINING. Fiber optic position sensors provide inherent safety as well as can traverse the distances needed to monitor and control underground boring equipment and long conveyor systems.
    • CIVIL. Multipoint FBG strain sensors can monitor strain, movement, and shifting in buildings, bridges, tunnels, composites, and other structures in advance of potential failure
    • INFRASTRUCTURE. Fiber optic position sensors traverse the distances needed to monitor and control lift bridges, dams, floodgates, sluice gates, and hydroelectric plants.  


  • Low cost FiSpec FBG Interrogator for Temp & Strain
    Ultraminiature, precise and robust 1-channel & 4-channel FiSpec FBG Interrogators provides a cost-disruptive solution enabling the integration of FBG multipoint temperature/strain sensing into OEM designs that could not previously justify the technology....

  • With an unprecedented small size, the 1-channel FBGX100 and 4-channel FiSpec FBGX400 integrates all necessary components for the analysis of up to 120 fiber Bragg grating (FBG) sensors, max 30 FBGs per channel. Each channel operates independently and allows sampling rate up to 100 Hz regardless of the number of FBGs and channels connected.  Its compact and energy-efficient design enables FBG based applications where space and power is limited. 

    Depending on the Capillary option selected, Temperature designated FBGs have a measurement range of -40°C to +600°, with 0.1°C precision and 0.001°C resolution.  For strain monitoring, the measure range is ± 6300 με, with 1 με precision and 0.01 με resolution.

    The FBGX series interrogators operates in the 850nm window compatible with SM800-based FBG sensor chains. It is a fully integrated FBG Interrogator with embedded light source, spectrometer, and on-board processing.  The product incorporates a dual function Micro USB which provides both 5VDC power and supports communications.  A serial UART port is also available with connection for both serial communications and 5V DC power input.

    Multipoint SM800 FBG sensor chains are available optimized for the user’s application.  The customer’s configuration defines: (1) temperature or strain measurement, (2) number of FBGs, (3) type and length of lead-in, (4) narrow or wide spectral range (FBGX100 requires Wide option),  (5) FBG spacing, (6) capillary option and length(bare fiber, silica, PEEK or SS) , (7) lead-out length, and (8) special wavelength assignments (when required).  Each FBG is about 1mm wide and can be spaced as close as 2mm apart. FBG sensors chains (each with unique wavelength assignment) can be daisy chained (via connector or splice) for special applications.
