    Fiber-optic measurement technology

Fiber-optic measurement technology & sensors: imc fos4Test

The new fos4Test opto-electrical measurement amplifiers from imc enable precise measurements with fiber Bragg-based sensors.

FBG sensors enable measurements in environments where electrical sensors reach their limits. Unlike electrical measurement methods, this purely optical method is completely insensitive to environmental influences.

Equipped with 4 channels, the measurement amplifiers in the Expert-version, with up to 25 kHz sampling rate per channel, capture the signals of the FGB sensors - without aliasing.

Easy integration and comfortable operation

An Ethernet interface enables quick and easy connection of the systems to a PC or to the company network.

With comprehensive integration into the imc STUDIO measurement software , users of the fos4X systems have access to a market-proven tool for measuring, controlling and automating.

Synchronous measurements with all imc measurement system families

In addition to the fos4Test series, all other imc measurement systems can be operated synchronously during one measurement. This allows the combination of classic electrical sensors together with FBG sensors and offers a variety of application possibilities. This means that almost all current sensors can be used to record physical quantities, such as pressures, forces, speeds, vibrations, sounds, temperatures, voltages or currents.

Advantages of the fos4Test fiber-optic measurement amplifier

  • High-precision measurements even in tough environmental conditions

  • High sampling rates up to 25 kHz (fos4Test expert)
  • Multiple sensors per fiber possible (fos4Test nSense)
  • Synchronous measurement with all imc measurement system families via imc STUDIO
  • High-precision synchronization using precision time protocol (IEEE-1588)
  • Connection of additional electrical sensors

What are FBG sensors?

FBG sensors consist of a glass fiber into which one or more fiber Bragg gratings are inserted. These fiber Bragg gratings are formed when the refractive index of the glass fiber is cyclically changed during manufacture under the influence of a laser. When the glass fiber is illuminated, a characteristic wavelength is now reflected and this wavelength changes under strain.

Advantage of the fos4x series fiber optic sensors:

  • No influence from electrical voltages or magnetic fields
  • Can be used in explosive and high-explosive environments
  • Low installation costs and short set-up times
  • Strain measurements with 10 times higher bending radii and 1,000 times more load changes compared to classic strain gauge sensors
  • Long supply lines at up to several hundred meters without loss of quality
  • Long lifetime
  • Corrosion and moisture resistant
