FSI S1PC Static and Dynamic Interrogators

Datasheet

Description

The S1PC optical sensing instrument is a self-contained economic commercial grade interrogator, featuring 1 monitoring channel and an internal industrial PC. This fanless Class 1 Laser instrument is enclosed in a field deployable enclosure, and can be operated in full spectrum and in sensor peak detection modes. The S1PC is available in both static (1Hz scan rate) or dynamic (800Hz scan rate) models, and provides measurements, over its 80nm scanning range per channel, of up to 30 Fiber Bragg Gratings (FBG) based sensors on its 1 channel.

The rugged technology platform on which our SX interrogators pare based is used extensively in civil engineering, geotechnical, roads, mines, energy, industrial, medical, and many other commercial applications. This economy model is specifically useful for monitoring temperatures and the slow changes of strains, tilt or inclination, pressure, and other engineering parameters. The platform is also suitable for process control, material qualification labs, and R&D programs. The industrial grade design scales well for volume production.

Benefits

Resolution, accuracy and dynamic range: The S1PC Interrogator provides measurements across its wavelength scanning range of 80nm. The instrument features 1pm resolution and +/- 12pm accuracy over the entire operating temperature of the instrument, and 30dB dynamic range with automatic control
adjustments. Manual settings option for thresholds and gain stages also included.

Excellent reliability: The S1PC Interrogator is based on a solid-state IEC 60825-1 Class 1 laser platform that has been deployed in large volume in various field applications worldwide. The interrogator has no tunable filters. Excellent reliability over the standard operating temperature range of -5C to +50C.
The S1PC is suitable for use as an integral part of a very rugged and reliable sensing system.

Adaptive to more types of sensors: The integrated electronics, depolarized light source, static and dynamic configurations, and embedded software allow the user to quickly adapt the instrument’s performance parameters to fit many different sensor configurations. Designed to monitor many types of sensors from narrow bandwidth (200pm) FBGs used in temperature, strain, displacement, tilt and pressure sensors, to wide bandwidth (3.0nm) FBGs used in bio-sensing. Hardware implementation of peak tracking algorithms for FBG sensors included.

Low Cost and High Quality: The S1PC Interrogator addresses applications demanding the lowest cost while maintaining the reliability of a high quality instrument.
