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.

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.

Note 1: FBGs from 200pm to 3.0nm BW@3dB (FWHM) are supported. Best performance results obtained using 300pm FBGs.

Note 2: The enhanced NANOSENSE software available for the SX family of interrogators is the result of years of experience with field installations of Optical Sensing Systems and contains an easy to use sensors configurator, auto and/or manual threshold settings for each FBG, sensors referencing, post-processing of data with rolling functions over the collected data, notifications and alerts based on user set threshold values, replicating of existing sensors functions, and auto-recovery after accidental power outages. Includes provision for 3rd party developers via API support. The NanoSense software is provided free of charge with each S1 interrogator.
