Monitoring temperatures over long distances
The measurement technology is based on fiber Bragg gratings (FBGs). FBGs are created by exposing the fiber to a periodic pattern of intense UV radiation at a specific position. Several FBGs (typically 15 to 20) can be written into a single fiber and read out simultaneously with one system. This technology allows temperature monitoring over long distances of up to several kilometers. The measurement range covers cryogenic temperatures and extends to approx. +600 degrees Celsius with an achievable resolution of up to 0.1°C and a maximum spatial resolution of about one centimeter. Polytec offers fiber sensors depending on the interrogator (readout system) used and the application according to your individual requirements.
Whether your application requires static or dynamic real-time recording or periodic monitoring, Polytec offers the right system for your task. The robust, turnkey interrogators deliver fast and highly accurate measurements from hundreds of fiber Bragg gratings or extrinsic Fabry-Perot sensors.
si155
The si155 is a fanless optical interrogator for industrial applications. It offers both static and dynamic full-spectrum analysis and delivers long-term, reliable and accurate measurements from hundreds of sensors on 4 parallel channels.
The system has an extremely low-noise high-power wave laser and guarantees absolute accuracy with every scan. The HYPERION platform on which the si155 is based offers groundbreaking functions, including high-performance on-board DSP and real-time FPGA processing. This enables fast full-spectrum data acquisition and flexible peak detection algorithms from fiber Bragg gratings (FBG), long-term FBGs and Fabry-Perot (FP) sensors with low latency for data access to closed-loop feedback applications.

Fiber Bragg Grating Sensor os1100
The os1100 Fiber Bragg Grating (FBG) is designed for use in fiber optic sensing applications. It is a single FBG centered in a two meter length of polyimide coated optical fiber. It may be used individually or can be spliced into an array of many FBGs.
Fiber Bragg Grating Sensor os1200
The os1200 FBG array (Fiber Bragg Grating) is designed for use in fiber optic sensor applications. It is a six-meter-long PI fiber with five centered FBGs, which are arranged at intervals of one meter.
Temperature compensation sensor os4100
The os4100 is a temperature compensation sensor. It is spot welded, glued or screwed with epoxy resin and was specially developed for the os3100 strain gage. The stainless steel support of the os4100 keeps the FBG under tension and protects the fiber during installation. Because no epoxies hold the fiber on the carrier, long-term stability is guaranteed.
Temperatur Probe os4200
os4200 temperature probes are sealed stainless steel tubes that facilitate handling and enable quick, repeatable sensor installation. Since no epoxies hold the fiber to the tube, long-term stability is guaranteed. Just as sensitive and just like thermocouples, the os4200 offers response times of less than a second, a larger operating range, no calibration and no EMI noise. The sensor is suitable for use in harsh environments and can be used alone or in series at the end of a sensor array.
Non-metallic Temperatur Sensor os4300
The temperature sensor os4300 is available in three versions and is housed in a sealed aluminum oxide ceramic tube, which makes handling easier and enables fast, repeatable sensor installation. Since no epoxies hold the fiber to the tube, long-term stability is guaranteed. Just as sensitive and just like thermocouples, the os4300 offers response times of less than a second, a larger operating range, no calibration and no EMI noise. The sensor is suitable for use in harsh environments. Three housing options enable installation that is comparable to thermocouples with reinforced cables and protected connections. The sensor can be used alone or in series as a sensor array.
