SM800 850nm FBG Sensor Chains
FBG Sensor Chains for use with FiSpec Interrogators
The SM800 FBG Sensor Chain is a spliceless chain of multiple high-precision FBG sensors “written” into the core of a single SM800 single mode fiber length. When the sensor is paired with a FiSens® interrogator offers a multipoint, distributed sensing solution for temperature or strain measurements. The FBG sensor chains utilize a unique fentosecond (fs-Laser) Laser Inscription method offering an innovative FBG-based solution with best performance together with lowest cost per sensor point on the market.
Specifications
The following is a summary specification of FiSens FBG Sensor Chains. Consult the individual data sheets and manual for detailed performance and interface information.
| Measurement Range | Max Temperature Range= -250°C to +800°C, but actual range depends on selected combination of Fiber, Jacketing and Capillary options chosen for sensor chain. Widest temperature range is usually restricted to the capillary section as the FO Connector and Lead-In are typically lesser rated. If each temperature point moves in the same direction, then max temperature measurement range is possible.Max Strain Range= ±40,000με for 1-FBG sensor chain. For multiple FBGs, strain range is a function of Fiber option, # of FBGs, spectral spacing, and direction of strain (positive or negative). If each strain point moves in the same direction, then max strain range is possible.
IMPORTANT NOTE: Actual measurement range – temperature and/or strain – depends on selected Fiber, Jacketing, Capillary and FBG-spacing as well as direction of measurement parameter (positive or negative). Contact Micronor Sensors sales for guidance if >300°C or >2000 με is required. |

Ordering Information
Every FBG sensor application and sensor configuration is different. Micronor specializes in providing the unique configuration that your application requires. Typical lead time is 10-12 Weeks ARO for small quantities of customer sensors. An Ordering Part Number can be assigned and quoted within 1-2 business days.
We offer STOCK FBG sensors to get you started and becoming familiar with FBG technology and operation of the FBGX interrogators. For example, a popular 1-FBG bare fiber sensor is FBG-MR0150, A=P-1-W-PK-FI, B=2000-200-100. Consult the Quick Ship table for this and other configurations usually available in stock.
