The os4200 series includes three options for stainless steel temperature probes based on fiber Bragg grating (FBG) technology.
The os4200 Temperature Probes are sealed, stainless steel tubes that are designed to make handling and installation easy, fast and repeatable. With no epoxies holding the fiber to the tube, long term stability is ensured by design.
In side by side comparisons with conventional thermocouples, the os4200 is equally sensitive and accurate, while providing sub-second response time, wider operating range, no calibration, and no EMI noise. The os4200 Temperature Probe is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.
This sensor can be used alone or in series at the end of an FBG sensor array. Installation and cabling for such arrays is much less expensive and cumbersome than comparable electronic gage networks. Options include packages that operate like conventional thermocouples with armored cables, protected connectors and small probes that provide the user with both installation flexibility and sub-second response time.
With each sensor, Luna provides a Sensor Information Sheet listing the calibration coefficients needed to convert wavelength information into temperature. The ENLIGHT Sensing Software provides a utility to calculate and then record, display, and transmit data for large networks of sensors
