OS4300 : Non-Metallic Temperature Sensors
OS4310 , OS4330 , OS4350
The os4300 Non-Metallic Temperature Sensors are housed within a sealed, alumina ceramic tube designed to make 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 os4300 is equally sensitive and accurate, while providing sub-second response time, wider operating range, no calibration, and no EMI noise. The os4300 temperature sensor is qualified for use in harsh environments and delivers the many advantages inherent to all FBG based sensors.
Three packaging options provide for installation that mimics that of conventional thermocouples with armored cables and protected connectors, and small sensors that provide the user with both installation flexibility and sub-second thermal response.
This sensor can be used alone or in series as part of an FBG sensor array. 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.
