Non-metallic Temperature Sensor os4300
Information >>>


The os4300 Non-metallic Temperature Sensor is a family of gages designed to make fiber handling easy and sensor installation fast and repeatable. It is based on fiber Bragg grating (FBG) technology. The os4300’s body is a sealed, alumina ceramic tube that protects the FBG. 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 response.
