Temperature Probe os4200
Information >>>


The os4200 Temperature Probe 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 os4200’s body is a sealed, stainless steel tube that protects the FBG. Since there are no epoxies holding the fiber to the tube, long term stability is ensured by design.
