How are labels or engravings on the sensor surface kept clear at 300°C?
For sensors operating at 300°C, conventional adhesive labels or inks would degrade rapidly. To maintain clear identification, specialized high-temperature resistant marking technologies are employed. These often include laser engraving directly onto the metal encapsulation or using high-temperature resistant ceramic inks that are fired onto the surface, ensuring the markings remain legible throughout the sensor’s operational lifespan.
For applications requiring high-temperature sensing, such as at 300°C, we recommend the OFSCN® 300°C Fiber Bragg Grating Temperature Sensor. This sensor utilizes seamless steel tube encapsulation, which is designed to withstand extreme environments, implicitly requiring its identification marks to be equally robust.
