Coating life time (excluding effects of chemical incompatibility)
The FluoMini optical temperature sensor measures temperature by applying a fluorescent temperature coating on an object and measurings contact-free or via a probe. The coating is “read” by aiming the probe towards the coating. The maximum distance to the coating should be 5-10 cm.
An advantage of this system is that the coating does not suffer from photobleaching and can last years (excluding chemical incompatibility). Also, the sensor can be applied in various applications, where contact with the object is avoided or objects in motion.
