To cater for various different applications i.e temperature range, temperature resolution etc. a wide range of different sensor types are available.
Generally the sensors consist of an electronic unit with an integrated measuring system as well as a special metallic gold plated parabolic reflector. This mirror unit ensures that the measurement signal will be gathered by multiple reflection and the signal-noise ratio will be considerably enhanced. By doing so, the measurement accuracy on a highly reflective surface of ±5 °C is achieved at a measurement temperature of 40 °C.
Accurate temperature measurement is maintained even with a variation of the distance from the substrate..
Also Angles of up to ±5° are allowed without significantly reducing the measurement accuracy.
The distance between the sensor and the surface depends on the type of sensor that is chosen. Distances from 80 mm up to 110 mm from the surface can be used without sacrificing measurement accuracy.
The sensor can be customized by the addition of readily available serial interface Sensor (Interface protocol RS485) therefore meeting the required measurement task. Many parameters like emissivity, response time, analog outputs or alarm configurations can be changed online.
