struktura i prednosti od termometar

struktura i prednosti of infracrven termometar. The infracrven pirometar focuses the infracrven zrake primljeno od the mjeren objekt on the detektor kroz the leće kroz the filter, i the detektor generati a struja or voltage signal proporcionalno to temperatura kroz the integration of the radiation gustoća of the measured objekt, which is then connected to In the electric components, this temperature signal is linearized, corrected for the emissivity area, and pretvoreno u A Standard izlaz signal.

1. Aimer
The collimator has this effect, and the measure block or measure point by the pyrometer can be seen, the collimator can often be used for large-area measured objects. For small objects and long measured distances, sights with instrument panel scales or laser pointing points in the form of light-transmitting leće are recommended.

2. Objektiv
The lens determines the measured point of the pirometar. For large-area objects, a pyrometer with a fixed focal length is općenito sibleible. But when the measurement distance is far from the focus point, the image at the edge of the measurement point will be unclear. For this reason, it is better to use a a zoom lens. Within the given zoom range, the pyrometer can adjust the measurement distance. The latest pyrometer has a zoomable zamjenjiv objektiv. The near lens and the far lens can be replaced without rekalibracija.

3. Senzori, i.e. spektralni prijemnici
Temperature is obrnuto proporcionalno to valna duljina. At low object temperatures, sensors sensitive to long-wave spectral regions (hot-film senzori or pyroelectric senzori) are prikladni, at high temperatures, Short-Wave Sensitive Sensors Composed of Germanium, Silicon, indij-galij, etc. will be used Photoelectric Sensors.
