SI-4HR-SS digital road surface temperature infrared temperature sensor/SDI-12/rectangular viewing angle
Digital SDI-12 output, rectangular (rectangular) viewing angle observation probe, horizontal half angle 16 ° and vertical field of view 5 °
Product details
The SI-4HR-SS infrared temperature sensor uses an optical germanium lens and is based on the principle of non-contact infrared temperature measurement. It can continuously measure the surface temperature of objects under field conditions.
SI-4HR-SS is specially developed for road weather observation networks, equipped with a unique rectangular (rectangular) viewing angle observation probe, with a horizontal half angle of 16 ° and a vertical field of view of 5 °, which can eliminate the influence of surrounding environments such as the sky and accurately detect narrow target roads at long distances.
The sensor adopts digital SDI-12 output and is equipped with M8 standard interface, making it easy to replace cables and connect Apogee AT-100 recorder.
