Communication interfaces include 422, 232, 485, 4-20mA, etc.
1. Specially designed for high-temperature test objects such as molten steel, molten aluminum, and steel ladles, effectively filtering multi-band light interference from molten iron, ensuring stable accuracy and long-term measurement stability even when measuring high-temperature objects.
2. Extremely low reflectivity design allows for effective detection of low-reflectivity objects such as slag and reddish-brown porous materials, significantly improving the success rate of measurements on various object types.
3. Unique high-temperature operating environment design, employing high-temperature resistant lasers, photosensitive components, and temperature control devices, achieving low temperature drift and long service life, ensuring long-term stable operation in environments exceeding 80 degrees Celsius.
4. A perfect replacement for imported products, achieving domestic substitution.
Can measure molten steel and aluminum in reddish-brown or bright silver states, and can operate stably in high-temperature environments up to 85℃.
Billet heating furnace, slab heating furnace, hot-rolled strip coiling, hot-rolled strip post-processing line, aluminum water tank level monitoring, etc.
