The SHT1822-350 high-temperature EMMA tag integrates a SAW micro-acoustic chip fabricated on piezoelectric single crystal, with an aerospace-grade metal housing that works long-term at 350℃ and resists 1200℃ molten steel splash.
Widely used for steel ladles, hot metal ladles, tundish and copper bucket identification - the core sensing hardware of intelligent steelmaking logistics.

Q: Does the tag survive molten steel splash?
A: Yes - aerospace-grade housing resists 1200℃ splash; verified after 1 year at Baosteel.
Q: Does the tag need power or battery replacement?
A: No. The SAW chip is inherently passive with a lifespan over 40 years.
