STT850 — Honeywell STT850 Smart Temperature Transmitter
The Honeywell STT850 Smart Temperature Transmitter delivers accurate temperature measurement for Saudi Arabia's harshest process environments. Supporting all standard thermocouple and RTD sensor types, the STT850 features Honeywell's patented dual-sensor technology for sensor backup and drift detection. Its HART 7 and FOUNDATION Fieldbus communication capabilities ensure compatibility with Aramco DCS infrastructure and SABIC safety systems. The STT850 meets SIL 2 requirements per IEC 61508 for process safety applications in Saudi petrochemical facilities. Its stainless steel housing with IP68 protection rating withstands the extreme heat and humidity of Saudi Arabian coastal industrial sites. The transmitter's remote configuration capability supports SADARA and Ma'aden plant maintenance programs with reduced field intervention requirements.
