STT850


STT850

Certified to the Experion® PKS standard, the product supports seamless integration with Honeywell DCS systems and is suitable for petrochemical, power, mechanical manufacturing, refrigeration systems and other applications to meet the demanding temperature monitoring needs.

Introduction

Part of the SmartLine® family of products, the SmartLine STT850 is a high-performance temperature transmitter offering high accuracy and stability over a wide range of  process and ambient temperatures. The SmartLine family is also fully tested and compliant with Experion ® PKS providing the highest level of compatibility assurance and integration capabilities. SmartLine easily meets the most demanding needs for temperature measurement applications.


Core performance advantage

1. High precision and stability
      RTD digital accuracy: up to ±0.10℃, to ensure the precise capture of small temperature changes.

      Long-term stability: The annual drift rate is only 0.01% of the URL, supporting up to 10 years of stable operation, some models provide 15 years of ultra-long warranty.

      Fast response: single input model update time 125ms, dual input model 250ms, suitable for dynamic temperature monitoring scenarios.
2. Reliability and security
      Built-in isolation and redundancy design: double chamber structure, electrical isolation function, support temperature difference/average/redundancy/segment measurement, reduce the risk of signal interference.
      Intelligent diagnosis and safety certification: Integrated sensor break detection, self-diagnosis function, in line with SIL 2/3 safety level and Namur 107/89 standard, to ensure the safety of equipment and systems.

3. Modular flexible configuration
     Extensible display and configuration: Support basic LCD or advanced graphic LCD watch head, multi-language interface (including Chinese), display unit can be switched (℃/℉/K, etc.), modular design allows on-site display module or replacement of electronic parts.
     Multi-protocol compatibility: Support 4-20mA, HART® 7.0, Honeywell DE Protocol and FOUNDATION™ Fieldbus for mainstream industrial communication systems.
