As part of the SmartLine® product family, the STT850 is an advanced temperature transmitter that delivers reliable accuracy and stability over a wide range of process and ambient temperatures. The SmartLine series is fully tested and compatible with Experion® PKS, ensuring smooth integration and high system compatibility.

Designed for constant performance under varying environmental conditions, the STT850 combines accurate measurements, fast response time, comprehensive diagnostic functions and digital communication in a modular and maintenance-friendly design. Thanks to its high installed accuracy, the STT850 can easily replace an existing transmitter in many cases.

Like all SmartLine transmitters, the STT850 features digitally accessible diagnostic tools that provide early warnings of potential failures. This increases operational reliability, helps prevent unplanned downtime and contributes to lower operating costs.
