Pressure & Temperature Transmitter

Honeywell's New SmartLine® Pressure & Temperature Transmitters

Honeywell's SmartLine smart measurement system sets the standard for total performance. The pressure transmitters feature industry-leading performance for tighter process control. They also offer the lowest total cost of ownership through a unique modular design, an intuitive human machine interface (HMI) and display, and polarity insensitivity. Smart Connection Suite further supports transmitter messaging and tamper reporting.



SmartLine® Pressure Transmitters

Honeywell’s New SmartLine ST 700 Pressure Transmitter family includes absolute pressure, gauge pressure, flange mount and remote seal transmitters that are superior in performance, stability, reliability and rangeability. With innovative modularity and an intuitive human machine interface (HMI), these products are ideal for a wide range of industrial process applications.

Honeywell’s SmartLine ST 800 Pressure Transmitter family includes absolute pressure, gauge pressure, draft range pressure, flanged and remote seal transmitters. Refineries, chemical and pharmaceutical plants and paper mills around the globe rely on these transmitters for accurate and consistent pressure measurement.

SmartLine® Temperature Transmitters


The STT750 Temperature Transmitters are intended to be a competitive replacement for the STT250 HART field mount temperature transmitters. Suitable for a wide range of control and safety applications, the transmitters provide users with the benefits of the SmartLine platform, including modularity, easier maintenance and lower total cost of ownership.


  • Single universal input
  • Digital accuracy up to 0.14°C for RTD
  • Easy-to-use-and-read basic display
  • Transmitter and sensor diagnostics
  • HART7 communications
  • Full compliance with SIL 2/3 requirements
  • Up to a 3-year warranty
