Features

Rosemount™ 3051S Thermal Range Expander
  • Seal system with two different fill fluids extends the operating temperature range up to 770 °F (410 °C)
  • Optimized for use in various high process temperature applications and low ambient temperature conditions
  • Eliminates the need for heat tracing and impulse piping which reduces installation costs
  • Operates with process temperatures as low as -157 °F (-105 °C) and high as 770 °F (410°C) for application adaptability
  • Advanced diagnostics provide diagnostic coverage to detect electrical loop issues and abnormal process conditions
  • Tuned-Systems can reduce temperature effects by 10-20% and improve response time by 80% vs. traditional installations
  • Allows for direct mounting, remote mounting and balanced systems to meet various application requirements
  • SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
Rosemount™ 319 Flushing Rings
  • Less labor, faster installations
    • Pre-assembled - no need for multiple vendor piece parts.
    • Factory leak tested for reliable in-field performance.
    • Fast maintenance for substantial process uptime.
  • Drastically Reduces Maintenance time
    • A simple way for maintenance staff to safely vent or drain excess pressure in the line.
    • A convenient method to access process fluid for sampling.
    • Can calibrate against a known pressure without disassembling the instrument connection.
  • Works with nearly any process type
