SITRANS LUT400 Series

The Siemens SITRANS LUT400 series controllers are compact, single point, long-range ultrasonic controllers for continuous level, or volume measurement of liquids, slurries, and solids, and high accuracy monitoring of open channel flow.

  • The SITRANS LUT400 comes in three different models, depending on the application, level of performance and functionality required:
  • SITRANS LUT420 Level Controller: Level or volume measurement of liquids, slurries, and solids, as well as basic pump control functions, and basic data logging capability
  • SITRANS LUT430 Level, Volume, Pump and Flow Controller: Includes all features of the LUT420 plus a full suite of advanced pump control and alarm functionality, open channel flow monitoring, and basic flow data logging capability
  • SITRANS LUT440 High Accuracy OCM: Our most featured, highest accuracy model. Includes all features of the LUT430, plus the industry’s best accuracy (± 1 mm within 3 m), full suite of advanced control functionality, and enhanced flow logging capability

Features:

  • Small 1/2 DIN enclosure [144 h x 144 d x 146 w mm (5.7 x 5.7 x 5.75 inch)] with standard universal mounting bracket for wall, pipe, and DIN rail, plus an optional panel mount
  • Easy to use LUI display with local four-button programming, menu-driven parameters, and Wizard support for key applications
  • Level, Volume, OCM Flow monitoring
  • Three relays combined with a suite of pump, alarm, and relay control features
  • HART Communications
  • EDDs for SIMATIC PDM, AMS Device Manager, and Field Communicator 375/475, plus DTMs for FDTs (Field Device Tools)
  • Web browser for local programming from an intuitive web-based interface
  • Two discrete inputs for backup level override and pump interlock functions
  • Echo profile and trend views from the local display
  • Patented digital receiver for improved performance in electrically noisy applications (close proximity to VSDs)
  • Real time clock with daylight savings time, supporting an integrated datalogger and energy saving algorithms for minimizing pump operation during high cost energy periods
  • Removable terminal blocks for ease of wiring
