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.

Benefits

• 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 inter- lock 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 inte- grated datalogger and energy saving algorithms for minimizing pump operation during high cost energy periods
• Removable terminal blocks for ease of wiring

Applications

The SITRANS LUT400 comes in three different models, depend-
ing on the application, level of performance and functionality re-
quired:

• SITRANS LUT420 Level Controller: Level or volume measure- ment 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

Key applications: wet wells, reservoirs, flumes/weirs, chemical storage, liquid storage, hoppers, crusher bins, dry solids storage
