SITRANS LUT430 / LUT440
Siemens
Ultrasonic Level Controller
The Siemens SITRANS LUT400 series controllers are compact, single-point, long-range ultrasonic controllers for a continuous level or volume measurement of liquids, slurries and solids, and high-accuracy monitoring of open channel flow.
The SITRANS LUT400 ultrasonic level controller comes in three different models, depending on the application, level of performance and functionality: SITRANS LUT420 Level Controller, SITRANS LUT430 Level, SITRANS LUT440 High Accuracy OCM.
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 interlock functions
- Echo profile and trend views from the local display
