Siemens LT500 Level Controller for Radar Level Transmitters
SiemensThe Siemens SITRANS LT500 is an advanced level monitor and controller designed for use with radar level transmitters, providing comprehensive level monitoring, pump control, alarm management, and open channel flow measurement for one or two process measurement points. Compatible with Siemens radar transmitters such as the SITRANS LR110 and SITRANS LR120, the LT500 delivers reliable control for water, wastewater, and industrial storage applications.
Supporting single- and dual-point level measurement, the LT500 combines advanced control functionality with flexible communications and configurable I/O to simplify process automation. It is ideal for wet wells, chemical storage tanks, flumes, weirs, hoppers, crusher bins, liquid storage, and other applications where accurate continuous level measurement and dependable control are required.
The controller features an intuitive local HMI with four-button programming, guided setup wizards, and menu-driven configuration for quick commissioning. Automatic false echo suppression improves measurement reliability by ignoring reflections from fixed obstructions, while removable terminal blocks simplify installation and servicing.
The LT500 receives continuous level measurements from one or two compatible radar level transmitters using 4-20 mA or HART communication. It processes this information to calculate level, volume, differential level, or open channel flow and uses configurable relays and outputs to automate pumps, trigger alarms, and communicate process data to PLCs, SCADA systems, and other control platforms.
