Why SITRANS LT500?

SITRANS LT500 is the next evolution of level and pump controllers for radar and ultrasonic transmitters, transducers, or any 2-wire 4-20 mA device. With applications ranging from basic level measurement to complex pumping routines, it optimizes operations and delivers significant cost savings through intelligent level and pump control. The SITRANS LT500 controller offers:

  • Measurement types: Level, distance, space, volume, differential, average, head and Open Channel Flow
  • Measuring range: Sensor-based with SITRANS LR110/LR120 and SITRANS Probe LU240, and ultrasonic transducers
  • Communications: Up to three 4 to 20 mA outputs
  • Fieldbus option cards: EtherNet IP, HART, Modbus RTU, Modbus TCP, PROFIBUS DP, PROFIBUS PA, or PROFINET options
  • Outputs: 2 x 4 ... 20 mA, + 1 x 4-20 mA output with HART card, 6 x relay and fieldbus

Simple setup and configuration

Quickly commission using intuitive Quick Start Wizards, multiple display views and flexible configuration tools. Six fully programmable relays streamline pump control, alarming and overall setup, saving time and effort.

Achieve accurate and versatile measurement

Ensure precise measurement for liquids or solids using SITRANS LR110/120 radar, Probe LU240 and ultrasonic transducers, or mA inputs to meet a wide range of application needs.

Optimize processes with data and connectivity

Improve process performance with datalogging, parameter backup and easy configuration transfers. Access immediate status and diagnostics through digital-ready Ethernet/IP, HART, Modbus, PROFIBUS or PROFINET for smarter operations.

Featured capabilities

Proven experience

40+ years of controller experience backed by more than 170 years of Siemens’ innovative engineering experience and millions of installed process instruments in the field.

Environmental compliance

Controlling your application keeps you operating within local legislation. From basic level control to complex pumping routines, protect the environment while keeping accurate records of your process.

Reduced carbon footprint

Schedule pumps before high-demand periods and save money. Connectivity and reliable level measurement reduce CO2 emissions. Programmable features – grease ring reduction, pump runtime and alternating pumps – reduce maintenance.

Safety first

Reduce personnel access to vessel tops or confined spaces. High-level alarms and backup level override help prevent overflow of hazardous materials. Put safety first with simple push-button configuration from the controller.

Process optimization

Digitalization ready for connection to the cloud, IIoT or networks using standard industry protocols and onboard datalogging for events, totalizers, pumps and more. Everything at your fingertips or just a touch away.
