Siemens SITRANS LT500 universal level controller

$800.00

The Siemens SITRANS LT500 universal level controller is a versatile and advanced level and pump control unit for industrial applications. It can connect with radar, ultrasonic or any 4‑20 mA level devices to provide reliable continuous level monitoring, controller logic and advanced alarm/pump management.

Because the LT500 supports multiple communication protocols and advanced diagnostics, it enhances process transparency and reduces maintenance needs in level, volume, flow and pump control systems.

Typical applications include wet wells, tanks, open channels and pump stations.

Not Recommended For:
• Simple local level indication only
• Basic systems without control or alarm requirements

Selection Notes

• Confirm the sensor type you will connect, such as radar, ultrasonic or generic 4‑20 mA transmitters.
• Determine whether single point or dual point monitoring is required.
• Choose the required communication protocols, such as HART, Modbus, PROFIBUS or PROFINET.
• Verify the necessary relay count for alarms and pump control.
• In addition, confirm mounting style (wall, panel or remote panel) and required power supply type.

Why Choose the Siemens SITRANS LT500

Universal Compatibility
The LT500 controller connects with radar transducers, ultrasonic sensors, or any 4‑20 mA level device, making it ideal for many liquid, solids or mixed media applications.

Flexible Level Applications
It supports single and dual point level monitoring, volume calculations and differential control. As a result, the controller can be used in simple or complex process systems.

Advanced Pump and Alarm Control
Up to 6 programmable relays can manage pump operation, alarms or interlocks, offering logic control for automation tasks.

Multiple Communications and Diagnostics
LT500 supports HART, Modbus RTU, Modbus TCP, PROFIBUS DP/PA, PROFINET and EtherNet/IP. Therefore, it integrates easily with SCADA and automation systems.

User‑Friendly Interface
The controller features an easy‑to‑use HMI with menu navigation and wizard‑based setup. In addition, local display options help operators monitor level and pump status at a glance.

Data Logging and Process Insights
The LT500 includes on‑board data logging and parameter backup. Consequently, operators can analyze historical level and event data for process optimization.
