The Siemens SITRANS LR500 is an 80 GHz radar level transmitter series for industrial applications that need high accuracy and advanced diagnostics. It measures liquids, slurries and solids in storage and process vessels. The series has 4 models (LR510, LR530, LR550, LR580) that differ by antenna type and application. Siemens verified accuracy is 1 mm.

Why SITRANS LR500

- Accurate, non-contact measurement: a narrow beam and high signal sensitivity measure reliably despite dust, vapor, turbulence or complex vessel shapes.

- Process Intelligence: adapts in real time with dynamic threshold curves and echo discrimination, ignoring noise from turbulence, agitators and vessel structures.

- Near Range Suppression: detects and removes false echoes from material buildup near the antenna, which reduces false high-level readings, nuisance alarms and cleaning.

- Volume calculation: converts distance to level or volume using built-in tank and silo geometries or custom strapping tables.

- Flexible setup: use the local interface, a mobile device wirelessly, or the control system.

- Diagnostics and verification: health monitoring and verification tools help detect issues early and support maintenance and quality assurance.

- Built for safety and compliance: low energy consumption, hazardous-area approvals, and wide pressure and temperature capability.

Models in the series

- SITRANS LR510: threaded lens antenna for liquids

- SITRANS LR530: flanged encapsulated antenna for extreme conditions

- SITRANS LR550: polymeric horn antenna for solids and liquids, long range, 3° narrow beam

- SITRANS LR580: lens antenna with integrated aiming flange for solids

Typical applications

- Anaerobic digesters, to prevent overfills and reduce maintenance

- Raw-material tanks and silos for dusty solids

- Tanks with agitators or turbulent liquids

- Storage and process vessels in industrial plants

Frequently asked questions about the SITRANS LR500

1. How much does the SITRANS LR500 cost?

Price depends on the model and connection size. Send the material, tank height, temperature and pressure of your application via LINE @gotcorp to request a quotation from the GOT team.

2. How do I choose between the LR510, LR530, LR550 and LR580?

For general liquids, choose the LR510. For extreme conditions (-196 to 200°C, up to 25 bar), choose the LR530. For solids or liquids that need long range and a narrow beam, choose the LR550. For solids that need an aiming flange and an air purge connection, choose the LR580.

3. Can it measure in a tank with an agitator or turbulent liquid?

Yes. Process Intelligence is designed to ignore noise from turbulence, agitators and vessel structures. Send the tank drawing and mounting position to a GOT engineer to check before you order.

4. Will material buildup near the sensor cause wrong readings?

Near Range Suppression removes false echoes from buildup near the antenna, reducing false high-level readings and nuisance alarms. For very heavy buildup, ask a GOT engineer to assess your site.

5. Can it measure volume or silo inventory?

Yes. It converts the measured distance to level or volume using built-in tank and silo geometries or a custom strapping table.

6. How accurate is it?

Siemens has verified 1 mm accuracy. Actual results depend on the installation and the material measured.

7. Can it be used in hazardous areas?

Hazardous-area approvals are available. Before ordering, specify the zone and standard your plant requires so we can match the model to the approval documents.

8. How is the LR500 different from the LR100?

The LR100 is a compact model focused on easy installation and low power. The LR500 is for process applications needing 1 mm accuracy, advanced diagnostics, Process Intelligence, and a wider pressure and temperature range.

9. What is the warranty, and is it in stock?

[Confirm with GOT: warranty period, stock in Thailand, delivery time.] Contact the team via LINE @gotcorp to check stock and delivery.
