More Information

Overview Manuals Applications Operating Environment Safety Performance

Features:

  • Uses 78 GHz FMCW radar for narrow-beam, non-contact level measurement.
  • Supports measurement ranges up to 100 m when the selected configuration and application permit.
  • Offers two-wire communication and optional local commissioning interface by order code.
The current product identity covers the LR560 family; its complete Siemens order number defines the mechanical connection, housing, protocol and approval package.

It provides continuous level information for silos, bins and process vessels containing bulk solids or qualifying liquids without contacting the measured material.

Before installation, validate the nozzle position, beam path, process limits, hazardous-area certificate and the control-system protocol assigned to the exact unit.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Monitors powders, granulates and other bulk solids in tall silos where a narrow radar beam helps avoid internal structures.
  • Supports continuous inventory measurement in dusty process vessels without a probe contacting the product surface.
  • Fits process-monitoring duties that require remote level indication through the selected HART or PROFIBUS PA interface.
  • The selected housing and approval must remain within the documented ambient range and enclosure conditions at the mounting point.
  • Process temperature and pressure limits depend on the ordered flange and seal arrangement rather than the family name alone.
  • Dust, buildup and vessel internals should be evaluated so the lens remains clear and the transmitted beam reaches the intended surface.
  • Hazardous-area use requires the exact approved version, matching cable glands and installation practices stated on the nameplate and certificate.
  • Power must be isolated before opening the enclosure where energized conductors or explosive atmospheres could create a risk.
  • Process pressure must be relieved and personnel protected before removing the transmitter from a vessel connection.
  • The 78 GHz operating band produces a narrow beam that improves aiming around vessel obstructions and steep material profiles.
  • Maximum usable range depends on reflectivity, dust, vessel geometry, antenna installation and the ordered process configuration.
  • Commissioning parameters for vessel dimensions and material response determine the reliability of the reported level over the working span.
Description
Siemens SITRANS LR560 is a 2-wire, 78 GHz FMCW radar level transmitter for continuous, non-contact monitoring of solids and long-range liquid applications up to 100 m (328 ft). Its four-degree beam focuses the signal tightly, reducing interference from nozzles and vessel obstructions.

The flush lens antenna provides strong reflection from sloped material surfaces and remains tolerant of product buildup. An integrated air-purge connection supports cleaning in sticky applications, while stainless-steel construction and configurations for high process temperatures suit demanding industrial vessels and silos.

The optional graphical local display uses a Quick Start Wizard and echo-profile view to simplify setup and diagnosis. Typical applications include cement powder, plastic pellets, grain, coal, wood powder, and fly ash, where dependable measurement is required despite dust, uneven surfaces, or difficult vessel geometry.

Technical notes
SITRANS LR560 installation must match the ordered flange, approval, housing, cable entry and loop protocol; do not infer suitability from the LR560 family name alone.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can the exact SITRANS LR560 configuration be identified before purchase?
Record the full Siemens order number and nameplate approvals, then confirm the flange, housing, cable entry, communication protocol and local interface option.
Which control interfaces can be specified for SITRANS LR560?
Applicable versions provide a two-wire 4 to 20 mA/HART interface or PROFIBUS PA; the installed network must match the ordered electronics.
Why is SITRANS LR560 selected for high silos?
Its 78 GHz radar produces a narrow beam and supports long-range non-contact measurement, helping the instrument focus on the material surface in demanding vessel geometry.
How should current SITRANS LR560 supply be checked?
Availability is order-code and approval dependent, so Apter Power verifies the exact configuration, quantity, destination and required date before quoting.
What must be reviewed before replacing an older radar with SITRANS LR560?
Check the process flange, nozzle clearance, range, pressure, temperature, hazardous-area approval, loop protocol and control-system scaling as one engineered change.
What should an SITRANS LR560 documentation inquiry include?
Send the full nameplate, vessel height, measured material, connection size, approval need and protocol so the relevant manual and quotation can be matched.
