  • Page 11: The Manual

    The application example used in this manual illustrates a typical installation using SITRANS LR 460. There is often more than one way to approach an application, and other configurations may also apply. If the example does not apply to your application, check the applicable parameter reference for the available options.

    The high frequency signal creates a narrow emission cone, which makes the LR 460 quite insensitive to vessel interferences. SITRANS LR 460 is available with an optional air purge connection for cleaning the interior of the antenna. Programming SITRANS LR 460 carries out its level measurement function according to the set of built-in parameter tables.

    Easy Aimer loosen the Easy Aimer ball locking bolts and gently reposition the enclosure. Direct SITRANS LR 460 so the horn antenna is pointed at an angle perpendicular to the material surface, if possible. (As a guide, aim the beam at a point approximately 2/3 of the way across the tank diameter.)

  • Page 24: Air Purging System

    • Some dust particles are highly abrasive and can be drawn into the inside of the horn during purge cleaning, damaging the internal PTFE emitter of the antenna. A replacement kit is available from your local Siemens Milltronics representative. • It is the customer’s responsibility to ensure that any vacuum or pressure in the measured vessel is maintained, considering the hole that passes through the process connection and SITRANS LR 460 antenna system.

    Appendix A: Technical Reference Principles of Operation SITRANS LR 460 is a long range FMCW (Frequency Modulated Continuous Wave) radar transmitter. Radar level measurement uses the time of flight principle to determine distance to a material surface. FMCW radar transmits a continuous wave. The frequency of the wave is constantly increasing: this is known as the sweep.

    Each peak gets a rating based on its strength, area, height above the TVT, and other Echo Algorithm parameters. The true echo is selected based on the setting for on page 53. Page A-70 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01...

  • Page 79: False Echoes

    The TVT adjustment parameters allow you to manipulate the TVT (Time Varying Threshold), so that SITRANS LR 460 will ignore false echoes. The default TVT hovers above the echo profile, and effectively screens out small false echoes.
