  • Page 89: Appendix B: Technical Reference

    Appendix B: 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. The transmit time is directly proportional to the distance to the material.

  • Page 90: Echo Lock

    Values Material Agitator Total Lock • When Echo Lock is Off, SITRANS LR 460 responds immediately to a new measurement (within the restrictions set by the Maximum Fill / Empty Rate). However, measurement reliability is affected. • When Maximum Verification or Material Agitator is selected, a new measurement outside the Echo Lock Window must meet the sampling criteria.

  • Page 91: Loe Timer

    Auto False-Echo Suppression The TVT adjustment parameters allow you to set a TVT (Time Varying Threshold) curve, so that SITRANS LR 460 will ignore false echoes. The default TVT curve hovers above the echo profile, and effectively screens out small false echoes.
  • Page 92 See page 69 for examples of the echo profile before and after using Auto False-Echo Suppression.

If you try to set a SITRANS LR 460 parameter via remote communications, but the parameter remains unchanged, make sure remote operation is enabled. See Remote operation enable on page 26. Also make sure that Write Locking is Off. See Write locking on page 27.

    Appendix D: Maintenance SITRANS LR 460 requires no maintenance or cleaning under normal operating conditions. Under severe operating conditions, the antenna may require periodic cleaning. If cleaning becomes necessary: • Note the antenna material and the process medium, and select a cleaning solution that will not react adversely with either.
