  • Page 86: Technical Reference

    Technical reference Principles of operation SITRANS Probe LR is a sophisticated radar instrument that uses advanced microwave pulse technology to provide non-contacting continuous level measurement in liquids or slurries. Radar level measurement uses the time of flight principle to determine distance to a material surface.

    Technical reference A.3 Near blanking Typical receiver signal ① End of transmit ② P800 Near blanking ③ Distance from process empty level to reference point P006 ④ Empty level ⑤ Range extension (P801) as % P006 Near blanking Near Blanking programs SITRANS Probe LR to ignore the zone in front of the antenna.

  • Page 88: Range Extension

    Technical reference A.5 Range extension Range extension In applications where the base of the vessel is conical or parabolic, a reliable echo may be available below the vessel empty distance, due to an indirect reflection path. Increasing the range extension to 30% or 40% can provide stable empty vessel readings. Range extension is entered as a percentage of P006 (process empty level).

  • Page 90: Output

    Technical reference A.9 Output Output The mA output is proportional to the level, in the range 4 to 20 mA. Generally, the output is set so that the output for 0% is 4 mA, and the output for 100% is 20 mA. 0 and 100% are percentages of the full-scale reading (m, cm, mm, ft, in).

    Technical reference A.10 Failsafe A.10 Failsafe The Failsafe function can be activated either if there is not a valid measurement, or by one of the faults marked by an asterisk in the table General Fault Codes on page 84. In Failsafe mode, the device will output one of the four options determined by P071 (Failsafe Material Level).
