SITRANS LR260 Overview SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of solids and liquids in storage vessels including extreme levels of dust and high temperatures, to a range of 30 m (98.4 ft). The instrument consists of an electronic component coupled to a horn antenna with an integral Easy Aimer and flange or threaded connection for quick and easy positioning. A dust cover or air purging are available as options.

Installation WARNINGS: • Installation shall only be performed by qualified personnel and in accordance with local governing regulations. • SITRANS LR260 is to be used only in the manner outlined in this manual, otherwise protection provided by the device may be impaired. • Never attempt to loosen, remove, or disassemble process connection or instrument housing while vessel contents are under pressure.
Mounting location Notes: • Correct location is key to a successful application. • Avoid reflective interference from vessel walls and obstructions by following the guidelines below. Nozzle design • The end of the horn must protrude a minimum of 10 mm (0.4”) to avoid false echoes being reflected from the nozzle. • Optional antenna extensions: 100 mm (3.93"), 200 mm (70.9"), 500 mm (19.69"), 1000 mm (39.4")1) Nozzle location Min. clearance: 10 mm (0.4") min.
Nozzle location (continued) • • • Provide easy access for viewing the display and programming via the hand programmer. Provide an environment suitable to the housing rating and materials of construction. Provide a sunshield if the instrument will be mounted in direct sunlight.

Air Purging System (Optional) For more frequent cleaning, a purging system can be installed between the flange and the horn antenna. The system provides an 1/8" inlet (female thread) on the flange where cooling air or cleaning fluid passes through the flange and exits the inside of the horn to clean it. The customer will supply the purging medium by a manual or automatic valve system. This option is only available with the universal flange for purging shown on page 18.

Dust Cap (Optional) Note: The dust cap must be removed before using the Air Purge feature (see Air Purging System (Optional) on page 17). The dust cap fits onto the end of the horn and prevents the buildup of dust and other process material inside the horn. • It is particularly useful for applications in areas of high humidity, or with bulk solids with a high moisture content. Three sizes are available, to fit the standard 2", 3" and 4" horns. • Installation 1. Thoroughly clean inside the horn.
Wiring Power WARNINGS: The DC input terminals shall be supplied from a source providing electrical isolation between the input and output, in order to meet the applicable safety requirements of IEC 61010-1. All field wiring must have insulation suitable for rated voltages. Connecting SITRANS LR260 WARNINGS: • Check the nameplate on your instrument, to verify the approval rating. • Use appropriate conduit seals to maintain IP or NEMA rating.

Notes: • The mA Output Function is set independently from the setting in Operation. Set Operation first and then mA Output Function. (Operation resets mA Output Function to the same value.) • The mA Output Function controls the primary value and the loop current for the SITRANS LR260. Use caution when changing the mA Output function when connected to a HART network. • mA Output Function must be set to Manual before you can modify the mA Output Value (2.3.1.1).
2.3.1.4. 20 mA Setpoint Sets the process level corresponding to the 20 mA value. 20 mA always defaults to 100%, and mA Output Function determines whether this is a Level, Space, or Distance measurement. Level and Space are measured as a percentage of the difference between High Calibration Point and Low Calibration Point: Distance is measured as a percentage of Low Calibration Point.
2.3.1.8. 20 mA Output Trim Calibrates the 20 mA output. The mA output of the device is pre-calibrated; however, 20 mA Output Trim can be used to trim remote displays or inputs.

Appendix C: Maintenance SITRANS LR260 requires no maintenance or cleaning under normal operating conditions. Under severe operating conditions, the horn 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. • Remove the instrument from service and wipe the antenna clean using a cloth and suitable cleaning solution.
Appendix D: Technical Reference Principles of Operation SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of solids and liquids1). Radar level measurement uses the time of flight principle to determine distance to a material surface. The device transmits a signal and waits for the return echo. The transit time is directly proportional to the distance from the material. Pulse radar uses polarized electromagnetic waves.
Higher order mathematical techniques and algorithms are used to provide intelligent processing of microwave reflection profiles. This “knowledge based” technique produces superior performance and reliability. Time Varying Threshold (TVT) Curves A Time Varying Threshold (TVT) curve hovers above the echo profile to screen out unwanted reflections (false echoes). sensor reference point High Cal. Pt. =0 obstruction at 1.2 m TVT curve material level at 2.9 m false echo true echo Low Cal. Pt.
The options are Center, CLEF (Constrained Leading Edge Fit), Hybrid or Rising Edge. CLEF uses the leading edge of the echo. It can be used to compensate for materials with a low dK value, which may cause the vessel bottom to be reported as the level instead of the actual material level, in low level conditions. CLEF range is the level below which the CLEF algorithm will be used: above this level the Center algorithm is used.
Far Range 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.1) Measurement Response The measurement response (response rate) limits the maximum rate at which the display and output respond to changes in the measurement.
When the instrument is returned to Measurement mode, the transceiver resumes operation. The reading and mA output default to the last measurement taken. The reading and associated outputs migrate to the current process level at a rate controlled by the response rate (2.2.7.1). If SITRANS LR260 is left in PROGRAM mode for 10 minutes without input, it automatically reverts to Measurement mode. Damping A damping filter smooths out the response to a sudden change in level.
Fail-safe Timer Fail-safe Timer determines the time to elapse after the last valid reading before a Failsafe state is activated. Fail-safe Material Level determines the level to be reported when the Fail-safe timer expires. Upon receiving a reliable echo, the loss of echo condition is aborted, the Service Required icon and error message are cleared, and the reading and mA output return to the current level. Fail-safe Material Level When the 2.4.1.
