Installing/mounting 4.1 4 Basic safety notes DANGER Pressure applications Danger to personnel, system and environment will result from improper disassembly. ● Never attempt to loosen, remove, or disassemble process connection while vessel contents are under pressure. Note Material compatibility Siemens can provide you with support concerning selection of sensor components wetted by process media. However, you are responsible for the selection of components.
Installing/mounting 4.1 Basic safety notes 4.1.1 External stresses and loads CAUTION External stresses and loads Damage to device by severe external stresses and loads (e.g. thermal expansion or pipe tension). Process media can be released. ● Prevent severe external stresses and loads from acting on the device. 4.1.2 Installation location requirements NOTICE Aggressive atmospheres Damage to device through penetration of aggressive vapors. ● Ensure that the device is suitable for the application.
Installing/mounting 4.2 Disassembly 4.1.3 Proper mounting NOTICE Incorrect mounting The device can be damaged, destroyed, or its functionality impaired through improper mounting. ● Before installing ensure there is no visible damage to the device. ● Make sure that process connectors are clean, and suitable gaskets and glands are used. ● Mount the device using suitable tools. Refer to the information in Technical data (Page 125). Note ● Correct location is key to a successful application.
Installing/mounting 4.3 Proper mounting 4.3 Proper mounting 4.3.1 Nozzle location note Note Beam angle depends on horn size. For details on avoiding false echoes, see Auto False Echo Suppression (Page 55). 4.3.2 Nozzle location ① ② Minimum 1 m (39") Beam angle 2" horn = 15° 3" horn = 10° 4" horn = 8° ● Keep emission cone free of interference from ladders, pipes, I-beams or filling streams. ● Avoid central locations on tall, narrow vessels.

Appendix A: Technical reference A.3 Echo Processing A.3.3 Echo Lock If the echo selected by Algorithm is within the Echo Lock window, the window is centered about the echo, which is used to derive the measurement. ● Lock Off: SITRANS LR260 responds immediately to a new selected echo (within the restrictions set by the Maximum Fill / Empty Rate), but measurement reliability is affected. A.3.4 Echo Position Detection The echo position algorithm (2.2.4.1.2.
Appendix A: Technical reference A.3 Echo Processing Auto False Echo Suppression Range must be set to a distance shorter than the distance to the material level when the environment was learned, to avoid the material echo being screened out.

Appendix A: Technical reference A.5 Measurement Response A.4 Measurement Range A.4.1 Near Range Near Range programs (2.2.1.12) (Page 81) SITRANS LR260 to ignore the zone in front of the antenna. The default blanking distance is 50 mm (1.97 inch) from end of horn antenna. Near Range allows you to increase the blanking value from its factory default. Auto False Echo Suppression (2.2.5.2) (Page 87) is generally recommended in preference to extending the blanking distance from factory values. A.4.
Appendix A: Technical reference A.7 Damping A.6 mA 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).
Appendix A: Technical reference A.8 Loss of Echo (LOE) Damping example ① ② ③ ④ Level (m) Time (s) Input (level) Smoothed output ● time constant = 2 seconds ● input (level) change = 2 m ● In 5 time constants the output rises exponentially: from 63.2% of the change in the first time constant, to almost 100% of the change by the end of the 5th time constant.

Appendix A: Technical reference A.9 Fail-safe Mode A.9 Fail-safe Mode A.9.1 Fail-safe Mode The purpose of the Fail-safe setting is to put the process into a safe mode of operation in the event of a fault or failure. The value to be reported in the event of a fault is selected so that a loss of power or loss of signal triggers the same response as an unsafe level. A.9.2 Fail-safe Timer Fail-safe Timer determines the time to elapse after the last valid reading before a Failsafe state is activated.
Appendix A: Technical reference A.10 Process Pressure/Temperature derating curves A.10 Process Pressure/Temperature derating curves WARNING Exceeded maximum permissible operating pressure Danger of injury or poisoning. The maximum permissible operating pressure depends on the device version. The device can be damaged if the operating pressure is exceeded. Hot, toxic and corrosive process media could be released.
Appendix A: Technical reference A.12 Loop power Siemens Level Transmitters with flanged, threaded, or sanitary clamp type process mounts have no pressure-bearing housing of their own and, therefore, do not come under the Pressure Equipment Directive as pressure or safety accessories (see EU Commission Guideline A-08 and A-20).

There are four basic types of antenna in radar level measurement, horn, parabolic, rod, and waveguide.
Glossary blanking a blind zone extending away from the reference point plus any additional shield length.The instrument is programmed to ignore this zone. capacitance the property of a system of conductors and dielectrics that permits the storage of electricity when potential differences exist between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference, and the unit is a Farad. confidence Higher values represent higher quality.

The unit is a Henry. microwaves the term for the electromagnetic frequencies occupying the portion of the radio frequency spectrum from 1 GHz to 300 GHz. multiple echoes secondary echoes that appear as double, triple, or quadruple echoes in the distance from the target echo.
Glossary radar radar is an acronym for RAdio Detection And Ranging. A device that radiates electromagnetic waves and utilizes the reflection of such waves from distant objects to determine their existence or position. range distance between a transmitter and a target. range extension the distance below the zero percent or empty point in a vessel.
