Installing/mounting 4.1 Basic safety information 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. ● Make sure that the device is suitable for the maximum permissible operating pressure of your system.
Installing/mounting 4.2 Installation location requirements 4.2 Installation location requirements WARNING Aggressive atmospheres Danger to personnel, system and environment can result from unsuitable environment. ● Provide an environment suitable to the housing rating and materials of construction. NOTICE Direct sunlight Device damage. The device can overheat or materials become brittle due to UV exposure. ● Protect the device from direct sunlight.

Appendix A: Technical reference A Note Where a number follows the parameter name [for example, Master Reset (4.1.)] this is the parameter access number via the handheld programmer. See Parameter Reference (Page 107) for a complete list of parameters. A.1 Principles of operation SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries. (The microwave output level is significantly less than that emitted from cellular phones.
Appendix A: Technical reference A.2 Echo Processing Process Intelligence is able to differentiate between the true microwave reflections from the surface of the material and unwanted reflections being returned from obstructions such as seam welds or supports within a vessel. The result is repeatable, fast and reliable measurement. This technology was developed as result of field data gained over some twenty years from more than 1,000,000 installations in many industries around the world.
Appendix A: Technical reference A.2 Echo Processing The device characterizes all echoes that rise above the TVT as potential good echoes. Each peak is assigned a rating based on its strength, area, height above the TVT, and reliability, amongst other characteristics. Algorithm (2.8.4.1.) The true echo is selected based on the setting for the Echo selection algorithm. Options are true First Echo, Largest Echo, or best of First and Largest. Position Detect (2.8.4.2.

Appendix A: Technical reference A.2 Echo Processing A.2.3 CLEF Range CLEF Range (2.8.4.4.) is referenced from Low Calibration Point (process empty level ). When the Hybrid algorithm is selected in Position Detect (2.8.4.2.), the CLEF algorithm will be applied up to the limit of CLEF Range. Above this limit the Center algorithm will be applied. 4 3 2 1 ① ② ③ ④ ⑤ A.2.

Near Range programs SITRANS LR250 to ignore the zone in front of the antenna. The default blanking distance is 50 mm (1.97") from the end of the antenna.
Appendix A: Technical reference A.3 Analog Output Once the real process fill/empty rate (m/s by default) is established, a response rate can be selected that is slightly higher than the application rate. Response Rate automatically adjusts the filters that affect the output response rate. Response Rate (2.4.1.) * A.2.9 Fill Rate per Minute (2.4.2.)/Empty Rate per Mi‐ nute (2.4.3.) Slow Damping Filter (2.2.4.) 0.1 m/min (0.32 ft/min) 10 s Medium 1.0 m/min (3.28 ft.min) 10 s Fast 10.0 m/min (32.
Appendix A: Technical reference A.3 Analog Output A.3.1 Sensor Mode This parameter controls the input. Depending on the reference point used, the measurement reports either Level, Space, or Distance. By default Sensor Mode is set to Level. Operation Description NO SERVICE 1) Reference point Measurement and associated loop current not being updated. Device defaults to Fail-safe mode 1).
Appendix A: Technical reference A.3 Analog Output A.3.3 Loss of Echo (LOE) A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable because the echo confidence value has dropped below the echo confidence threshold. Confidence (2.8.6.1.) describes the quality of an echo. Higher values represent higher quality. Echo Threshold (2.8.4.3.) defines the minimum confidence value required for an echo to be accepted as valid and evaluated.
Appendix A: Technical reference A.4 Maximum Process Temperature Chart A.4 Maximum Process Temperature Chart WARNING Exceeded maximum internal and process temperatures Danger of device malfunction ● Internal temperature must not exceed +80 ° C (+176 °F). ● Process temperature must not exceed limits specified by the antenna type. Note ● The chart below is for guidance only. ● The chart does not represent every possible process connection arrangement.
Appendix A: Technical reference A.5 Process Pressure/Temperature derating curves A.5 Process Pressure/Temperature derating curves WARNING Exceeded maximum permissible operating pressure Danger of injury or poisoning.
