Page 233: Appendix A: Technical Reference
Appendix A: Technical reference 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 113) for a complete list of parameters. Principles of operation SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries.
Page 234: Echo Processing
Echo Processing A.2.1 Process Intelligence The signal processing technology embedded in Siemens radar level devices is known as Process Intelligence. Process intelligence provides high measurement reliability regardless of the dynamically changing conditions within the vessel being monitored. The embedded Process Intelligence dynamically adjusts to the constantly changing material surfaces within these vessels.
Page 235 Appendix A: Technical reference A.2 Echo Processing ① default TVT ② echo profile ③ material level ④ echo marker 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.

Appendix A: Technical reference A.2 Echo Processing ① default TVT ② material echo selected ③ vessel bottom echo ④ echo marker 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.
Page 238: Echo Lock
Appendix A: Technical reference A.2 Echo Processing A.2.5 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. In radar applications, two measurement verification options are used with Echo Lock (2.8.5.1.): Lock Off SITRANS LR250 responds immediately to a new selected echo (within the restrictions set by...

Page 240: Measurement Range
Appendix A: Technical reference A.2 Echo Processing A.2.7 Measurement Range Near Range (2.8.1.) 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. Near Range allows you to increase the blanking value from its factory default.
Page 241: Damping
Appendix A: Technical reference A.3 Analog Output A.2.9 Damping Damping Filter (2.2.4.) smooths out the response to a sudden change in level. This is an exponential filter and the engineering unit is always in seconds. 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.
Page 242: Sensor Mode
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 Reference point NO SERVICE Measurement and associated loop current not being updated.
Page 243: Loss Of Echo (Loe)
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.

The recommended software package is the SIMATIC Process Device Manager (PDM) by Siemens. SIMATIC PDM This software package is designed to permit easy configuration, monitoring, and troubleshooting of HART devices.

Page 271: Glossary
Glossary accuracy degree of conformity of a measure to a standard or a true value. algorithm a prescribed set of well-defined rules or processes for the solution of a problem in a finite number of steps. ambient temperature the temperature of the surrounding air that comes in contact with the enclosure of the device. antenna an aerial which sends out and receives a signal in a specific direction.
Page 272 Glossary blanking a blind zone extending away from the reference point plus any additional shield length.The device 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.
Page 273 Glossary Echo Confidence describes the quality of an echo. Higher values represent higher quality. Echo Threshold defines the minimum value required for an echo to be accepted as valid and evaluated. Echo Lock Window a window centered on an echo in order to locate and display the echo’s position and true reading.
Page 274 Glossary horn antenna a conical, horn-shaped antenna which focuses microwave signals. The larger the horn diameter, the more focused the radar beam. inductance the property of an electric circuit by virtue of which a varying current induces an electromotive force in that circuit or in a neighboring circuit. 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.
Page 275 Glossary pulse radar a radar type that directly measures distance using short microwave pulses. Distance is determined by the return transit time. 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.
Page 276 Glossary stilling-well see stillpipe. stillpipe a pipe that is mounted inside a vessel parallel to the vessel wall, and is open to the vessel at the bottom. TVT (Time Varying Threshold) a time-varying curve that determines the threshold level above which echoes are determined to be valid.
