© Siemens AG 2016 Level Measurement Continuous level measurement - Ultrasonic transmitters SITRANS Probe LU ■ Overview ■ Configuration Parabolic mounting 4 SITRANS Probe LU is a 2-wire loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in open channels, storage vessels, and simple process vessels. Flat mounting and beam angle ■ Benefits Fill • Continuous level measurement up to 12 m (40 ft) range • Easy installation and simple startup • Programming using infrared Intrinsically Safe handheld programmer, SIMATIC PDM or HART Communicator • Communication using HART or PROFIBUS PA • ETFE or PVDF transducers for chemical compatibility • Sonic Intelligence signal processing • Auto False-Echo Suppression for fixed obstruction avoidance • Level to volume or level to flow conversion Pipe Rungs ■ Application The SITRANS Probe LU is ideal for level monitoring in the water and wastewater industry, chemical storage vessels, and small bulk hoppers. The range of SITRANS Probe LU is 6 or 12 m (20 or 40 ft). Using Sonic Intelligence, Auto False Echo Suppression for fixed obstruction avoidance, and accuracy of 0.15 % of range or 6 mm (0.25 inch), the Probe LU provides unmatched reliability. The Probe LU offers two communications options: HART or PROFIBUS PA (Profile version 3.0, Class B). The transducer on the Probe LU is available as ETFE or PVDF to suit the chemical conditions of your application. As well, for applications with varying material and process temperatures, the Probe LU incorporates an internal temperature sensor to compensate for temperature changes. • Key Applications: chemical storage vessels, filter beds, liquid storage vessels 4/140 Siemens FI 01 · 2016 Seams 10° Beam angle SITRANS Probe LU mounting © Siemens AG 2016 Level Measurement Continuous level measurement - Ultrasonic transmitters SITRANS Probe LU ■ Technical specifications Process connection Mode of operation Measuring principle Ultrasonic level measurement Typical application Level measurement in storage vessels and simple process vessels Threaded connection 2" NPT [(Taper), ANSI/ASME B1.20.1] R 2" [(BSPT), EN 10226] or G 2" [(BSPP), EN ISO 228-1] Inputs Flange connection 3 inch (80 mm) universal flange Measuring range • 6 m (20 ft) model • 12 m (40 ft) model Other connection 0.25 ... 6 m (10 inch ... 20 ft) 0.25 ... 12 m (10 inch ... 40 ft) FMS 200 mounting bracket (see page 4/190) or customer supplied mount Display and Controls Frequency 54 kHz Interface Local: LCD display with bar graph Remote: Available via HART or PROFIBUS PA Outputs mA/HART • Range • Accuracy 4 ... 20 mA ± 0.02 mA PROFIBUS PA Profile 3, Class B Performance Configuration Using Siemens SIMATIC PDM (PC) or HART handheld communicator or Siemens infrared handheld programmer Memory Non-volatile EEPROM Resolution 3 mm (0.12 inch) Power supply Accuracy ± the greater of 0.15 % of range or 6 mm (0.24 inch) 4 ... 20 mA/HART Nominal 24 V DC with 550 maximum; maximum 30 V DC 4 ... 20 mA Repeatability 3 mm (0.12 inch) PROFIBUS PA Blanking distance 0.25 m (10 inch) 12, 13, 15, or 20 mA depending on programming (General Purpose or Intrinsically Safe version) Update time • 4/20 mA/HART version • PROFIBUS version 5s 5 s at 4 mA 4 s at 15 mA current loop Temperature compensation Built-in to compensate over temperature range Beam angle 10° per IEC 61158-2 Certificates and Approvals General Hazardous • Intrinsically Safe (Europe) • Intrinsically Safe (USA/Canada) Rated operating conditions Ambient conditions • Location • Ambient temperature • Relative humidity/ingress protection • Installation category • Pollution degree Indoor/outdoor -40 ... +80 °C (-40 ... +176 °F) Suitable for outdoor I 4 Medium conditions • Temperature at flange or threads • Pressure (vessel) -40 ... +85 °C (-40 ... +185 °F) 0.5 bar g (7.25 psi g) Design CSAUS/C, FM, CE, RCM Marine (only applies to HART commu- • Lloyd’s Register of Shipping nication option) • ABS Type Approval • Intrinsically Safe (International) • Intrinsically Safe (Brazil) • Non-incendive (USA) ATEX II 1G Ex ia IIC T4 Ga CSA/FM, Class I, Div. 1, Groups A, B, C, D; Class II, Div. 1, Groups E, F, G; Class III T4 SIR 13.0008X Ex ia IIC T4 Ga INMETRO Ex ia IIC T4 Ga FM Class I, Div. 2, Groups A, B, C, D T4 Handheld Programmer Intrinsically Safe Siemens handheld Infrared receiver programmer • Approvals for handheld programmer ATEX II 1GD / IECEx SIR 09.0073 Material (enclosure) PBT (Polybutylene Terephthalate) Ex ia IIC T4 Ga Degree of protection Type 4X/NEMA 4X, Type 6/NEMA 6/ IP67/IP68 enclosure Ex iaD 20 T135 °C Weight 2.1 kg (4.6 lb) Cable inlet 2 x M20 x 1.5 cable gland or 2 x ½" NPT thread or 1 x M20 x 1.5 and 1 x ½" NPT Material (transducer) Buna-N seal with ETFE (Ethylene Tetrafluoroethylene) or PVDF (Polyvinylidene Fluoride) FM/CSA Class I, II, III, Div. 1, Groups A, B, C, D, E, F, G T6 Ambient temperature -20 ... 50 °C (-5 ... 122 °F) Interface Proprietary infrared pulse signal Power 3 V lithium battery (non-replaceable) Siemens FI 01 · 2016 4/141 4 © Siemens AG 2016 Level Measurement Continuous level measurement - Ultrasonic transmitters SITRANS Probe LU Selection and Ordering data Article No. SITRANS Probe LU 2-wire, loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in open channels, storage vessels, and simple process vessels. 7ML52217 7 7 77 4 Order code Stainless steel tag [69 x 50 mm (2.71 x 1.97 inch)]: Y15 Measuring-point number/identification (max. 27 characters) specify in plain text Click on the Article No. for the online configuration in the PIA Life Cycle Portal.
