© Siemens AG 2015 Level Measurement Continuous level measurement – Ultrasonic transmitters SITRANS LU150 ■ Overview ■ Configuration SITRANS LU150 is a short-range integrated ultrasonic level transmitter. This general purpose, 2 wire, 4 to 20 mA loop powered transmitter is ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft). ■ Benefits • • • • • Easy to install, program, and maintain Accurate and reliable Sanitary models available Patented Sonic Intelligence echo processing Integral temperature compensation ■ Application The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications. SITRANS LU150 is easy to install and maintain, and can be quickly removed for cleaning as required by the food, beverage and pharmaceutical industries. The reliability of the level data is based on the Sonic Intelligence echo processing algorithms. A filter discriminates between the true echo and false echoes from acoustic or electrical noises and agitator blades in motion. The ultrasonic pulse propagation time to the material and back is temperature-compensated and converted into distance for display, analog output. • Key Applications: chemical storage vessels, filter beds, mud pits, liquid storage vessels, food applications Fill Pipe Rungs Seams 12º Beam Angle SITRANS LU150, mounting Siemens FI 01 · News 2015 4/1 © Siemens AG 2015 Level Measurement Continuous level measurement – Ultrasonic transmitters SITRANS LU150 ■ Technical specifications SITRANS LU150 Mode of operation Measuring principle Ultrasonic level measurement Input Measuring range 0.25 ... 5 m (0.8 ... 16.4 ft) Frequency 54 kHz Output • mA 4 ... 20 mA - Span Proportional/ inversely proportional - Max. load 600 in the loop at 24 V DC Power supply Supply voltage 12 ... 30 V DC, 0.1 A surge Max. power consumption 0.75 W (25 mA at 24 V DC) Certificates and approvals CE, CSAUS/C Accuracy • Error in measurement • Resolution • Temperature compensation • Echo processing Rated operation conditions • Beam angle • Ambient temperature - Standard - Metallic mounting • Max. static operating pressure Design • Weight • Material - Electronics enclosure - Transducer • Degree of protection • Process connection • Flange adapter • Cable inlet 4/2 0.25 % of measuring range (in air) 3 mm (0.125 inch) Built in Sonic Intelligence 12° -30 ... +60 °C (-22 ... +140 °F) -20 ... +60 °C (-4 ... +140 °F) Normal atmospheric pressure 1.3 kg (2.9 lb) PBT PVDF copolymer IP68 / NEMA 6 / TYPE 6 2" NPT [(Taper), ANSI/ASME B1.20.1] R 2" [(BSPT), EN 10226] or G 2" [(BSPP), EN ISO 228-1] 3" Universal, (fits DN 65, PN 10 and 3" ASME) 4" sanitary 1 inlet for M20, optional 1/2" NPT Siemens FI 01 · News 2015 Selection and Ordering data Article No. SITRANS LU150 Short-range integrated ultrasonic level transmitter, general purpose, 2 wire, 4 to 20 mA loop powered ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 meters (16.4 feet) 7ML52010 77 0 Click on the Article No. for the online configuration in the PIA Life Cycle Portal.
