© Siemens AG 2016 Level Measurement Continuous level measurement – Ultrasonic transmitters SITRANS LU180 ■ Overview ■ Configuration SITRANS LU180 is a short-range integrated ultrasonic level transmitter. This intrinsically safe, 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 LU180 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 LU180 mounting Siemens FI 01 · News 2016 4/1 © Siemens AG 2016 Level Measurement Continuous level measurement – Ultrasonic transmitters SITRANS LU180 ■ Technical specifications Mode of operation Measuring principle Ultrasonic level measurement Input Measuring range 0.25 ... 5 m (0.8 ... 16.4 ft) Frequency 54 kHz Selection and Ordering data Article No. SITRANS LU180 Short-range integrated ultrasonic level transmitter, intrinsically safe, 2 wire, 4 to 20 mA loop powered ideal for liquids, slurries, and bulk materials in open or closed vessels to 5 m (16.4 ft). 7ML52020 77 0 Click on the Article No. for the online configuration in the PIA Life Cycle Portal.
