SITRANS LU150/LU180

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). SITRANS LU180 is a short-range integrated ultrasonic level transmitter. This intrinsically safe (ATEX, CSA, FM, IECEx, NEPSI), 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). The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications. SITRANS LU150/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.

What precision and reliability mean for your applications

Your facility is a busy place - and materials and conditions inside your tanks/vessels/wells are always changing. Siemens ultrasonics selects the correct echo after every measurement, giving you stable readings while still allowing rapid response to actual changes in the material level. The result? Operations are more cost-effective. Inventory monitoring is always precise. Processes can be better controlled. And expensive spill cleanups can be avoided.
