Page 5: Introduction
Please note the following: • The user is responsible for all changes and repairs made to the device. • All new components must be provided by Siemens. • Restrict repair to faulty components only. • Do not re-use faulty components. -
Page 6: Description
The echo is processed by the SITRANS LU150 using Siemens' proven ‘Sonic Intelligence’ techniques. Filtering is applied to help discriminate between the true echo from the material, and false echoes from acoustical and electrical noises and agitator blades in motion. -
Page 7: Installing And Mounting
Installing and mounting Environmental The SITRANS LU150 should be mounted in an area that is within the temperature range specified, and that is suitable to the housing rating and materials of construction. It is advisable to keep the device away from high voltage or current runs, contactors and SCR control drives. -
