Siemens' SITRANS LU150 is a short-range integrated ultrasonic level transmitter for use with liquids, slurries, and bulk materials in open or closed short-depth vessels (from 0.8 to 16.4 feet). This general purpose, two-wire, 4 to 20 mA loop powered transmitter features an integrated ultrasonic transducer is available in PVDF copolymer, making the LU150 suitable for a variety of applications. The SITRANS LU150 is an ideal replacement for the Milltronics Probe with 4-20 mA output. If you need HART communications, see the Siemens SITRANS Probe LU.
The new SITRANS LU180 has the same functionality as the LU150 plus intrinsically safe approval (CE cCSAus, ATEX, FM, CSA, IECEx, and NEPSI) for use in harsh environments.
Both SITRANS LU150 and LU180 include patented Sonic Intelligence echo processing algorithms to discriminate 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, and analog output.
