SITRANS LU150/LU180 Ultrasonic Level Transmitter
Brand: Siemens AGSITRANS 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).
SITRANS LU150/LU180 ultrasonic level transmitters are easy to install and maintain, and can be removed quickly for cleaning as required by the food & beverage and pharmaceutical industries.
The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications.
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.
