Description

The SITRANS LU180 is an ultrasonic level monitor combining sensor and electronics in a single
package. It is designed to measure liquid levels in open or closed vessels. The process part
(sensor) is PVDF, allowing the SITRANS LU180 to be used in a wide variety of industries,
especially food and chemical.
The sensor houses the ultrasonic transducer and temperature sensing element. The SITRANS
LU180 emits a series of ultrasonic pulses from the transducer. Each pulse is reflected as an
echo from the material and sensed by the transducer. The echo is processed by the SITRANS
LU180 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. The time for the pulse to travel to the material
and back is temperature compensated and then converted into distance for the mA output.
