SITRANS Probe LU
Process Instrumentation
Ultrasonic Level Transmitter
SITRANS Probe LU is a 2-wire loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in open channels, storage vessels and simple process vessels. The SITRANS Probe LU is ideal for level monitoring in the water and wastewater industry and chemical storage vessels. The range of SITRANS Probe LU is 6 or 12 m (20 or 40 ft).

Specifications
The Probe LU ultrasonic level transmitter provides unmatched reliability using Auto False-Echo Suppression for fixed obstruction avoidance, as well as an improved signal-to-noise ratio and improved accuracy of 0.15% of range or 6 mm (0.25"). SITRANS Probe LU includes Sonic Intelligence® signal processing from the field-proven Probe and incorporates new echo processing features and the latest micro-processor and communications technology. The Probe LU offers two communications options: HART or PROFIBUS PA (Profile version 3.0, Class B). The transducer on the Probe LU is available as ETFE or PVDF for harsh chemical conditions, as well as for applications with varying material and process temperatures. The Probe LU incorporates an internal temperature sensor to compensate for temperature changes.
Key Applications: chemical storage vessels, filter beds, liquid storage vessels.
Supplementary components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions.
Don’t forget that the safest engineered level measurement solution includes switches for back-up, overfill, low level and dry run protection.
