SIEMENS SITRANS Probe LU Series Ultrasonic Level Transmitter

BENEFITS

Offering a range of 6 or 12 meters (20 or 40 feet), the SITRANS Probe LU utilizes Sonic Intelligence and Auto False Echo Suppression to ensure accurate measurements and fixed obstruction avoidance, with an impressive accuracy of 0.15% of range or 6 mm (0.25 inches), providing unmatched reliability.

Equipped with PROFIBUS PA (Profile version 3.0, Class B) communication capabilities, the Probe LU ensures seamless integration into your process control system.

The transducer options for the Probe LU include ETFE or PVDF to accommodate varying chemical conditions, while an internal temperature sensor compensates for temperature changes in applications with fluctuating material and process temperatures.
