PRODUCT DISCONTINUED - REPLACED BY THE LUT400, OR THE MultiRanger 200, OR THE HydroRanger 200, OR THE LR560 (APPLICATION DEPENDENT)
The SITRANS LU02 is a dual point ultrasonic long-range level transmitter for liquids and solids in one or two vessels up to 60 m (200 ft). It will measure liquids, solids or a combination of both in one or two vessels of different sizes, shapes and configurations up to a distance of 60 m (200 ft). The system uses ultrasonic technology to measure level, space, distance, volume or average/differential. Transducers can be mounted up to 365 m (1200 ft) from the monitor.Readings are displayed in user-selectable linear engineering units on the backlit LCD. The LU 02 ultrasonic transmitter features patented Sonic Intelligence® echo processing software which gives superior reliability
The Siemens LU02 features an onboard communications port that automatically configures for RS-232, RS-485 or bi-polar current loop. Siemens SmartLinx® interface modules can be used to connect to a DCS or PLC. This gives the user remote 2-way communication and full parameter access. Modules for popular industrial buses can be factory installed or added later to meet changing needs. As the unit doesn't require an external gateway, hardware and cabling costs are reduced.. ( Handheld programmer shown is an accessory and must be ordered
separately).
