SITRANS LU01 Ultrasonic Level Controller (DISCONTINUED)
- Automatically Converses Automatic level-to-volume conversion for standard or custom tank shapes
- Superior Reliability Features patented Sonic Intelligence echo processing software
- Ultrasonic Controller Single-point, long-range level monitoring up to 60m (200ft)
Overview
PRODUCT DISCONTINUED - REPLACED BY THE LUT400, OR THE MultiRanger 200, OR THE HydroRanger 200, OR THE LR560 (APPLICATION DEPENDENT)
The Siemens SITRANS LU01 is an ultrasonic long-range level controller for solids and liquids in a single vessel measuring up to 60 m (200 ft). The system consists of a SITRANS LU01 monitor linked to a non-contact ultrasonic transducer that can be mounted up to 365 m (1200 ft) away. The LU01 features patented Sonic Intelligence® echo processing software for superior reliability and can measure distance, level or volume.
An on-board communications port automatically configures for RS-232, RS-485 or bi-polar current loop, and a backlit LCD displays readings in user-selectable linear engineering units. The LU 01 will connect to a PLC or DCS using Siemens SmartLinx® interface modules, giving you remote 2-way communication and full parameter access. Modules for popular industrial buses can be factory installed or added later to meet changing needs. The unit does not require an external gateway which reduces hardware and cabling costs. (Handheld programmer shown is an accessory and must be ordered separately)
