© Siemens AG 2015 Level Measurement Continuous level measurement - Ultrasonic controllers SITRANS LU01 and LU02 ■ Overview ■ Overview 4 The SITRANS LU01 is an ultrasonic long-range level controller for liquids and solids in a single vessel up to 60 m (200 ft). Handheld programmer shown is an accessory and must be ordered separately. ■ Benefits ■ Benefits • Single point, long-range level monitoring • Easy to install; easy to program using removable infrared keypad (optional) • Compatible with all EchoMax transducers • Backlit LCD display with reading in standard engineering units • Automatic level-to-volume conversion for standard or custom tank shapes • Dolphin Plus compatible • High/low alarms ■ Application The system consists of a SITRANS LU01 monitor linked to a noncontacting ultrasonic transducer that can be mounted up to 365 m (1 200 ft) away. The SITRANS LU01 will measure distance, level or volume, and it features Sonic Intelligence echo processing software for superior reliability. Readings are displayed in user-selectable linear engineering units on the backlit LCD. Modules for popular industrial buses can be factory installed or added later to meet changing needs. No external gateway is required, reducing hardware and cabling costs. • Key Applications: chemical storage, liquid storage, bulk solids storage (gravel, flour bins, grains, cereals), plastic pellets 4/160 The SITRANS LU02 is a dual point ultrasonic long-range level controller for liquids and solids in one or two vessels up to 60 m (200 ft). Handheld programmer shown is an accessory and must be ordered separately. Siemens FI 01 · June 2015 • Dual point, long-range level monitoring • Easy to install; easy to program using removable infrared keypad (optional) • Compatible with all EchoMax transducers • Backlit LCD display with reading in standard engineering units • Automatic level-to-volume conversion for standard or custom tank shapes • Dolphin Plus compatible • High/low alarms ■ Application SITRANS LU02 will measure liquids, solids or a combination of both in one or two vessels of different sizes, shapes and configurations up to 60 m (200 ft). The system uses ultrasonic technology to measure level, space, distance, volume or average/differential. It features Sonic Intelligence echo processing software for superior reliability. Transducers can be mounted up to 365 m (1 200 ft) from the monitor. Readings are displayed in user-selectable linear engineering units on the backlit LCD. • Key Applications: chemical storage, liquid storage, bulk solids storage (gravel, flour bins, grains, cereals), plastic pellets, tripper car © Siemens AG 2015 Level Measurement Continuous level measurement - Ultrasonic controllers SITRANS LU01 and LU02 ■ Technical specifications Mode of operation Measuring principle Ultrasonic level measurement Measuring range 0.3 ... 60 m (1 ... 200 ft) Measuring points SITRANS LU01: Max. one point; SITRANS LU02: Max. two points Output signal Ultrasonic transducer EchoMax series, ST-H transducers Relays 4 SPDT Form C relays, rated at 5 A at 250 V AC, resistive load mA output • Max. load • Resolution • Outputs 0/4 ... 20 mA, optically isolated 750 Ω, isolated, 30 V 0.1 % of range SITRANS LU01: Max. one mA output SITRANS LU02: Max. two mA outputs Accuracy Selection and Ordering data Article No. SITRANS LU01/LU02 Single or dual point ultrasonic long-range level monitoring system for liquids and solids, and ranges up to 60 m (200 ft). 7ML5004- Click on the Article No. for the online configuration in the PIA Life Cycle Portal.
