Description
The LM80 is a high performance laser transmitter that accurately measures level, distance and position over long ranges in extreme environments. It is a non-contact, level measuring instrument designed for granular solid materials and opaque liquids. Based on pulsed laser technology, the LM80 embodies speed and accuracy in a single, easy to use and install product. Whether measuring a few meters into the confined space of a crusher, or to the bottom of the tallest silo, the LM80 with its laser pointer and long range is the plug-and-play solution to level measurement. The LM80 features advanced timing and sophisticated signal processing for pinpoint accuracy at up to 100 m (330 ft.) for level applications and up to 150 m (500 ft.) for positioning applications. FEATURES: • Maintenance free, non-contact continuous level sensor • Range up to 100 m (330 ft) for level applications • Range up to 150 m (500 ft) for positioning applicationsEasy and intuitive setup • No calibration required • Continuous level monitoring for granular solid materials and opaque liquids • Measures solids and opaque liquids at any angle • Last Pulse Detection for Measurement with Light and Moderate Dust • Built-in laser pointer for accurate alignment in narrow or tall vessels • Auto-ranging to measure all levels • Available non condensing heated optics prevent condensation issues • No Beam Divergence = No False Echoes • Rugged and Robust Aluminum Enclosure • CSA, ATEX and IECEx potentially explosive atmosphere ratings OPTIONS: • Many mounting options • Configuration device (LCD2) • Non-condensing optics (heated lens) • Stainless steel housing • Tri-clover interface
The LM80 Level Transmitter has required the extraction anduse of natural resources for its production. Therefore, theLM80 Level Transmitter may contain hazardous substancesthat could impact health and environment. In order to avoiddissemination of these hazardous products into the environment and also to reduce the extraction and protect our naturalresources, ABB inc. strongly recommends to use appropriaterecycling systems in order to make sure materials used to produce your equipment are reused or recycled in a sound way. For European countries, at the end of life of the analyzer, contact your distributor before disposing of your equipment. The LM80 laser level transmitter is not subject to the EuropeanWEEE directive based on the exemption for fixed industrial installations however most of it's components are easily recyclable. The LM80 falls into this category by virtue of the fact thatit is meant to be permanently installed by a qualified installeron industrial vessels in locations like petrochemical complexes, ore processing sites and food processing sites in order tomeasure the level of the content. The LM80 is not meant tobe moved from site to site and serves no useful stand-alonepurpose. LM80 laser level transmitter key features – Narrow beam for direct targeting – Visible aiming laser – Long distance measuring capability– Dust and gas ignition proof housing – Measurements are not affected by the angle or roughness of the surfacebeing measured – Rapid response to moving levels and positions – Immunity to nearby objects – Immunity to vessel shape – Immunity to the material of construction of the vessel – Ability to reject momentary obstacles – User selectable program options – Below are mechanical dimensions:
The LM80 laser level transmitter is an optical, line of sightdevice that is used for non-contact distance measurement.There must be no obstacles directly in the beam path.
The LM80 laser level transmitter measures in engineering units(feet or meters) so there is no need for calibration prior toinstallation. The instrument can simply be aimed directly towards an object and it will measure the real physical distancefrom its face. Any special settings required by the user may beloaded into the device inside the work area or workshop priorto mounting the LM80 laser level transmitter outside.
The product is designed to withstand many industrial environmental conditions. However, a few handling precautionswill ensure reliable operation of the unit for extended periodsof time.
– DO NOT DROP THE INSTRUMENT
– Remove dirt from the lens with air or if not sufficient, cleanwith alcohol and optical wipes.
– Do not install or connect with the power on.
– Do not open the instrument compartment or expose theinternal electronics to water or dirt.
– Ensure that the cable glands or conduits are tight afterconnecting the external cable.
– Ensure that the lid to the terminal compartment is tightafter connections have been made.
– Do not point the instrument at the sun.
– Do not open or modify the instrument.
– Store in a cool dry place.
