The ABB LT2005-S/SP19 is an original industrial high-precision closed-loop Hall-effect transducer, widely marketed as a high-stability level & current monitoring sensor for global DCS and PLC automation systems, fully in stock at our overseas warehouse with standardized 12-month official warranty for all genuine brand-new units, excluding refurbished, duplicate or second-hand spare parts. Designed combining ABB’s mature industrial measurement technology and classic LEM closed-loop sensing core, this modular transducer achieves dual-function monitoring of equipment current fluctuation and auxiliary liquid level auxiliary feedback in heavy industrial scenarios, becoming a mainstream replacement spare for petrochemical, thermal power, new energy and wastewater automation upgrading projects worldwide.
Built around advanced closed-loop compensated Hall sensing principle, the core hardware of LT2005-S/SP19 ensures ultra-high measuring accuracy and outstanding linearity, the core indicator for high-precision industrial monitoring. Its nominal primary measuring current reaches 2000A RMS with an overload tolerance up to 3000A peak current, overall measurement precision controlled within ±0.3% full scale and temperature drift suppressed to extremely low ppm level, avoiding data deviation caused by ambient temperature variation in long-time continuous production operation. Equipped with built-in non-loss signal conversion circuit, the transducer converts AC, DC and pulse mixed input signals into standard 400mA rated secondary output signal with fixed transformation ratio 1:4000, which can be directly matched with ABB AC800M, Symphony Plus DCS and mainstream third-party PLC modules without extra signal converter modification, greatly simplifying on-site wiring and debugging work. Optimized internal circuit layout shortens response time to microsecond grade and expands effective working frequency bandwidth, enabling real-time capture of instantaneous current and liquid level sudden changes inside production tanks and power cabinets, effectively preventing equipment overcurrent overflow and liquid tank overflow risks.
In electrical and environmental specification parameters, LT2005-S/SP19 adopts dual bipolar DC power supply of ±15VDC ~ ±24VDC with low standby power consumption to cut long-term factory operation cost. Certified working ambient temperature ranges from -25℃ to +70℃, storage temperature spans -40℃ ~ +85℃, resisting 5%~95% non-condensing humidity and severe industrial electromagnetic interference from frequency converters, high-voltage cabinets and large mechanical equipment; its UL94-V0 flame-retardant plastic shell passes CE, UL and RoHS global industrial certification, adapting dusty, corrosive and high-vibration harsh workshop surroundings of chemical plants, steel mills and new energy power stations. The central hollow aperture size is 56mm standard inner diameter for primary cable penetration, supporting multi-strand thick wire through-type non-contact installation without cutting off main power circuit during retrofitting. Compact integrated dimension is 150×100×60mm with net weight around 0.8kg, reserved fixed mounting foot for direct panel or DIN cabinet installation to fit limited-space electrical cabinet layout.
Rich compatibility and wide industry coverage highlight its market competitiveness. Predefined standard signal output seamlessly connects ABB HART protocol level transmitters, field liquid level floating sensors and upper SCADA monitoring platform to realize unified real-time data collection of tank liquid depth and loop operating current. Major applicable fields include photovoltaic & wind power converter cabinets, industrial servo drive control, UPS uninterruptible power supply, welding power equipment, petrochemical storage tank liquid level monitoring and municipal sewage treatment pool level control, also serving as core monitoring component for metallurgy smelting production lines.
