ABB LT2005-S/SP19 Liquid Level Monitoring Module | High Stability

Product Overview

The ABB LT2005-S/SP19 is a professional liquid level monitoring module based on hydrostatic pressure measurement. Focused on high operational stability, it provides continuous, reliable liquid level detection for industrial tanks, pools and vessels. Optimized for long-term on-site operation, it features minimal measurement drift, strong anti-interference capability and durable build, and can be seamlessly connected with DCS, PLC and other automation systems. It is widely applied in water treatment, chemical, power, petrochemical and other process industries.

Key Features

1. Superior Long-Term Stability Equipped with high-precision sensing components and built-in temperature compensation circuit. It effectively offsets measurement errors caused by temperature fluctuation, ensuring consistent readings during 24/7 continuous operation. Frequent recalibration is not required, which greatly improves monitoring reliability.
2. Reliable Measurement Performance High overall accuracy and excellent repeatability. It delivers stable and accurate data for various liquid media, fully meeting the precision control demands of industrial production and inventory management.
3. Strong Environmental Adaptability Rated IP66/IP68, the module is dustproof, waterproof and submersible. It works steadily within -30°C to +60°C, and tolerates 5%~95% non-condensing humidity. Complying with EMC standards, it resists on-site electromagnetic interference.
4. Standard Signal & Flexible Communication Adopts universal 4-20mA analog output, with optional HART protocol. It supports remote parameter configuration, data reading and fault diagnosis, enabling easy integration into existing automation architectures.
5. Corrosion Resistance & Low Maintenance Wetted parts are made of anti-corrosion materials, suitable for water, oil and common chemical liquids. There are no moving parts inside, so wear and failure risks are low. It features long service life and little routine maintenance.
6. Easy Installation & Commissioning Compact structure with standard process connectors. The submersible installation method is simple and efficient, helping users save installation time and engineering costs.
