ABB LT2005‑S/SP19 – Harsh Environment Level Transmitter

Product Overview

The ABB LT2005‑S/SP19 is a heavy‑duty, submersible level transmitter engineered for harsh industrial environments where extreme temperatures, moisture, corrosion, vibration, and electrical noise are common. Built on hydrostatic pressure sensing technology and backed by ABB’s industrial reliability, it delivers stable, accurate, and drift‑free liquid level measurement in tanks, pits, and vessels across demanding process industries.

Key Features for Harsh Environments

✅ Extreme Environmental Resistance

• Operating temperature: −30 °C to +60 °C (withstands freezing and high heat)
• Protection class: IP66/IP68 – dust‑tight, waterproof, and fully submersible
• Humidity tolerance: 5–95% non‑condensing; anti‑condensation design for humid enclosures
• Vibration & shock resistance: reinforced housing, no moving parts, ideal for pumping stations and vibrating machinery zones

✅ Corrosion & Chemical Compatibility

• Wetted materials: 316L stainless steel / PVDF (resists acids, alkalis, oils, and wastewater)
• Suitable for corrosive, viscous, or dirty liquids in chemical, petrochemical, and wastewater plants

✅ High Precision & Stability Under Stress

• Accuracy: ±0.1% FS with excellent repeatability
• Built‑in temperature compensation minimizes drift in fluctuating temperatures
• EMC compliance: IEC 61326, CISPR Class B – immune to electrical noise in heavy‑duty plants
• Overpressure, short‑circuit, reverse‑polarity protection for reliable 24/7 operation

✅ Rugged & Maintenance‑Free Design

• Compact, submersible construction with standard process connections (e.g., M56×3)
• No moving parts = minimal wear, long service life, and low maintenance
• 4–20 mA output (HART optional) for seamless integration with DCS/PLC and remote diagnostics
