The Emerson LevelDatic LD80S is a high-precision electro-pneumatic multi-point level measurement system designed by Emerson for marine and industrial tank applications. Based on hydrostatic pressure measurement principle, it adopts bubbling pneumatic detection and 1:1 pneumatic pressure conversion technology to accurately collect liquid level, ship draught, ballast tank, fuel tank and bilge water level data. With no moving parts or internal wiring inside the tank, the system features reliable corrosion resistance and easy maintenance, delivering high repeatability, negligible hysteresis and low temperature drift.
Equipped with self-diagnosis alarm, quick test loop and pre-calibrated replaceable sensors, the LD80S supports simultaneous multi-point measurement and is widely used in various ships, offshore platforms and industrial tank level monitoring scenarios. This model is discontinued for new sales and only spare parts & maintenance services are available, serving as a classic mainstream level measuring device for marine industry stock assets.
-
Superior Measurement Stability: Adopting hydrostatic pneumatic measurement principle, the system features negligible hysteresis, low temperature dependency and excellent repeatability, ensuring stable long-term measurement data and meeting marine high-precision level monitoring standards.
-
Tank-free Maintenance Design: All sensors and core components are installed in external cabinets with no moving parts or wiring inside tanks, avoiding medium corrosion and impact damage and greatly reducing on-site maintenance difficulty.
-
Dual-mode Wide Adaptability: Supporting both bubbling air supply mode and 1:1 pneumatic pressure conversion mode, it adapts to various tank media including ballast water, fuel oil, heavy oil and fresh water.
-
Intelligent Self-diagnosis Protection: Built-in complete self-diagnosis system supports fault alarm output, real-time monitoring of circuit and sensor abnormalities, and early hidden danger warning to ensure continuous and reliable system operation.
-
Fast & Convenient Maintenance: Equipped with dedicated quick-test interface for one-click circuit inspection and pipeline purging. Pre-calibrated sensors support direct plug-and-play replacement without on-site recalibration.
-
High Adaptability for Marine Conditions: Specially designed for harsh working conditions of ships and offshore platforms, it features vibration resistance, moisture resistance and marine corrosion resistance, adapting to complex and variable offshore environments with long service life.
