LI-420 Magnetic Indicator
The LI-420 Magnetic Liquid Level Indicator provides high-precision fluid tracking for transformer conservator tanks. Engineered for accuracy, this robust gauge ensures safe and reliable oil level visualization.
LI-420 Specifications
Build Type
Custom alloy aluminum housing paired with UV-resistant polycarbonate viewing glass for industrial grade durability.
Float System
Advanced magnetic coupling technology provides a hermetically sealed interface which prevents all liquid migration.
Signal Output
Configurable dual SCADA microswitches alongside a high-resolution 4-20mA loop for integrated remote monitoring.
Mounting Options
Versatile radial or axial mounting configurations designed to accommodate diverse tank geometries and depths.
Temperature
Operational tolerance across a wide thermal range of -40°C to +100°C for extreme environmental applications.
Precision
Leak-Free Isolation
Utilizes magnetic coupling to separate the indicator from the fluid, eliminating potential oil leak paths.
High Contrast
Designed with a high-visibility dial face to ensure local readings are legible from long ground distances.
Alert Systems
The integrated switch set allows for automated low or high-level alarms to protect transformer windings.
Rugged Build
Weather-proof construction ensures long-term reliability in utility-scale outdoor substation equipment.
