Lidec Liquid Limit Switch
What Is It?
Lidec is a no-moving-parts liquid limit switch designed for point level detection in storage and service tanks. It provides a fail-safe, low-maintenance solution for high level and overfill protection across a wide range of applications.
Key Applications:
- High level alarms in product storage tanks (single or dual limit detection)
- Service tanks with varying liquid types, regardless of conductivity
- Critical safety systems, where reliable overfill detection is essential
Why Choose Lidec?
- No moving parts = virtually zero mechanical wear
- Insensitive to density, temperature, or pressure changes
- No calibration required – fast and simple commissioning
- Stainless steel housing allows direct on-deck mounting
- Compact sensor diameter minimizes tank wall/roof intrusion
- Modular design enables easy on-site repairs and spare part replacement
How Does It Work?
Lidec operates using a patented surface wave propagation principle inside a stainless steel probe. Unlike vibrating or float-based systems, this is a completely static detection method.
A built-in self-monitoring function continuously checks sensor health. The fail-safe design ensures any malfunction (such as power failure or sensor damage) is detected and reported automatically—no manual testing or regular cleaning required.
This makes Lidec highly suited for use in mission-critical safety systems for overfill protection and level control.
What Problems Does It Solve?
- Prevents product loss and environmental hazards caused by undetected overfills
- Eliminates calibration requirements, simplifying installation and operation
- Reduces maintenance costs with a no-moving-parts design
- Supports easy on-site repairs for uninterrupted performance
- Ensures reliability through positive safety (malfunctions trigger alarms)
