LEDAER UMD Series
Capacitance Level Transmitter: High-Performance Continuous Measurement for Challenging Environments
📌 Overview
The UMD Series is a high-performance continuous level measurement solution designed for challenging industrial environments. By measuring the change in capacitance between the probe and the container wall, it provides stable and accurate level data. With its “no moving parts” design and exceptional pressure resistance, it is a reliable alternative where mechanical float-based sensors might fail.
✨ Key Features & Advantages
Extreme Pressure Duty
Specially engineered to withstand working pressures up to 32MPa for high-pressure process vessels.
Broad Temp Range
Operates reliably from cryogenic -196°C up to 250°C.
Maintenance-Free
Solid-state sensor with no mechanical wear, significantly reducing long-term costs.
High Stability
Low drift rate of ≤ 0.2% FS/year ensures consistent measurement over time.
