LEDAER UMF Series
RF Admittance Level Transmitter: Accurate, Drift-Free Measurement for Challenging Slurries & Solids
📌 Overview
The UMF Series is the ultimate solution for measuring the level of challenging liquids, slurries, and solid granules. Unlike traditional capacitance sensors, RF Admittance technology features a unique “Active Shield” design that allows the sensor to ignore the effects of material buildup (coating) on the probe. Whether dealing with sticky coal ash, viscous polymers, or aggressive slurries, the UMF series ensures accurate, drift-free measurement.
✨ Key Features & Advantages
Anti-Coating Tech
Effectively eliminates measurement errors caused by material clinging or “caking” onto the probe.
Universal Media
Equally effective for Liquid Level (oil, acid) and Solid Material Level (powder, grains, dust).
Extreme Resilience
Operates in high-pressure (up to 10 MPa) and extreme heat (up to +800°C) environments.
Solid-State Design
Zero mechanical components ensure extreme durability in high-vibration or high-wear settings.
