For sticky materials, the cheapest level switch is often not the most reliable option. RF admittance level switches are more suitable when buildup, coating and false signals are common problems. Correct probe selection, installation position and electrical compatibility are essential for long-term stable operation. Shao Level provides RF admittance level switches, rotary paddle level switches, vibrating fork level switches and other industrial level measurement products for sticky powders, slurry, tanks, silos, hoppers and automation systems.

If your application involves clean and dry materials, a standard capacitance or rotary paddle level switch may be sufficient. However, if your process includes sticky materials, dust, coating or unstable conditions, an RF admittance level switch is a more reliable choice. Choosing the correct level switch can significantly improve system stability, reduce maintenance and prevent false alarms in industrial processes.

RF admittance level switches are often better for difficult materials because they handle coating, dust, and unstable process conditions more effectively. Their value is highest where process interruptions and false signals create real operational cost.
