Design & Functionality
The level switch incorporates a specialized sensing structure consisting of a main probe, guard section, insulation layer, and grounding electrode. Radio frequency signals are applied to the sensing probe to monitor admittance changes when materials reach the detection point.
The guard section isolates the sensing probe from unwanted interference caused by product buildup. This design ensures the system measures only the true admittance change between the probe and tank wall. As a result, the device maintains measurement accuracy while eliminating false switching caused by coating or sticky materials.
Total Crossed Beams
The sensing configuration ensures reliable signal transmission within the tank environment. The guarded probe design maintains signal integrity and prevents interference from surrounding material adhesion, ensuring consistent switching performance during continuous operation.
Beam Pitch Options
Different probe configurations allow the level switch to adapt to multiple installation requirements. These options enable accurate monitoring in compact vessels, tall silos, and large storage tanks used for bulk solids or liquid storage processes.
Intrinsic Synchronism
The internal signal system synchronizes the sensing probe and guard electrode signals. This synchronization isolates measurement signals from environmental interference, ensuring stable operation in high-temperature and heavy process conditions.
Operational Advantages
Using RF admittance technology provides several advantages compared to conventional level switches. The device operates reliably even when exposed to sticky or viscous materials, which typically cause issues with standard capacitance sensors.
Its flexible installation options, high reliability, and low maintenance requirements make it suitable for long-term industrial operation. With robust performance across different material types and process environments, this level switch improves operational safety, reduces downtime, and enhances process automation efficiency.
