Working Principle
The Heavy Duty RF Admittance Level Switch operates by measuring capacitance changes to determine the presence or absence of a medium (liquid or solid).
- Air Mode: When the sensing rod is exposed to air, the capacitance remains stable.
- Material Contact: As the medium rises and contacts the sensing rod, the dielectric constant alters the capacitance.
- Threshold Activation: A high-frequency sine wave is applied to both the sensing rod and guard electrode, creating an electrostatic field. The system continuously monitors capacitance changes, and when a predefined level is reached, the switch activates alarms or controls pumps.
This precise detection mechanism ensures reliable level monitoring, operational efficiency, and safety in demanding industrial applications.
