Working Principle:-

Admittance is a static level sensor with no moving parts. Its sensing parts are:-

• Earth extension (body) Compensation shield Sensing rod
• These parts form three capacitance's
• Shield earth capacitance Shield sense capacitance Sense earth capacitance
• A Sine wave of high frequency is fed into both sensing rod as well as compensation shield.
• Voltage at shield is equal to voltage at sense, no effective current flows between sense and shield.
• This removes shield-sense capacitance from the measurement, shield-earth capacitance is ignored by circuit.
• This removes the effect of material coating on probe.
• Material is detected by measuring sense-earth capacitance.
