แบรนด์ไฟน์เทค EB5 ซีรี่ เครื่องส่งสัญญาณระดับแบบอาร์เอฟ แอตมิตแตนซ์

RF Admittance Level Transmitter utilizes the capacitance formed between the sensing probe
and the reference probe or the metal vessel wall to calculate the level of the medium inside
the vessel according to the capacitance theory that the capacitance and vessel are proportional
increased. When the probe is surrounding by the air, little capacitance (C ) is measured by the
equivalent capacitor, the capacitance increase gradually as computing media, the max. capacitance (C )
will be measured while the tank is full, the difference (dC) between C and C is proportional to the level.
(Recommend range dC =25 ~2000 pF)
