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 A capacitor, the capacitance increase gradua ly as computing media, the max. capacitance (C ) will be B measured while the tank is fu l, the difference (dC) between C and C is proportional to the level. A B (Recommend range dC =25 ~2000 pF
- 。After installation of the Admittance Level Transmitter on the top of tank, please make sure the cover of the transmitter is contacted with tank perfectly. Please avoid the grounding of panel meter to touch the tank wall.
- 。While the pamel meter is not supplied with a power supply, please prepare a 24V power supply for use.
- 。The max cable length is depends on the max resistance .Maximum resistance is not to exceed (Vs-22)X 5002 to ensure the accuracy of measurement.
- 。Make sure to separate the signal cable with other big power cables (such as pump, conveyor and solenoid valve)while wiring. Before turning on power, make sure all wirings are correct.
- 。Connect isolation cable with GND of power.
- 。If there is heater or other electric device in the application, contacting the cover of the transmitter and tank can decrease EMI.
