| Fine-Tek EBX RF-Admittance Level Transmitter |
| ● GENERAL DESCRIPTION |
| Type | RF Admittance (capacitance) Level Transmitter |
| Principle | Measures the capacitance formed between the sensing probe and the reference probe / metal vessel wall. Capacitance increases as the medium level rises; the difference (dC) between empty (CA) and full (CB) capacitance is proportional to level. Recommended range dC = 25~2000 pF. |
| Output Signal | 4~20mA two-wire loop powered; HART digital output (option); local LCD display |
| Product Families Covered | Standard Type: EB5200/EB5201/EB52A0/EB52A1 (Rod), EB5300/EB5301/EB53A0/EB53A1 (Cable), EB5400/EB54A0 (Two Rod), EB5500/EB55A0/EB5501 (Anti-wave Tube).

| ● WIRING / CONNECTIONS |
| Power Supply | If the panel meter is not supplied with power, prepare a 24V power supply for use. |
| Max. Cable Length | Depends on max. loop resistance; resistance must not exceed (Vs-22) x 50Ω to ensure measurement accuracy. |
| Cable Routing | Separate signal cable from other high-power cables (pumps, conveyors, solenoid valves). Verify all wiring before powering on. |
| Grounding | Transmitter cover must contact the tank perfectly; avoid panel meter grounding touching the tank wall. Connect isolation cable to GND of power. Process connection should be grounded during installation. |
| EMI Mitigation | If a heater or other electric device is present in the application, contacting the transmitter cover to the tank can reduce EMI. |
| Installation Notes | Use Two Rod Probe type for non-conductive tanks, or install a concentric metal pipe shield (with vent hole) around the probe. Keep rod/wire probe parallel to and clear of the tank wall. Use a Coating Probe type for conductive media (bare electrode will not work correctly). Housing cover and conduit opening must be sealed/tightened to prevent moisture ingress. For non-conductive powder/granule media in large tanks, fix the wire probe to the bottom of the tank. A pipe shield is recommended if an agitator is present. |

| * Discrepancy in source: EB1743 is labeled “FEP Coating” in the dimensional drawing, but its printed order-code suffix (14) matches the Probe Material legend code for PFA, not FEP (03). Printed exactly as it appears in the source PDF; verify with Fine-Tek before ordering. “□” = digit filled in per the code structure below (connection, etc.). |
