  • Page 2: Specifications

    NOTE: Liquids with a conductivity value > 100 µU are fine if coating is not an issue. Liquids with a dielectric constant less than 20 may not be reli- ably detected by an LVP-51 series level switch, depending on conditions.
  • Page 3: Safety Precautions

    LVP-51 series Non- Intrusive RF Capacitance level switch from Omega. Please refer to the part number located on the switch label to verify the exact model which you have purchased. User’s Responsibility for Safety: Omega manufactures a wide range of liquid level sensors and tech- nologies.
  • Page 4: Installation

    Ground Signal Outputs (Relay switching): Allows the sensor to switch a small load on or off directly, using an internal 1 A relay (60 VAC/60 VDC). All models, LVP-51 series- _005, use the relay and features 4 wires (red, black, white and green) and a shield wire.
  • Page 5: Wiring As A P-Channel Or N-Channel Output

    VDC or VAC power source. LVP-51 series requires 12 - 36 VDC power to operate the sensor and switch the relay. All illustrations below identify a Dry switch state as the normal position of the relay. Switching a Normally Open DC Load: The Red wire connects to Positive (+) of the power supply and the Black wire connects to Negative (-).
  • Page 6: Testing The Sensor

    4. Empty state: With the tank drained to a point no closer than 6 inches below the bottom of the sensor, set the switch to the Empty position (left). Set the Empty trimpot as in Step 3. 5. After completing calibration, make sure to return the switch to the center position.
