Liquid Level tab

General

• Sensor height – The height (mm) of the sensor measurable stack-up. The range – 30.00-422.5, default – 100.00.
• Sensor width – The width (mm) of the entire sensor stack-up. The range – 20.00-60.00, default – 35.00.
• Liquid – Select whether the liquid is Ungrounded or Grounded. Default – Ungrounded.
• Ground offset – The spacing gap (mm) between the outer ground traces and the edge of the sensor area. The range – 0.5-15, default – 0.50.

Extended sensor height

The extended sensor height improves the accuracy near the bottom of calculated levels.

• Sensor bottom offset – The height of the measurement offset. The range – 0-99.99, default – 12.00.
• Total height – Read-only. The total height of the sensor.

Front layer

Select the relevant check box to use the parameter as an input parameter.

• Number of electrodes – The total number of electrodes. The range – 3-32.
• Electrode width – The horizontal width (mm) of each electrode. The range – 1-59.99.
• Ground width – Read-only. The width (mm) of the ground traces.
• Edge shift – Read-only. The edge shift (mm) area on the top and bottom electrodes. This value can be negative.
• Sensing pad gap – The space (mm) between the electrodes. The range – 0.1-10.
• Sensor-ground gap – The horizontal space (mm) between the electrodes and neighboring ground traces. The range – 0.1-10.
• Electrode height – Read-only. The height (mm) of an electrode when measured at a single point on the horizontal axis.
• Tilt – Read-only. The distance (mm) between the highest and lowest points of the tilted edge of an electrode.

Back layer

• Trace width – The width (mm) of the trace, which connects some segment of the Liquid Level sensor with the connector. The range – 0.1-10, default – 0.30.
• Trace gap – The distance (mm) between adjacent trace widths. The range – 0.1-10, default – 0.70.
• Via holes pad – The diameter (mm) of through-hole pads for each sensor between the front and back layer. The range – 0.1-10, default – 0.70.

Foam detection

Enables the foam detection analysis for the selected sensor design.

• PCB type – The PCB technology used for the sensor: Rigid, Flex, Other.
• Core material relative permittivity – The relative permittivity of the PCB core material. The range – 2-10, default – 4.70.
• PCB material – The PCB base material used for the sensor. Available: FR4, FR5, Getek, Rogers4350, Teflon, Polyimide, Polyester, Polyethylene Naphthalate, Liquid Crystal Polymer, Arylon.
• Core material thickness – The thickness (mm) of the PCB core material between the conductive layers. The range – 0.01-5, default – 1.00.
