4 Tips for Non Contact Capacitive Liquid Level Sensor

1. Output Configuration: Understand your control system's input type before installation. NPN outputs switch the signal line to 0V (sinking), while PNP outputs switch it to the supply voltage (sourcing).
2. Calibration for Empty State: For best results, always perform the initial setup (entering learning mode) when the pipe is empty to establish the correct baseline reference.
3. Mounting Surface: For consistent performance, ensure the capacitive level sensors is firmly mounted against a clean, dry, and smooth section of the pipe wall without gaps or obstructions.
4. Electrical Protection: Although the capacitive liquid level detection includes reverse polarity and short-circuit protection, always follow proper electrical wiring practices and use a stable power supply within the specified voltage range.
