News: DC 8-24V Capacitive Liquid Level Sensor Non-contact Water Level Detection Sensor NPN PNP Touch Switch for Water Tower Fish Tank LCPBA01

LCPBA01 is a non-contact liquid level sensor developed and produced by eletechsup. It can detect the height of the liquid level through the outer wall of the container.

Working current: 8-12MA (12V);

Output mode: NPN or PNP;

Output current: ≤100mA;

Response time: 500ms;

Working temperature: -20-75℃;

Sensing thickness: ≤5mm;

Lead length: 200MM

Lead interface: XH2.54 3P

Size: 59 X 26 X13MM;

Weight: 12g.

 

How to use:

1 The product has been tested and calibrated before delivery. After power on, the light will turn on when it is pressed against the outer wall of a container with water. The light will turn off when it is pressed against the outside of a container without water. (Please see the first 10 seconds of the video of ''LCPBA01 DEMO 1'')

 

2 If there is no light, you can re-adapt: ​​please open the shell, press against the outer wall of the container with water, short press the KEY button, the LED light will flash 4 times and then turn on, and the adaptation is complete. (Please see the video after 10 seconds of ''LCPBA01 DEMO 1'')

 

3 If the second step cannot be adapted, please recalibrate the sensitivity: (Please see the video of ''LCPBA01 DEMO 2'')

1 Fill the container with some water.

2 Press against the outer wall of the container (where there is no water), press and hold the button until the LED light flashes quickly and then turns off.

3 Press against the outer wall of the container (where there is water), short press the button, the LED light will flash 4 times and then turn on.





Abnormal handling:

Q1: After opening the shell and pressing the KEY button, the light does not flash.

A1 Please check whether it is powered by a DC 8-24V power supply, and check whether the positive and negative poles of the power supply are reversed.

 

Q2: After pressing the KEY button, the light flashes, but it is not always on.

A2: 1 Please press the container with water. 2 Please check whether the PCB board is close to the shell. 3 The container may be too thick, please replace the container.

 

Q3: The light will turn on when you touch the back of the shell or the desktop with your hand.

A3: This is normal. Because this sensor is equivalent to a capacitive touch switch.

 

Q4: The port level change of the NPN version cannot be measured with a multimeter.

A4: This is normal. When NPN has output, it is low level, and when there is no output, it is suspended.

 

Q5: The sensitivity of multiple boards is inconsistent.

A6:

1 Please recalibrate the sensitivity. How to calibrate sensitivity:

1 Fill the container with some water.

2 Press the container against the outer wall (where there is no water). Long press the button until the LED light flashes quickly and then turns off.

3 Press the container against the outer wall (where there is water). Short press the button, and the LED light flashes 4 times and then turns on.



2 Please press the PCB board and the shell again. You can use glue if necessary.
