Utilizing UA20B – Water Leak Sensor

Thank you for purchasing DEKIST UA20-B.

UA20-B is designed to support 12VDC power output terminal and 4-20mA 1 channel. Therefore, the leak detection function can be conveniently used by configuring the leak sensor and the resistor in parallel.

2. 1.5 kΩresistance

3. UA20B

1. Connecting the UA20B water leak sensor

1. Check the channels on the back of the UA20-B. With the USB port facing up, the terminal block of 4 consists of a 12VDV power output and a 4-20mA signal input on the left.

2. Setting up Radionode UA Calibration

1. The input mode is changed to 0~20mA. The factory default for input mode is 4-20mA.
2. If there is no leakage: The minimum value of 4mA is output.

3. When moisture is detected in the sensor part: The amount of water and the numerical value are directly proportional. (Max. 20mA)
