LSJ series water leakage sensor

Series leakage and immersion sensor model: B
Before installing and using the sensor, please read this instruction manual carefully for correct use and maintenance.
An overview
The series water leakage and immersion sensor is a probe-type water leakage and immersion transmitter. The resistance of the metal electrode changes. When the external measured liquid contacts the surface of the probe sensor, its resistance value If any changes occur, the amplification process will be carried out. Its structure adopts a fully sealed design to ensure the high precision and reliability of the product. The product has the characteristics of high sensitivity, fast response time, easy use and easy installation.

Four installation methods
Bracket screw fixation
Place the leakage and immersion sensor on the installation surface and detect With the needle pointed in the direction where water is likely to be, the screws are driven directly into the mounting plate.
Five power supply and communication terminal wiring methods
High and low level output electrical wiring instructions:
Red wire: positive power supply
Black wire: negative power supply
Blue wire: electrical Level output positive
White wire: Level output negative
Relay output electrical wiring instructions:
Red wire: Power supply positive
Black wire: Power supply negative
Blue wire white Line: solid state relay output
Six Precautions
Please check whether the packaging is intact, and check whether the transmitter model and specifications are consistent with the product you purchased. If you have any questions, please contact our company as soon as possible.
2. Before use, please confirm whether the power supply output voltage is correct, the positive and negative power supply and the positive and negative wiring methods of the product, ensure that the measured range is within the corresponding range of our company's products, and read the product manual in detail or consult our company.
⒊When installing the sensor transmitter, ensure that the light-receiving surface is clean and placed on the measured surface. Thus better guarantee.
⒋It is strictly prohibited to use external pressure to stamp the light detection sensor to avoid damage to the measuring element under pressure stamping, which may affect the use or cause abnormalities in the sensor or crush the light-shielding film to cause water leakage. Do not use it in high temperature and high pressure environments.
⒌Users are not allowed to disassemble or touch the diaphragm during use to avoid damage to the product.
⒍It is strictly prohibited for the transmitter housing to be scratched, knocked, or banged by knives or other sharp metal connecting wires and objects, which may cause water damage to the transmitter.
