Product Description
RS485 Water Quality Sensor Dissolved Oxygen Sensor Fluorescence
RK-3001-O2
Product Introduction1.1 Product overviewThe water quality fluorescent dissolved oxygen sensor is a continuous monitoring instrument probe widely used in dissolved oxygen, saturation, oxygen partial pressure and temperature in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food and tap water.This product adopts fluorescence method, the sensor product has a long life, no maintenance, and excellent performance. The continuous monitoring data can be remotely monitored and recorded through the transmission output and the recorder. It can also be connected to the RS485 interface and can be easily connected to the computer through the MODBUS-RTU protocol. Monitoring and recording.This product is equipped with a waterproof housing to convert the signal of the aqueous solution into a standard 485 signal after digital setting and analysis. The product does not need to be calibrated in one molding process and can be used immediately.1.2 FeaturesThe probe of this product is a fluorescence probe, which uses the principle of fluorescence quenching for measurement. The fluorescence method has been relatively active in recent years.It can overcome the shortcomings of traditional classical measurement methods that cannot be continuously measured online. The fluorescence method does not consume oxygen, is not subject to magnetic field interference, does not consume probes, has high sensitivity, low detection limit, long life, and has a wide range of advantages in sustainable online monitoring. application.1.3 Main parameters1.4 System framework diagram(1)This sensor can be connected and used alone. First, use a 12V DC power supply. The device can be directly connected to a PLC with a 485 interface, and it can be connected to a single-chip computer through a 485 interface chip.The single-chip microcomputer and PLC can be programmed through the modbus protocol specified later to cooperate with the sensor.At the same time, use USB to 485 to connect to the computer, and use the sensor configuration tool provided by our company for configuration and testing.(2)This product can also be used by combining multiple sensors on a single 485 bus. Please follow the "485 bus field wiring rules" (see appendix) when performing 485 bus combination.In theory, one bus can connect more than 16 485 sensors. If you need to connect more 485 sensors, you can use 485 repeaters to expand more 485 devices.The other end is connected to a PLC with a 485 interface, connected to a single-chip microcomputer through a 485 interface chip, or connected to a computer using USB to 485, and configured and tested using the sensor configuration tool provided by our company.Hardware Connection2.1 Inspection before equipment installationPlease check the equipment list before installing the equipment:| name | Quantity |

- Please be careful not to connect the wrong wiring sequence, the wrong wiring will cause the equipment to fail to operate normally or to burn the equipment.
- The sensor should avoid contact with organic solvents, alcohol, paint, oil and high-concentration gases, including silica gel and other adhesives.
- The factory default provides 4.8 meters long wire, customers can extend the wire as needed or wire in order.
There is no yellow line in the line sequence that may be provided in some factory batches. At this time, the gray line is equivalent to replace the yellow line.2.4 Installation instructionsThe probe is a very precise component, and the correct installation method must be used. The wrong installation method will cause the probe to be damaged or irreversibly damaged.The probe adopts pipeline installation, immersion type or flange installation. Please do not put the probe directly into the water, you should choose the probe mounting bracket or the flow cup to fix it.Before installation, be sure to use raw material tape (3/4 thread) to do a waterproof seal to prevent water from entering the probe and causing short circuit of the probe cable.During the water cut, make sure that the probe is immersed in the liquid to be tested or wear a protective cap with a built-in protective liquid. If the temperature is low in winter, if the water is stopped for a long time, an antifreeze device should be added or the room should be returned to add water for storage. Otherwise, the service life will be shortened.485 interface communication protocol3.1 Basic communication parameters| parameter | content |
