Electrochemical oxygen sensor

RS-485

Online fluorescence dissolved oxygen sensor Introduction KWS630 fluorescent dissolved oxygen sensor adopts fluorescence method to measure dissolved oxygen in water. The film at the top of the sensor is covered with a layer of fluorescent material. When the light emitted by the light-emitting diode is in the fluorescent material, the fluorescent material will emit fluorescence when it returns to the ground state from the stressed state. The concentration of dissolved oxygen can be measured by measuring the duration of the fluorescence. Built-in temperature sensor automatically compensates dissolved oxygen values according to temperature changes. Features No electrolyte required, no polarization No need to consume oxygen, no flow rate Built-in temperature sensor Automatic temperature compensation Free from chemical interferences such as sulfides Small drift, fast response, more accurate measurement Maintenance free, longer cycle life and lower cost of ownership Fluor cap replacement is simple RS-485 interface, Modbus-RTU protocol 1. The temperature sensing part of the installation should be immersed below the liquid level to avoid collision with the surface of the membrane head. The membrane head portion should be protected from deposits. 2. Electrical connection Red line - power cord (12 ~ 24V) Black line - ground (GND) Blue line - 485A White line - 485B Bare wire - shield After wiring is completed, it should be carefully checked to avoid incorrect connections before powering up.
