Online fluorescence dissolved oxygen sensor
1. Applications
The fluorescence dissolved oxygen sensor uses a new generation of fluorescence lifetime technology. Kacise independently develops high performance fluorescent materials. No anaerobic consumption, no flow restrictions, no electricity required. The solution requires no maintenance and calibration, no hydrogen sulphide, and excellent stability. Built-in temperature sensor and automatic temperature compensation. The RS485 output is suitable for networks without a controller.
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

Installation and electrical connection
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.
Cable specification: Considering that the cable is immersed in water (including sea water) for a long time or exposed to the air, the cable has certain corrosion resistance. The outer diameter of the cable is Φ6 mm and all interfaces are waterproof.
