Installation method of fluorescent dissolved oxygen sensor

The equipment adopts an immersion installation method, which is a fixed installation immersed below the liquid surface. Avoid bumping and scratching the surface of the fluorescent membrane head during installation and use. The fluorescent membrane head should be protected from underwater sediments. The rubber protective cover should be removed during use. The sensor thread can be customized based on the thread of the waterproof pipe.

The basic principle of fluorescent dissolved oxygen sensor

The sensor mainly uses the principle of fluorescence quenching. Blue light irradiates the fluorescent material to excite the fluorescent material and emit red light. Since oxygen molecules can take away energy (quenching effect), the time and intensity of the red light excitation are inversely proportional to the concentration of oxygen molecules. By measuring the phase difference between the excitation red light and the reference light and comparing it with the internal calibration value, the concentration of oxygen molecules can be calculated.

Comparative advantages of fluorescent dissolved oxygen sensors:

1. No oxygen consumption

This type of equipment does not consume oxygen, has no flow and stirring requirements, and can better meet the needs of oxygen measurement.

2. High-precision probe

The device has higher resolution and measurement accuracy, and the measurement is fast and sensitive.

3. Wide-voltage power supply

The equipment uses a wide voltage power supply, can use DC6~24V, and can adapt to various DC power supplies on site.

4. RS485 communication interface

The equipment uses MODBUS RTU communication protocol, which can be easily connected to a computer for monitoring and communication.

5. Temperature compensation

The equipment has a built-in temperature transmitter with an automatic temperature compensation function, which can reduce measurement errors and improve accuracy.

6. Long-term maintenance-free

The equipment does not need to replace the diaphragm and electrolyte, is maintenance-free, and has a longer service life.

7. High-protection shell

Conventional freshwater aquaculture can use SS316 shell.

For saltwater or seawater aquaculture, a highly protective and corrosion-resistant shell is used, with a waterproof grade of IP68, which is more stable; all sensors use titanium alloy shells, which are resistant to salt and alkali corrosion for a long time.

During the breeding process, due to climate change or water quality deterioration, the dissolved oxygen in the water is low. At this time, the breeders need to supplement oxygen. In the past, breeding was based on experience. The staff needed to patrol the pond three times a day. When to add oxygen? How much? It can only be done by “estimation”. If the adjustment is inaccurate, it will affect the growth of aquatic animals. Nowadays, the aquaculture industry is in the stage of transformation and upgrading, and the use of scientific and technological forces for intelligent breeding is becoming a mainstream trend.

Shenzhen ODS Technology Co., Ltd’s dissolved oxygen sensor uses the principle of fluorescence measurement to monitor the dissolved oxygen concentration signal of each breeding pond in real-time, which is scientific, accurate, and economical. It saves time and effort and facilitates the breeders to understand the pond situation in real-time and take corresponding measures in time to achieve the effect of intelligent breeding. It can be widely used in water treatment, aquaculture, biological response, environmental monitoring, laboratory, medical, and many other fields.

The application of fluorescent dissolved oxygen sensors can help farmers scientifically “do a good job” of dissolved oxygen, ensure a good water quality environment, and take an important step in “raising water”, avoiding the traditional empirical theory of regulating water quality, and achieving efficient management and increased production. The value-added effect is more in line with the general trend of intelligent transformation of aquaculture.
