Product Description

Veinasa-RJY06 rs485 aquaculture detector analog smart meter digital fluorescence probe optical dissolved oxygen sensor 

Product Description

 

Veinasa-RJY06 integrated online fluorescence-based dissolved oxygen sensor is designed based on the quenching principle of excited fluorescence by specific substances in physics. When the excited light is irradiated on the fluorescent material on the surface of the fluorescent film head, the fluorescent material will be excited and emit fluorescence. The quenching time of fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent film head. By detecting the phase difference between fluorescence and excitation light and comparing it with the internal calibration curve, the concentration of oxygen molecules can be calculated, and the final value can be output through temperature and salinity compensation.

No need of electrolyte, no polarization;

Do not consume oxygen and not be subject to the flow rate;
With built-in temperature sensor, which can automatically compensate temperature
With built-in salinity compensation, and flexible parameter setting;
Not be subject to the disturbance by chemical substances such as sulfide;
Small drift, quick response, and more accurate measurement;
A long service cycle and a lower cost
Convenient to replace the fluorescent film head and easy to maintain;
RS-485 interface, Modbus/RTU protocol
Low power consumption and anti-interference design.

Installation and Wiring Method

1.Installation

The sensor should be fixed and installed after immersed below the liquid level. During installation and use, attention should be paid not to collide or scrape the surface of the fluorescent film head, and not for underwater precipitate to attach the fluorescent film head. The rubber cover should be removed for use.

 

2.Electrical Connection
The cable is 4-core twisted-pair shielded wire, and the definition of line sequence is as follows:
Red line -- power cord (12~24VDC)
Black line -- ground wire(GND)
Blue line -- 485A
White line -- 485B Check the wiring sequence carefully before power-on to avoid unnecessary losses caused by wiring errors. Wiring instructions: Considering that the cables will be immersed in water (including sea water) or exposed to air for a long time, all wiring points are required to be waterproofed, and the user's cables should have certain corrosion resistance.
