Product description
The sensor is an integrated online fluorescence dissolved oxygen sensor. It is designed based on the quenching principle of specific substances on excited fluorescence in physics. When the excitation light shines on the fluorescent substance on the surface of the fluorescent membrane head, the fluorescent substance is excited and emits fluorescence. The extinguishing time of the fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent membrane head. The concentration of oxygen molecules can be calculated by detecting the phase difference between the fluorescence and the excitation light and comparing it with the internal calibration curve. The final value is output after temperature and salinity compensation.
Features
◇ No need for electrolyte, no polarization, no need to consume oxygen, and not affected by flow rate.
◇ The fluorescent film head is easy to replace and simple to maintain.
◇ Universal RS485 interface, Modbus/RTU protocol.
◇ Conveniently connected to third-party equipment such as industrial control computers, general controllers, recording instruments, PLC, DCS, etc.
◇ Dual high-impedance differential amplifiers, strong anti-interference and fast response speed.
◇ 3/4 NPT pipe thread is easy to install, convenient for submersible installation or installation in pipes and tanks.
◇ Protection grade IP68.
