Abstract

The invention discloses an optical dissolved oxygen sensor with automatic salinity compensation and a manufacturing method thereof. The sensor comprises a sensor probe shell, an optical fiber or an optical fiber bundle arranged in the sensor probe shell, a conductivity electrode arranged in the optical fiber or the optical fiber bundle and a PCB module arranged at the tail end of the sensor probeshell. A photosensitive film array is arranged between the optical fiber or optical fiber bundle and the senor probe shell, and a window corresponding to the photosensitive film is formed in the sensor probe; the conductivity electrode comprises a conductivity electrode shell and a conductivity electrode piece arranged in the conductivity electrode; the PCB module comprises a PCB, an LED light source and a photoelectric diode, the LED light source comprises an excitation light source and a reference light source, and the photoelectric diode is electrically connected to the PCB; the conductivity electrode piece is connected to the PCB through a wire. The sensor measures conductivity in water and has the function of measuring the temperature and the content of dissoluble total solids, so that the sensor has the characteristics of being high in stability, quick in response time and capable of transmitting remotely.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to an optical dissolved oxygen sensor with automatic salinity compensation based on optical fiber technology and a manufacturing method thereof. Background technique [0002] Dissolved oxygen refers to the molecular oxygen dissolved in water, which is a key indicator to measure the quality of water body. Therefore, detecting and controlling the concentration of dissolved oxygen in water is the key link to realize the optimization of water quality. As my country deepens the reform of the environmental monitoring system and mechanism, plans the needs of the ecological environment monitoring system in the new era, and optimizes and adjusts the national industrial structure, the second-generation electrochemical measurement technology used in China is due to its limited measurement accuracy, cumbersome operation, and frequent maintenance requirements. The shortcomings can no ...
