RK500-04 Dissolved Oxygen Sensor (Output signal: 4-20mA and RS485)
RK500-04 Dissolved Oxygen (DO) Sensor is based on the principle of quenching excited fluorescence by specific substances in physics.
◆ Simple operation and high reliability.
◆ No external module, a whole design.
◆ Long service life, maintenance-free.
◆ Dissolved oxygen and temperature measurement at the same time
◆ Output signal: 4-20mA and RS485 at the same time.
◆ No requirement for liquid velocity.
◆ Not affected by ions.
When the excited light is irradiated on the fluorescent substance on the surface of the fluorescent film head, the fluorescent substance is excited and emits fluorescence.
The fluorescence extinction time is affected by the concentration of oxygen molecules on the surface of the fluorescent film head. So the oxygen molecule concentration can be calculated by detecting the fluorescence extinction time.
By using green light and unique phase technology, the membrane lifespan attenuation is reduced, and it can be used for more than 2 years without the need for calibration.
DO sensor can be widely used in chemical fertilizer, metallurgy, environmental protection water treatment, engineering, pharmaceutical, biochemical, food, aquaculture and water such as continuous monitoring ofdisso lved oxygen in the solution.
