IP68 Digital Luminescent Dissolved Oxygen Sensor Low Power Consumption

IP68 digital Luminescent dissolved oxygen sensor low power consumption

The DRFN’s luminescent dissolved oxygen probe is coated with a luminescent material. Blue Light from an LED in the sensor strikes the luminescent chemical on the sensor. The luminescent chemical instantly becomes excited and then as the excited chemical relaxes, it releases red light. The time it takes for the chemical to return to a relaxed state is measured. Oxygen has a dampening effect on this reaction. The higher the oxygen concentration, the less red light is given off by the sensor. The oxygen concentration is proportional to the time it takes for the luminescent material to return to a relaxed state. Then the controller and the luminescent dissolved oxygen sensor calculates the dissolved oxygen concentration in the medium.

Advantage of the Luminescent dissolved oxygen sensor

• No need to be calibrated and can meet the requirements of field work and short-term or long-term operations.
• The probe can complete accurate measurement without consuming oxygen, especially when the oxygen concentration is very low.
• All-in-one package, the luminescent dissolved oxygen sensor can be conveniently used with the online transmitters, DTU, and portable instruments.
• RS485 digital interface, standard Modbus communication protocol, support access to standard industrial control system.
• The protection grade is IP68, and it can work continuously and stably under water for a long time.
• Internal storage of calibration data, support offline calibration, plug and play on site.
