Product Description
The Broadsensor optical DO sensor is coated with a luminescent material. Blue Light from an LED strikes the luminescent chemical on the sensor. The luminescent chemical instantly becomes excited and then as the excited chemical relaxes, it emit red light. The red light is detected by a photo diode. The time it takes for the chemical to return to a relaxed state is measured by referring an independent red led light. Oxygen has a dampening effect on this reaction. The oxygen concentration is proportional to the time it takes for the luminescent material to return to a relax state.
Key Advantages:
Smart sensor retains all calibration in the sensor
Membrane less, no electrodes design
Flow Independent and No oxygen consumption
No warm-up time required
Easy to store, air or water are all ok
User-replaceable sensor cap
Low drift and long life time
All made by Broadsensor, including fluorescent film Support leakage alarm and salinity compensation
Digital output, support RS485 Modbus protocol POM, SS316, TA body are selectable
Note: *Field life and calibration frequency dependent on site conditions.
