Digital Sensors
ODOT: Optical Dissolved Oxygen Temperature
Optical technology for optimized measures

Optical Technology: No membrane nor electrolyte
No drift: No calibration
Digital output: Modbus RS-485 or SDI-12
Stainless steel body: Robust

Application: field:

• Urban wastewater treatment (network control, entrance, aeration pool for the nitrification / denitrification process)

• Industrial effluent treatment

• Surface water monitoring

• Fish farming

• Drinking water

Optical Technology:

The ODOT sensor with an integrated temperature sensor is based on optical measure: a diode emitting blue light is directed to an oxygen light-sensitive layer. The sensitive material reacts emitting a red light (luminescence) which emission depends on oxygen concentration
 

This innovative method assures reliable, precise and driftless measures, calibration is no longer necessary. Without consumable, calibration and maintenance, the ODOT sensor leads to a rapid return on investment. Only the DOdisk is to be changed once every two years.
Oxygen-free consumption, the ODOT sensor is adapted to any fields, including those with very low water circulation.

Digital communication:

The PONSEL sensor can be connected to any types of transmitters, display units, controllers or data loggers with Modbus RS-485 or SDI-12 inputs. Thanks to the sensor indexation, over 200 sensors can be connected on a data logger.

Disruption-resistant: Integrated preamplification and digital treatment of signals.
The optical sensor saves its calibration data for a better measures management.

Integrated transmitter:

All data concerning calibration, history, users and measures are directly treated within ODOT sensor and transmitted via RS-485 or SDI-12.

Physical characteristics:

Compact, robust and light, the stainless steel sensor allows a handheld or fixed unit application.
