Digital Sensors
NTU: Nephelometric Sensor
Optical technology for optimized measures

 

 

 

-IR optical sensor with optical fiber
 

-Ranges from 0 to 4000 NTU
 

-Robust and waterproof (IP68)
 

-Very low-power consumption
 

-Digital output Modbus RS-485

 

Application field:

  • Urban wastewater treatment (entrance / exit controls)

  • Sanitation network

  • Industrial effluent treatment

  • Surface water monitoring

  • Drinking water

Optical technology:

The measure principle is based on IR nephelometry at 880 nm (standardized measure of the IR beam at 90). The sensor can be calibrated with a formazine standard solution.

The NTU sensor integrates a low-cost optical technology, with a very few maintenance and no consumables.

 

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 better measures management.

 

Integrated transmitter:
All data concerning calibration, history, users and measures are directly treated within the NTU sensor and transmitted via RS-485 or SDI-12.

 

Physical characteristics:
 

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

 

Technical characteristics:
