Turbidity probes. 4/20 mA and RS 485 output.

These unique probes have been designed to measure turbidity based on nephelometric method (ISO 7027 – EN 27027). The probes are available for submersible and in-pipe installations.

The measuring system consists of:

• Infrared light source,
• 90 degree scattered light detector,
• Detector of the clean lens status,
• 2-wire 4/20 mA analog output,
• RS 485 digital output
• Nozzle for the autoclean by external pressured air (TU 8325).

Through commands from the Personal Computer hyperterminal, the serial interface allows the measuring and check signals transmission, the scale selection, the analog or digital operating mode selection, the zero and sensitivity calibration.

Thanks to its 4/20 mA isolated output, the probe can be directly connected to a PLC or data logger, and configured in NTU, g/l, % or other.

The probe can be connected to B&C Electronics controller BC 7335, BC 7635, BC 7635.010, BC 7687 or BC 6587, which provide the power, the measuring readout, 2 set-points, the alarm relay and the holding function for an external cleaning cycle.

The most common applications of this probe include: water quality monitoring, municipal and industrial water treatment and aquaculture
