Digital Conductivity Sensor Salinity With 4 Electrodes For Wastewater Treatment
The digital conductivity sensor C4E is designed with smart digital technology for optimized measures. The conductivity probe can be widely used in urban wastewater treatment, industrial effluent treatment, surface water monitoring, seawater, and drinking water.
Introduction Of The Digital Conductivity Sensor
The sensor works with 4 electrodes: an alternating current of constant-voltage is established between a primary pair of electrodes in graphite. The secondary electrodes in platinum allow of regulating the voltage to imposed to the primary’s electrodes to reflect the fouling. The voltage measured between the primary’s electrodes is in the function of the resistance of place and so, of the conductivity.
Advantages of The Digital Conductivity Sensor
"plug and play" system without re-calibration
Universal Modbus RS485 protocol
Robust and Watertight
