LH-DE21 Digital Conductivity Intelligent Sensor
This sensor is used for conductivity of water measuring. The measuring principle is to place two electrodes with a fixed area and distance in the liquid to be measured, apply a constant voltage at both ends of the electrode plate (generally a sine wave voltage to avoid polarization effect), under the action of the electric field, ions in solution will move in a certain direction. Measure the current passing between the plates, and calculate to obtain the conductivity of the liquid to be measured.
• Coaxial structure design, excellent resistance to changes in electrode constants, mechanical damage or temperature effects.
• 516L liquid connection material, better improve the measurement accuracy.
• Built in temperature sensor with automatic water temperature compensation function.
• Supports MODBUS / RS485 output.
It is suitable for realtime conductivity monitoring in sewage treatment, aquaculture, environmental monitoring, waterworks and other industries.
