1% Accuracy Online Conductivity Sensor For Water Quality
This remarkable online conductivity sensor is specifically designed
for water quality assessment with an outstanding accuracy of 1%. It
plays a crucial role in the continuous monitoring of water
conditions.
Equipped with advanced technology, it can precisely measure the
conductivity of water in real - time. This enables it to detect
even the slightest variations in the ionic concentration of the
water. Whether in industrial water systems, municipal water supply
networks, or environmental monitoring projects related to rivers,
lakes, and reservoirs, this sensor is highly reliable.
It has a robust construction that allows it to endure harsh
operating environments, such as exposure to different water
temperatures, pressures, and potential chemical contaminants. Its
online functionality means that it can provide instant data
feedback, allowing for immediate action in case of any abnormal
conductivity levels that may indicate water pollution or other
quality issues.
Electrode type conductivity sensor
1, two electrode type conductivity sensor technology status and
characteristics
Two conductance cell type electrode conductivity sensor is composed
of a pair of electrodes, places, a constant voltage on the
electrode conductivity pool of liquid resistance changes lead to
changes in current measuring electrode, and in accordance with
ohm's law, conductivity instead of resistivity, with the resistance
in the conductance instead of metal, expressing it in electrical
conductivity and the conductance of the liquid conductive ability,
so as to realize the liquid conductivity measurement.
At present, the measurement range of the two electrode type
conductivity sensor is 0~20000 μs /cm, and the different electrode
constants have different ranges: the electrode constant is 0.01
/cm, the measurement range is 0~20 μs /cm;The electrode constant is
0.1 / cm, and the measurement range is 0.1-200μS/cm.The electrode
constant is 1.0 /cm and the measurement range is 10-20 000 μs /cm.
The traditional electrode type conductivity sensor electrode is
composed of a pair of flat electrodes, and the electrode constant
is determined by the opposite area and distance of the
electrode.The electrode structure is simple, the craft is simple,
but the electrode power line was the edge effect and the electrode
area and the distance between electrodes is difficult to determine,
electrode constant cannot be calculated through the size
measurement, need through the standard calibration, one of the most
commonly used standard solution is 0.010 0 mol/L potassium chloride
standard solution.Based on the principle of conductance cell, the
flat electrode is improved, and the cylindrical electrode, point
electrode, line electrode and compound electrode are developed.
Electrode type conductivity sensor has the following
characteristics:
1) Simple structure and convenient manufacturing;2) The subsequent
processing circuit is simple and easy to implement;3) High
measurement accuracy;4) Easy to use.
