Intelligent conductivity sensor
1. Product introduction
The intelligent conductivity sensor is a conductivity intelligent water quality sensor that uses RS485 communication interface and standard Modbus protocol. It is suitable for the measurement of low,medium and high range conductivity. The electrode constant is from 0.1 to 10cm-1. The electrode materials include graphite,platinum and stainless steel. It can measure conductivity,TDS and salinity. Corrosion-resistant shell,built-in PT1000 temperature sensor and compensation algorithm,suitable for various harsh working environments. The sensor has the advantages of good accuracy,good linearity,and stable cell constant. Widely used in surface water monitoring,industrial wastewater and municipal sewage monitoring,water treatment industry,boiler return water monitoring,deionization process monitoring,reverse osmosis monitoring,seawater,salt water,aquaculture water monitoring,etc.
2. Working principle
Conductivity is a measure of the ability of a medium to conduct electricity. The unit is usually expressed in μS/cm or mS/cm. The conductivity of pure water is less than 0.05μS/cm at room temperature,the conductivity of natural water or surface water is 100-1000μS/cm,and the conductivity of acid-base solutions can reach 1000mS/cm. . Put two coaxially placed electrodes in the sample solution,add a sine wave voltage between the electrodes,and measure the current value. Calculate the conductance value G or resistance value R based on Ohm's law. Determine the conductance through the electrode constant K related to the structure. Rate.

5. Dimensions chart
*Note: The sensor connector is an M16-5-core waterproof male connector.
6. Sensor installation
The sensor should be installed and tested at least 2cm away from the bottom and side walls of the container.
7. Electrical connection
The sensor cable is a 4-core twisted pair shielded wire,and the wire sequence is defined as follows:
lred line—Power cord (12~24VDC)
lblack line—Ground wire (GND)
lblue line—485A
lwhite line—485B
The wiring sequence should be carefully checked before powering on to avoid unnecessary losses caused by wiring errors.
Wiring instructions: Considering that cables are immersed in water (inc seawater) or exposed to the air for a time,all wiring locations are required to be waterproofed,and user cables should have certain anti-corrosion capabilities.
8. Application Market
Widely used in surface water monitoring,industrial wastewater and municipal sewage monitoring,water treatment industry,boiler return water monitoring,deionization process monitoring,Reverse osmosis monitoring,seawater,salt water,aquaculture water monitoring,etc.
