0-44000 uS/cm 0-5V output with electrode EC Sensor
EC-TDS transmitter has online one-button calibration, automatic temperature compensation, electrode good or bad during calibration, power failure protection (can make calibration results and preset data not lost due to shutdown or power failure), overcurrent protection, overvoltage Protection, high measurement accuracy, fast response, long service life and so on. The product is small in size, light in weight, easy to install and maintain, and standard industrial signal output (0-5V, 0-10V, 4-20MA, ModbusRTU485) can meet the needs of real-time monitoring of various real-time monitoring devices. The product is convenient to connect with various control devices and display instruments to realize on-line monitoring of EC and TDS status. This product is suitable for: electroplating, fermentation, food processing, sewage treatment, metallurgy, environmental protection and other occasions.
The relationship between the linear analog signal and the corresponding physical quantity:
0-5V output: physical quantity = corresponding range x sensing output voltage / 5.0;
0-10V output: physical quantity = corresponding range x sensing output voltage / 10.0;
4-20mA output: physical quantity = corresponding range x (sensing output current -4.0) / 16.0;
For example: 0-5V output, the range is 4400uS/cm, if the sensor output voltage is 3V, then the corresponding EC value
For: EC=4400uS/cm x sensing output voltage/5.0
=4400uS/cm x 3.0/5.0=2640uS/cm
For example: 4-20mA output, the range is 2000ppm, if the sensor output current is 12mA, then the corresponding TDS value
For: TDS=2000ppm x (sensing output current -4.0)/16.0
=2000ppm x (12.0-4.0)/16.0=1000ppm
