Rs485 PH Sensor With Split Wire For Industry Sewage Or Drinking Water

Digital pH sensor DPH790 with separate cable technology combines the advantages of digital signal processing and separate cables, providing higher measurement accuracy and reliability.

Digital Signal Processing: Digital pH sensors use a digital signal output instead of the traditional analog output. Digital signal processing provides higher immunity to interference, which can reduce the influence of external interference on the signal, thereby improving the stability and accuracy of the measurement.

Built-in temperature compensation: Digital pH sensors are usually equipped with a built-in temperature sensor, which can monitor the ambient temperature in real time. In this way, the sensor can be automatically temperature compensated to ensure the accuracy of pH measurement results at different temperatures.

Digital communication interface: Digital pH sensors usually adopt modern digital communication interface RS485, Modbus, so that it can be directly connected with computer, PLC or other digital control systems. In this way, remote monitoring and control can be realized, while errors in the data transmission process are reduced.

Advantage:
Improve measurement accuracy: Digital signal processing and built-in temperature compensation make the measurement results of digital pH sensors more accurate and reliable. At the same time, the digital communication interface can reduce the interference in the signal transmission process and further improve the measurement accuracy.

Strong anti-interference: digital signals are more anti-interference than analog signals. Through the digital communication interface, the digital pH sensor can work in an industrial environment with severe electromagnetic interference and maintain stable measurement performance.

Flexibility and scalability: Digital pH sensors can often be used with other digital sensors and integrated into existing automation systems through communication interfaces. This flexibility and scalability make the system design more convenient, and can be customized according to the needs of the configuration.

Easy installation and maintenance: The split cable design makes the installation and maintenance of the digital pH sensor easier. The sensor section can be replaced or maintained more easily without affecting the operation of the overall system.

In general, digital pH sensor with separate cable technology combines the advantages of digital signal processing, built-in temperature compensation and separate cable, providing higher accuracy, reliability and flexibility for pH measurement, suitable for various industrial applications.

FAQ
1. What is the measurement principle of this pH electrode?
A: The pH value potentiometric method uses the potential difference of glass electrodes for pH measurement.

2. How to judge the pH of the solution?
A: If the internal hydrogen ion concentration of the pH glass bulb is lower than the outside, the measured solution is recorded as acidic and the pH value is lower than 7; if the two are the same, the solution is neutral and the pH value is equal to 7; if the internal hydrogen ion concentration is higher than externally, the measured solution is alkaline and the pH value is higher than 7.

3. How often must the pH sensor be calibrated?
A: Depends on the type of sample:
Dirty samples and non-aqueous samples require more frequent calibration.
Depends on the required accuracy:
For very accurate measurements, at least daily calibration is required.
Depends on the quality of the electrode:
Old electrodes require more frequent calibration.
