Water PH Temperature Transmitter Detection Sensor Module Voltage 0-5V 0-10V 4-20mA RS485 Output PH sensor PH electrode BNC

CWT-BL PH temperature transmitter adopt double high-impedance three-electrode system, with online one-key calibration, real-time temperature compensation, electrode loose alarm, electrode good or bad alarm during calibration, and power-off protection (the calibration result and preset data will not be lost due to shut down or power failure) , Overcurrent protection, overvoltage protection, high measurement accuracy, fast response, long life and so on.
   The user-friendly online one-key calibration function is convenient for users to calibrate and correct the electrode regularly. Combined with temperature compensation and power-off protection functions, it can effectively complete the conversion, processing, and other processes of measurement data.

  The product is small in size, light in weight, easy to install and maintain, and the standard industrial signal output (0-5V, 0-10V, 4-20MA, ModbusRTU485) can meet the limit of on-site connection to various real-time monitoring equipment.


This product is suitable for: electroplating, yeast, food processing, sewage treatment, metallurgy, environmental protection and other occasions.

The linear relation between analog signals and the corresponding physical value:

0 to 5 v output: PH=PH output voltage*2.8, temperature=temperature output voltage*20.0-20.0;

0 to 10 v output: PH=PH output voltage*1.4, temperature=temperature output voltage*10.0-20.0;
4-20 ma output: PH= (PH output current-4.0)*0.875, temperature=(temperature output current-4.0)*6.25-20.0;

Due to the PH electrode in the measurement environment vulnerable to pollution cause electrode signal affected, in order to ensure the PH sensor can normally use for a long time, usually need to make a correction on a regular basis through the calibration of transducer (once a month).Depending on the water samples of specific calibration cycle.
