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

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

CWT-BL ORP 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) , Over-current protection, over voltage protection, high measurement accuracy, fast response, long life and so on.
  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, Modbus RTU485) can meet the limit of on-site connection to various real-time monitoring equipment.

Application
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:

(-1000~1000mV range)：ORP=ORP output voltage*400-1000；

(-2000~2000mV range)：ORP=ORP output voltage*800-2000；

0 to 10 v output:

(-1000~1000mV range)：ORP=ORP output voltage*200-1000；

(-2000~2000mV range)：ORP=ORP output voltage*400-2000；

4-20 ma output:

(-1000~1000mV range)：ORP=(ORP current-4)*125-1000；

(-2000~2000mV range)：ORP=(ORP current-4)*250-1000；

Due to the ORP electrode in the measurement environment vulnerable to pollution cause electrode signal affected, in order to ensure the ORP 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.
