About This Product
■Supports various process connections
DCM-20 is available with various adapters for sensor installation, allowing easy installation in the process. 3-A and EHEDG certifications are supported even when using the provided adapter.
■[Connection method example]
- Direct to process installation with 1.5” or 2.5” ferrules
・Ferrule connection type flow cell from 1” to 4”
・0.5” mini clamp connection type flow cell
・Flange connection type flow cell from 1” to 4” etc.
■Stand-alone method
DCM-20 uses a stand-alone system that does not require external control devices such as a controller or converter. The DCM-20 can be controlled using Modbus TCP (digital communication), allowing you to change settings, perform maintenance, and read measured values on the web browser of your PC or mobile device.
In addition, since it is equipped with two analog outputs at the same time, it is possible to use the analog output for normal reading of measured values, and use digital communication only when changing settings.
■Calibration
All sensors are individually calibrated using traceable refractive index standards for refractive index and temperature to ensure optical performance over the entire measurement range. Configuration is performed according to established procedures and calibration parameters are verified to be valid. The final verification work is done by recording the sensor ID profile associated with each sensor.
The zero point calibration function is used to define the temperature profile and reference baseline for each refractometer. This function is provided for use in circulation lines to check the full functionality of the sensor.
■Refractive index measurement principle
Refractive index measurements are based on Snell's law and the critical angle of total internal reflection. Light passes from the LED through the interface between the optical window and the liquid. Depending on the concentration of the liquid, it is reflected at distinct angles, forming an interfacial image of light and shadow on the digital camera. Information about the element that receives the light is converted into the refractive index unit RIU and Brix value.
