Online refractometer

Imported 614 type online refractometer

● Application areas:
Pulp and paper industry, sugar industry, chemical industry, food and beverage industry, milk industry (dairy industry), other industries, etc;

● General characteristics:
1) It can measure and display parameters such as concentration, refractive index Brix, refractive index,% solids, etc;
2) Computer control, two-part optical/electronic measurement system;
3) Single sensor or dual single sensor mode can be used;
4) Adopting the "critical angle" measurement technique, which measures the refractive index at the interface;
5) Adopting an infrared detection system can provide good resolution and avoid drift;
6) On the interface, light undergoes reflection and refraction, and the angle is related to the refractive index (optical density) of the process liquid. This technology can test the solubility of solids during the flow process;
7) The test head, online or inserted probe, is fixed in position to ensure that the prism (detection interface) is in direct contact with the process fluid. Wet prism surfaces can provide physical properties for testing critical angles. The inclusion of air, viscosity, suspended particles and crystals, and color (opaque or transparent) will not affect the precise measurement of the instrument;

● Software usage:
1) Advanced, automated computer processing software control systems can simplify the system. All information can be clearly displayed on the LCD screen. Calibration and diagnostic work can be easily performed through the interface and 5 touch keys. Users can choose to display the main interface or a continuous trend chart, both of which provide parameters such as measurement and current temperature;
2) The instrument can change the calibration value through a remote control box. The display panel of the control box can provide parameter information such as measurement and current temperature. Can be placed 3 km away and communicate information through 2 RS-485 interfaces. Remote control can return to zero;

● Technical features:

2) Concentration,% solids, refractive index Brix0-100%;
3) Accuracy: ± 0.5% of testing range, ± 0.0% of internal computer correction;
4) Stability/Drift: No measured drift;
5) Connection cable length: maximum length 500m;
6) Interface: RS-232; Information communication: RS-485; A drive: can hold floppy disks;
7) Sensing window (prism): sapphire;
8) Process signal output: 4-20 mA, 0-10 VDC;
9) Process sample temperature range: -25 ° C to 150 ° C, automatic temperature compensation;
10) Process sample pressure range: up to 1000 PSIG (68 Bar);
11) 2 types of alarms: exceeding the testing range or system failure;
12) Process sample temperature signal output: 0-10 VDC;
13) Power supply: 230V/50Hz, less than 25W.
