Online refractometer, pulp concentration meter, emulsion concentration sensor

Online refractometer, pulp concentration meter, emulsion concentration sensorProduct Introduction:

Online concentration sensor, consisting of a light source, sapphire refractor, receiver, and signal modulation circuit, with the light source emitting stable optical signalsThe sapphire is in contact with the measured medium, and the corresponding refractive index is generated by the concentration of the measured medium. The optical receiver calculates the refractive index of the collected refractive light source and obtains the corresponding concentration through data algorithms. Since the concentration is affected by temperature, internal temperature calibration is used to reduce the influence of temperature drift.

Maintenance and troubleshooting of online concentration sensors
1. Daily maintenance

• If the instrument becomes dirty, please wipe it with a soft cloth and do not use gasoline, paint thinner, or other cleaning agents to clean the instrument.

2. Regular/scheduled maintenance (can be operated through a cleaning device)

• Wipe the prism of the online refractometer probe clean, add 0.3mL distilled water for testing, and if the value is not equal to 4mA, reset it by pressing the button.

• Online refractometers used for measuring high temperature, corrosive media, or operating under vibration conditions should be calibrated every six months.

• After running the online refractometer for 5 years, an insulation resistance test should be conducted, and the insulation resistance should be above 500M.

3. General troubleshooting

• When there is no signal output from the online refractometer, the first thing to check is whether the cable is broken or short circuited. If so, replace the cable;

• When the online refractometer measurement is abnormal, first measure whether there is a power supply input. If the power supply is normal, please check whether the measurement window of the sensor is open

• The contamination is covered while ensuring good contact between the measurement window and the measured solution; If it is not normal, it is a sensor malfunction. Please return to the factory for repair
