HK7

Product catalog summary

Introduction: The document describes the HK7 Spectrometer by Harrer & Kassen GmbH, designed for continuous in-line ICUMSA measurement of sugar. It highlights the use of a visible light detector with no moving parts, ensuring stability and low maintenance.

Specifications: The HK7 uses LED illumination (390nm to 720nm) to measure sugar's whiteness/ICUMSA value. It outputs data via a 4-20mA signal or serial interface. The modular design allows installation in hard-to-reach areas. The sensor operates effectively with distance variations of ±25mm, and a dust-free environment is recommended for optimal results.

Measurement Design: Sugar moves on a conveyor belt under the sensor, which is positioned 150mm-200mm above. The system uses compressed air to keep the sensor dust-free.

Advantages: Unlike competitors, the HK7 uses LED instead of Xenon-Flashlight, offering improved measurement stability and a minimum 10-year LED lifespan. It provides excellent ICUMSA and TYPA tracking compared to lab results.

Calibration Software: The system uses special LEDs for irradiation, with diffuse reflection data transmitted via fiber optics to the spectrometer. The spectrometer splits spectra into 256 points, allowing noise-free wavelength selection.

Technical Data: The evaluation unit is housed in stainless steel, with dimensions of 400 x 499 x 212 mm and a weight of 20 kg. It features IP66/NEMA 4 protection, operates at -20°C to +40°C, and includes various interfaces and outputs. The sensor is housed in aluminum die casting, with dimensions of 280 x 230 x 110 mm and a weight of 4 kg.

Scope of Supply: The HK7 package includes the sensor, evaluation unit, calibration button, and software, with user training provided at commissioning.

Directives: The HK7 complies with CE, EMC, low-voltage, and RoHS directives, ensuring safety and environmental standards.

Customer Benefits: The HK7 offers real-time measurement, continuous production monitoring, consistent quality, early fault detection, multilingual menus, and secure data handling. It maintains measurement accuracy despite distance variations and eliminates drift from lamp aging.

Description: Continuous, controlled LED illumination (wavelength of 390nm to 720nm) to detect the degree of whiteness/ ICUMSA value of sugar. The HK7 calculates the ICUMSA value. The calculated ICUMSA value is available as 4- 20mA signal and/ or via serial interface. Through the modular construction (Sensor and evaluation unit are separate), the sensor can be installed at a difficult accessible places. This ensure the easy handling. With the easy to use calibration function (calibration button), our customer can take spectra's for the calibration with the calibration button at the measurement...
