ViscoScope Sensor VA-300

Capteur de viscosité en ligne VA-300

Les capteurs ViscoScope® sont fabriqués en acier inoxydable de première qualité et impressionnent par leur conception intelligente et robuste. Toutes les parties en contact avec le processus sont entièrement soudées. Les pièces mobiles ne s'usent pas et il n'y a pas de fuites qui endommagent l'intérieur du boîtier du capteur. Chaque viscosimètre ViscoScope® est équipé d'une Pt100 intégrée au capteur. Les capteurs VA-300 du ViscoScope permettent une large gamme de variantes et sont donc fabriqués sur commande. Cela garantit une installation optimale dans les usines nouvelles et existantes. Parmi les autres caractéristiques spéciales, citons la capacité CIP / SIP, une surface Ra <0,2 µm, une installation sans espace mort ou une installation en sécurité intrinsèque.

Description du produit Viscosimètre en ligne VA-300

The ViscoScope inline sensor VA-300 requires no maintenance and is designed for accurate, reproducible and reliable measurement of the dynamic viscosity of liquids in real-time. A Pt100 integrated into the probe simultaneously measures the process temperature.
The probe of the ViscoScope® sensor is fully welded to ensure that no moving parts come into contact with the fluid being measured. Electric coils drive the probe at its resonance frequency and stimulate it to an oscillating torsion at a small amplitude. A fast closed-loop PID controller keeps the amplitude constant. Thus the higher the viscosity, the higher the voltage required. This can be used to measure the dynamic viscosity in mPa·s x g/cm3 (η x ρ). The low amplitude at the resonance frequency prevents material fatigue, which could otherwise cause components to move or wear. It also ideal for ensuring that the instrument has a long, reliable and maintenance-free service life.

The ViscoScope® VA-300 sensor is manufactured to order and therefore available in a wide range of versions that optimize installation in new or existing plants. This variety of sensor designs often allows them to be installed with little or no modification to the potential installation site. The sensor can be installed in any position but it should be selected carefully in order to ensure cost-efficient measurements.

• vacuum or high pressure
• very low or high temperatures
• in secure areas or areas with potentially explosive atmospheres
• CIP / SIP compliant or with no dead spaces

In continuous processes, viscosity is monitored permanently. This permits timely adjustment of the system or optimum dosing. Batch applications are often reactive processes, in which the viscosity curve and achieving a specified target viscosity define the optimum point for stopping the process.
However, the degree of homogenization, concentration, molecular weight distribution, coating thickness, lubrication performance and phase separation can also be inferred from the measurement signal – the potential uses are simply limitless. Marimex® has already implemented apparently impossible applications and successfully put them into operation. Most liquids are non-Newtonian so relative viscosity is the relevant measurement in processes. The ViscoScope® system is factory- calibrated using certified Newtonian calibration oils. This multipoint calibration allows the user to obtain reproducible results, e.g. when several systems are used in the same applications, after repair or relocation to a different plant. In order to compare the process viscosity with a known laboratory viscosity, it is necessary to calculate a correlation empirically.
