粘度過程分析儀 VISC-4

Description

All fluids that fulfil the conditions of Newton’s friction law are referred to as Newtonian fluids. Their viscosity is a material constant, which is only dependent on pressure and temperature. The viscosity for incompressible and Newtonian fluids can be derived from the so called Hagen-Poiseuille law. The fluid is assumed to flow under laminar conditions.

Application

The BARTEC BENKE Viscosity Process Analyzer VISC-4 continuously measures the kinematic viscosity of a product via the capillary method. Due to the outstanding performance and sample temperature stability of ± 0.02 K the VISC-4 is the best choice for highly accurate viscosity measurements e.g. lube oil production and fuel oil blending. This high level of accuracy results in cost reduction while improving product quality. The VISC-4 is suitable to handle samples with a viscosity of up to 1000 cSt at measurement temperatures of up to 100 °C.

Special Features

• Direct and continuous measurement of kinematic viscosity therefore direct comparison with laboratory results without any need for conversion
• Integral measurement of the density therefore calculation and display of the dynamic viscosity
• Minimized maintenance requirements due to temperature control and insulating system without oil bath/pumps
• Compliance of the temperature stability (±0.02 K) as defined in standard ASTM D445
• Necessity of Hagenbach correction is eliminated
• Multi-stream capability
• Automatic rinsing and draining option
• Integrated failure diagnosis and self monitoring
• No atmospheric drain required, backpressure at analyzer outlet permitted (depends on application)
• Available communication interfaces:
  - Modbus/RTU, Modbus/TCP (bidirectional)
  - Remote access via Ethernet (VDSL or FOC is)
• Validation report for quality assurance
• Freely programmable digital and analog inputs
