SV-10 Sine-wave Vibro Viscometer

Newly developed Tuning-fork Vibration Method promises you high accuracy and wide measurement range without replacing sensor plates!! Sine-wave Vibro Viscometer SV-10 measures viscosity by detecting the driving electric current necessary to resonate the two sensor plates at constant frequency of 30Hz and amplitude of less than 1mm

High Measurement Accuracy
Tuning-fork Vibration Method turns into reality for excellent repeatability of 1% of reading for viscosity measurement by Sine-wave Vibro Viscometer SV-10.
Low Viscosity Measurement And Wide Measurement Range
 Low viscosity of 0.3 mPa·s ( cP ) to high viscosity of 10,000 mPa·s ( cP ) sample fluid can be measured without changing the sensor plates.
Real-Time Measurement
 The sensor plate for the SV-10 is of a thin and small size, in area and in mass, making it is less influenced by the temperature change of the sample fluid and as a result the viscosity measurement tracks the change of viscosity of sample fluid.
Temperature Measurement
It is very important to measure the temperature of the fluid correctly because the viscosity is very much dependent upon the temperature of the fluid. SV-10 can detect accurate temperature immediately because the fluid and the detection unit (sensor plates) with small surface area/thermal capacity reach the thermal equilibrium in only a few seconds.
Continuous measurement
SV-10, Tuning-fork Vibration Method does not cause damage to the sample fluid and allows measurement of cloud point of samples such as surface active agents and of surface/interface changes such as wettability because of its excellent feature for wide measurement range without the need to replace the sensor plates.
 Non-Newtonian Sample Viscosity Measurement
Thin sensor plates allow little deformation of sample texture and thus enable measurement of stable viscosity values.
 Foaming Sample Measurement
Low drive frequency of 30Hz allows measurement of foaming samples without breaking minute foams and with less influence scattering larger foams. Even the viscosity of flowing samples can be measured, including liquid in turbulent flow, which enables field management with identical data used at the laboratories.
 Separated type model
SV-10 is composed of the Display Unit and Main Unit offering excellent placement flexibility.
 Vacuum Fluorescent Display
You can avoid unnecessary reading errors with easy-to-read, large, clear display: 13mm height for viscosity measurement and 11mm height for temperature measurement.
 Small Sample Size
Standard sample cup requires the sample fluid of just more than 35 ml so you do not need to waste too much sample fluid.
 Easy Cleaning
Due to the simple structure, the SV-10's sensor plates, temperature sensor and the protector made of stainless steel (SUS 304) can be easily and quickly cleaned.
 Sol and Gel Measurement
Sol and Gel sample fluid like a starch can be measured during the change of material characteristic.
 Standard RS-232C Interface
The RS-232C comes standard for your PC or Printer connectivity and the connection cable (25 pin – 9 pin) is also standard accessory for your convenience.
 

Measurement Principle for SV-10
The SV-10 has of 2 thin sensor plates that are driven with electromagnetic force at the same frequency by vibrating at constant sine-wave vibration in reverse phase like a tuning- fork. The electromagnetic drive controls the vibration of the sensor plates to keep in constant amplitude. The driving electric current, which is exciting force, will be detected as the magnitude of viscidity produced between the sensor plates and the sample fluid. Tuning-fork Vibration Method does not cause damage to the sample fluid and allows measurement of cloud point of samples such as surface active agents and of surface/interface changes such as wettability because of its excellent feature for wide measurement range without the need to replace the sensor plates.

WinCT-Viscosity
WinCT-Viscosity (RsVisco) is software to import the measurements of viscosity and temperature from SV-10 to a PC automatically and display the measurement result by graph on real-time basis. The CD-ROM of WinCT-Viscometer is equipped as a standard accessory of Viscometer SV Series. The scaling function and the logarithm display is selectable in the function. Saving the measurement data by “CSV” file and opening it with the WinCT-Viscosity is very easy and convenient for your analysis of your sample fluid viscosity
Via RS232C, this software enables A&D’s Sine-wave Vibro Viscometer SV Series to display the progress of measurement in real time on a PC or easily transmit the measured results (data) to save or analyze. RsVisco: Graphing software to create graphs of the measured results and the progress of viscosity measurement.
1. Creates the real-time graph of data received from A&D’s Sine-wave Vibro Viscometer SV Series via RS-232C. Progress of change in viscosity during measurement can be monitored in a graph. Temperature data also can be simultaneously displayed, and the graph of temperature and viscosity can be monitored in real time.
2. The following three types of graphs are provided to choose from;
Viscosity (Y axis) – Time (X axis)
Viscosity/Temperature (Y axis) – Time (X axis)
Viscosity (Y axis) – Temperature (X axis)
3. Graphs can be overlaid in repeating measurements. (in 10 colors)
4. Measured data can be saved in a CSV format file.
5. Displayed graph can be printed with a printer via a PC.
