SPRING TORQUE

DV-I SPRING TORQUE 

Each of our standard Laboratory Viscometers/ Rheometers are supplied with an internal spring used to calculate the viscosity of a material. These springs have different measuring capabilities:
  • LV is for low viscosity materials and can measure the “thinnest” materials. Typical examples include inks, oils, and solvents.
  • RV is for medium viscosity materials than those measured with an LV torque. Typical examples include creams, food, and paints.
  • HA is for higher viscosity materials than those measured with an RV torque. Typical examples include gels, chocolate and epoxies.
  • HB is for even higher viscosity materials than those measured with an HA torque spring. Typical examples include asphalt, caulking compounds, and molasses.
Additional special springs are also available upon request. To learn more about spring ranges and model selection, please call Brookfield Engineering or one of our authorized dealers.

DIGITAL VISCO TESTER
 Type : VT06
 Merk : RION - Japan 





Specification :
 The Rion VT-05/ VT-06 Viscotester provides a unique objective and cost-effective means of directly measuring the viscosity of liquids/ fluids. The viscosity of many substances is of crucial importance yet, up to now, measurement of this quantity has often been achieved through indirect, complicated and/ or expensive methods. Application areas include chemicals, paint, petrochemicals, adhesives and foodstuffs.

 The VT-05 ( for lower viscosity fluids) and VT-06 ( for higher viscosity fluids) consist of a hand-held ( or it can be mounted on a stand) meter with an integral digital display with a rotor that is connected to the rear of the device. With the meter held ( approximately) horizontally, the appropriate rotor is submerged in the fluid to be tested. The meter will then give a direct digital readout of the viscosity of the fluid in millipascal/ decipascal seconds ( the SI unit for Viscosity) .

 The VT-05 can measure up to 300 mPas. The VT-06 can measure up to 4000 dPas.
 Examples of typical viscosity ( at 23° c) :

 Milk - 2.6 mPas;
 Olive Oil - 71 mPas;
 Tomato Ketchup - 43 dPas;
 Toothpaste - 320 dPas.
 A summary of features for the VT-05/ VT-06:
 Direct, objective and repeatable measurement of viscosity;
 Extremely simple operation
 Direct digital readout of viscosity in SI units
 Cost effective;
 Supplied with rotors and other accessories ready for immediate use
 VT-05 Measurement Range up to 300 mPas
 VT-06 Measurement Range up to 4000 dPas
 VT-05 Accuracy ± 5% of measurement range
 VT-06 Accuracy ± 10% or reading - reproducibility ± 5%
 Lightweight ( 260g without batteries)
 Runs on 4 AA cells ( including nickel-hydride rechargeables)

Viskositas adalah suatu cara untuk menyatakan berapa daya tahan dari aliran yang diberikan oleh suatu cairan. Kebanyakan viskometer mengukur kecepatan dari suatu cairan mengalir melalui pipa gelas (gelas kapiler), bila cairan itu mengalir cepat maka berarti viskositas dari cairan itu rendah (misalnya air). Dan bila cairan itu mengalir lambat, maka dikatakan cairan itu viskositas tinggi. Viskositas dapat diukur dengan mengukur laju aliran cairan yang melalui tabung silinder. Cara ini merupakan salah satu cara yang paling mudah dan dapat digunakan baik untuk cairan maupun gas. Menurut poiseulle, jumlah volume cairan yang mengalir melalui pipa per satuan waktu. (Dudgale. 1986)
Viskositas biasanya diterima sebagai “kekentalan” atau penolakan terhadap penuangan. Viskositas menggambarkan penolakan dalam fluid kepada aliran dapat dipikir sebagai cara untuk mengukur gesekan fluid. Prinsip dasar penerapan viskositas digunakan dalama sifat alir zat cair atau rgeologi. Rheologi merupakan ilmu tentang sifat alir suatu zat. Rheologi terlibat dalam pembuatan, pengemasan atau pemakaian, konsistensi, stabilitas dan ketersediaan hayati sediaan. (Moechtar, 1990)
Cairan mempunyai gaya gesek yang lebih besar untuk mengalir daripada gas, hingga cairan mempunyai koefisien viskositas yang lebih besar daripadagas. Viskositas gas bertambah dengan naiknya temperatur, sedang viskositas cairan turun dengan naiknya temperatur. Koefisien viskositas gas pada tekanan tidak terlalu besar, tidak tergantung tekanan, tetapi untuk cairan naik dengan naiknya tekanan (Martin, 1993).
Viskositas merupakan fungsi dari waktu yang artinya dengan bertambahnya waktu viskositas semakin meningkat. Sifat ini penting diketahui sewaktu material cetak dicampur atau saat dimasukkan ke dalam mulut karena viskositas material cetak kosistensi light pada 5 menit setelah pencampuran akan sama dengan kosistensi regular pada 3 menit. (Martin, 1993)
Makin tinggi viskositas maka akan semakin besar tahanannya. Bila viskositas gas meningkat dengan naiknya temperatur, maka viskositas cairan justru menurun jika temperatur dinaikkan. (Martin, 1993).
Pada hukum aliran viskositas Newton menyatakan hubungan antara gaya-gaya mekanika dari suatu aliran viskos. Geseran dalam viskositas (fluida) adlah konstan sehubungan dengan gesekannya. Hubungan tersebut berlaku untuk fluida Newtonian, dimana perbandingan antara tegangan geser (s) dengan kecepatan geser (g) nya konstan. Parameter inilah yang disebut dengan viskositas. Aliran viskositas dapat digambarkan dengan dua buah bidang tersebut. Suatu bidang permukaan bawah yang tetap dibatasi oleh lapisan fluida setebal h, sejajar dengan permukaan atas itu ringan, yang berarti tidak memberikan beban pada lapisan fluida dibawahnya, maka tidak ada gaya tekan yang berkerja pada lapidan fluida. (Dudgale, 1986)
