The TBS 2100E series Viscometers are high performance, low
maintenance, instruments incorporating the features of both the TBS 500
and SSTBS models, with the added benefit of having Full-Automation
capabilities. The 2100E series models preserve the same high
level of quality, precision and reliability previous TBS models have
enjoyed over the nearly three decades of production.
There are a
number of unique advantages that have long been associated with the
TBS. It provides constant temperature control, ease of operation, quick
?chase-flush? sample exchange, simple determination of shear rate,
etc. The 2100E series continues the tradition of offering the
best of modern technology and incorporates several value-added features
that set new standards for high temperature, high shear (HTHS)
viscometry of new and used
oils. For research, the most important of these is the ability to
change shear rates on a given oil by adjusting the rotor speed over a
broad 12-step range. For routine analysis and maintenance, the most
important features are the elimination of most maintenance checks and a
smaller footprint.
The TBS 2100E motor is capable of
running at 12 different speeds (just as the previous model SSTBS). This
gives the operator the ability to change the shear rate by simple
adjustment of the motor speed dial ? since the speed is proportional to shear rate. The unit is capable of achieving shear rates ranging from 50,000 sec?1 to over 7,000,000 sec-1.
The variable speed DC motor makes it invulnerable to changes in
frequency and is smaller and more powerful than the TBS 500 motor --
allowing oils with viscosities up to 30 cP to be tested (depending on
temperature and shear rate). Additionally, the motor wires are fixed
thus eliminating the need for splaying, or separating.
The
incorporation of a new style In-Line Transducer permitted a smaller,
more basic, redesign of the motor plate and eliminated the need for ball
bearings. Consequently, general maintenance requirements are kept to a
minimum.
The footprint of the 2100E (without Console
Box) is now only 7? x 12?. Although the basic layout is the same as
previous models, the overall size of the unit has been reduced through
redesign resulting in a 2/3 reduction in bench space.
As with the TBS 500, the TBS 2100E unit
is capable of being equipped with a ?Windows? based Semi-Automation
Package for automatic injection of up to 56 oil samples. With the new
TBS 2100E-F model, a
Full-Automation Package is available for computer controlled instrument
calibration, sample injection and data output. Please see the TBS 2100E series brochure and specification sheet for more details.
