Transducers protect customer's investment.
The AR Series of rheometers from TA Instruments
utilises a cable extension position transducer from
Variohm-EuroSensor to prevent damage to any
accessories fitted to the rheometer when in use.
This damage could occur if the vertical travel of the motor wasn't
monitored. The Z115 unit supplied by Variohm-Eurosensor
continually tracks the absolute head position.
TA Instrument's units are used to study the flow and deformation
of materials. The material samples are subjected to varying
forces, temperature and pressures. These varying conditions
are applied by means of special heads fitted to the rheometer.
The heads vary in size and this is why TA Instruments needed
to have a means of knowing where the heads are. The Z115
uses a precision potentiometer operated by a cable and drum
to continuously monitor the head position. Because the Z115
is an absolute device it will give an accurate position even if
the power supply is interrupted.
TA Instruments claim that their AR-G2 is the first commercial
rheometer utilising a magnetic thrust bearing technology, a
feature which allows for ultra-low nano-torque control. The
AR-G2 is packed with other features such as drag cup motor
technology, image capture software and a high temperature
oven camera.
AT Instrument's spokesman Peter Foster said that the Z115
from Variohm-Eurosensor provides an inexpensive, compact
and simple solution to their measurement problem and it protects
their customer's investment.
