The Future Proof Rheometer
What is new in the MCRxx2?
The new MCR xx2 features a totally new electronics and mechanical designand relies
on the further improved core componentssuch as EC-motor, air bearing and normal
force sensor.
Development targets
1) Fill the foot steps of the MCRxx1 (Release Status)
First step ensures MCRxx1 performance on the MCRxx2 platform and some unique new
additional features.
Since there were constantly small improvements in the MCRxx1 the last specifications
were to conservative. Therefore the MCRxx2 specifications are better compared to the
MCR xx1 specs.
2) New platform which can grow with further needs from customers.

Characteristics of the EC-Motor
Known and constant magnetic field
Fast and accurate control routines
Instantaneous availability of the
magnetic field and the torque, i.e. no
time lag due to induction
Extremely fast response times.
Controlling of very small speeds at small
torques. Oscillation at higher frequencies
No induction needed: No eddy currents. No heat production on the
rotor- No change in motor characteristics. High torques for long times
possible (300 mNm).
Linear relationship between the electro-magnetic torque and the
stator current( M I): Only onemotor constant for calibration
Almost no dependence on the type of geometry, i.e. no
difference between small low inertia and large high inertia
geometries.

Air Bearing / Normal Force
AxialBearing

Sensor
Air bearings
Axial bearing centers the shaft
Radial bearing holds the rotating part
Constant high quality (less variation) of air
bearings due to improved manufacturing process
MCR502: Temperature stabilisation of the air
bearing increases the lifetime of motoradjustments and reduces drifts in normal force.
Normal Force Measurement
Patented normal force sensor in the air bearing measures
the natural deflection of rotor when measuring system is
pushed or pulled by an electrical capacity method.
Benefits:
Large NF range with high resolution
NF measurements in fast transient measurements
Measurement in the air bearing NF available for all
environmental systems and accessories
NF is no extra option or accessory

Normal Force Sensor MCR52
High normal forces when occurring during gap loadingof highly viscous samples can potentially damage the
mechanical bearing of the MCR150/51 because the
bearing is not designed for high axial load and there is
no sensor which recognizes such an event
Normal Force sensor MCR52
The MCR52 employs a normal force sensor which
recognises potentially dangerous events for the ball
bearing and stops the actual movement.

TruStrainTM
LAOS has become more popular in the last two years, which allowed us
to improved and show the performance of the DSO controller.
The name DSO is not protected, competition has therefore also
introduced Direct Strain names just for simple amplitude control in
oscillation.
To differentiate real time position control from the amplitude control and
to underline the improvements of this controller over the last years a new
name for former Direct Strain Oscillation is introduced with the MCR xx2:
TruStrainTM
Strain Control in Oscillation: Amplitude

T-ReadyTM
Setting of sample temperature
Today the waiting time for sample temperature before test start is usually longer
then required to ensure that the sample reached the desired temperature.
Nevertheless there is still no proof that the sample has really reached the desired
temperature.
T-ReadyTM
T-Ready ensures the desiredsample temperature.
Reduces and optimizes waiting times.
Uses the TruGapTMhardware and functionality to detect sample temperature
equilibrium
8/10/2019 Rheometer Family MCRxx2

T-ReadyTMTechnology / Measurement
Hardware:TruGapTMtemperature device and measuring system
Idea:Sample contacts the bottom plate and measuring system. As long as the temperature of the
sample, temperature device and measuring system is not in equilibrium the lift motor is in motion and
compensates the gap continuouesly according to TruGapTMmeasurement. At temperature equilibrium
the lift motor motion stops moving. This is recognized and the test is started automatically.
Temperature Criteria:
If the lift motor does not move more
then 3 m within the last 200 s a
constant temperature within the gap is
reached. Instrument shows on display
in green T-Ready.
The criteria can be set in the servicesoftware. 3 m within 200 s ensures
accurate temperature for all types of
measuring systems.

New Intuitive Colour Display
Colour display
New, intuitive, well-organized colour display controlled with
soft keys.
The display employs the same functionality as a touch
screen but without the risk of damaging the screen with
dirty fingers when working with samples like e.g. asphalt or
paints
Users have just to press a few buttons at the display instead of do some
handling in the software.
Network control of the instrument gets even more interesting because
sample and instrument preparation does not require computer interactions.
