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

Radial Bearing

Normal

Force

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


21/29

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.
