  5. The Slogan for the MCR Series: Your Future-Proof Rheometer What does this slogan mean? New high-end rheometer platform employing state of the art technology for all today´s and future applications Continuous firmware development ensures performance improvements and new functions over the life time of the MCR xx2. The accessories for the former MCR as well as all new accessories can be used in the new MCR rheometer series. … and now the technical details

  6. The Future Proof Rheometer • What is new in the MCRxx2? • The new MCR xx2 features a totally new electronics and mechanical design and relies on the further improved core components such as EC-motor, air bearing and normal force sensor. • Development targets • 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.

  7. Instrument Shape of MCR xx2 Series • MCR Series with 4 instruments: • MCR 52(ball bearing) • MCR 102 (air bearing) • MCR 302 (air bearing) • MCR 502 (air bearing) • MCR 52, 102, 302 look similar • MCR 502 • higher frame • larger flange

  8. MCRxx2 - EC-Motor, Motor Controller, Electronics Innovations of MCR xx2 • TruRateTM (new) • TruStrainTM (new) • TruGapTM and CTD boards included • Digital current sources • T-ReadyTM (new) • New faster electronics

  9. 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 one motor constant for calibration • Almost no dependence on the type of geometry, i.e. no • difference between small low inertia and large high inertia • geometries.

  10. Air Bearing / Normal Force Radial Bearing Air bearings • Axial bearingcenterstheshaft • Radial bearingholdstherotatingpart • Constant high quality (lessvariation) ofairbearings due toimprovedmanufacturingprocess • MCR502: Temperaturestabilisationoftheairbearingincreasesthelifetimeofmotoradjustmentsandreducesdrifts in normal force. Normal Force Sensor Axial Bearing 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

  11. Performance MCR xx2Normal Force, TruRateTM,SRM2490 CSRTest, TruRateTM CP25-4, P-PTD200, 25°C Shear rate: 0.001 to 100 Measurement point duration. 100 to 1 s (log) Averaging: Automatic Min Normal Force: 0.0028 N Spec values: Normal Force Range: 0.005 to 50 N

  12. Normal Force Sensor MCR52 High normal forces when occurring during gap loading of 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.

  13. Performance MCR xx2TruRateTM, Water Measurement CSR Test, TruRateTM CP50-1, P-PTD200, 25°C Measurement point duration 10 to 100s Averaging: 80% of the measuring point duration Flow curve water: Within 10% deviation down to 15 nNm

Performance MCR xx2TruRateTM, Step Rate SRM 2490 CSR Test, TruRateTM CP25-4, P-PTD200, 25°C Shear Rate: 1,3,5,10 s-1 Measurement point duration. 0.001 to 10 s (log) Averaging: Automatic 35 ms at 3,5,10 s-1 15 ms at 1s-1 • Desired shear rates reached within 15 to 35 ms • Viscosity curves overlaying • First Normal Stress coefficient perfectly overlaying

  16. 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

  20. 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 desired sample temperature. • Reduces and optimizes waiting times. • Uses the TruGapTM hardware and functionality to detect sample temperature • equilibrium

  21. T-ReadyTM Technology / Measurement Sample: Canon Silocone oil Shear rate: 10 s-1 Measurement point duration: 5 s Hardware: TruGapTM temperature device and measuring system Temperature Criteria: If the lift motor does not move more then 3 µm 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 service software. 3 µm within 200 s ensures accurate temperature for all types of measuring systems. Less then 3 µm movement within 200 s  TReadyTM Display 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 TruGapTM measurement. At temperature equilibrium the lift motor motion stops moving. This is recognized and the test is started automatically.
