5.4.3 Special Measuring SystemsIn addition to the standard measurement systems according to DIN 53018 and DIN 53019 (cylinder measuringsystems, cone/plate and plate/plate measuring systems P1 to P4) also special measuring systems can beused. Special measuring tasks can be realized by those measuring systems, e.g. viscosity measurement ofstrongly sedimenting suspensions. The main intention of using special measuring systems is to getreproducible results. With special measuring systems, torque, speed, characteristics or relative viscosities canbe measured. The exact calculation of shear stress and shear rate and its distribution is not possible.vane rotors: F1, F2, F3, F4vane rotor F1 (for measuring cup G1 or free rotating)measuring cup diameter: 38 mmvane diameter: 34 mmwithout holes(recommended for cosmetics, creams)recommended viscosity range: 20...10 5 mPa svane rotor F2 (for measuring cup M1 or free rotating)measuring cup diameter: 18 mmvane diameter: 14 mmwithout holesrecommended viscosity range: 100...10 5 mPa svane rotor F3 (free rotating, for glass vessel)long stabvane diameter: 34 ммwith holes(recommended for suspensions, starch)recommended viscosity range: 20...10 5 mPa svane rotor F4 (for measuring cup G1 or free rotating)measuring cup diameter: 38 mmvane diameter: 34 mmwith holes(recommended for materials with solids andsuspensions)recommended viscosity range: 20...10 5 mPa sCrown sensorFor the investigation of plaster and masonry mortar andother inhomogeneous productsClaw stirrerFor the investigation of highly solids-containing andsedimenting materials to be measured18
5.5 Peltier Tempering SystemThe precise rheological measurements require the exact keep of the defined temperature conditions for themeasurement method and the measuring material (as the lowest possible temperature gradient). For thatpurpose, a highly accurate temperature measurement and a temperature control are necessary. Both can beguaranteed through a two-sided, precisely controllable Peltier tempering of the measuring chamber, which canbe supplied complete with the rheometer RHEOTEST ® RN.By using the basic plate an automatic distance adjustment, the upper tempering element is integrated into theadapter and the lower temperature-regulating element is integrated into the base plate, immediately below theexchangeable plate with the material to be measured.5.5.1 Peltier Control UnitThe Peltier control unit assures power necessary for temperature control. It operates on the basis of a microprocessor.The micro-processor fulfils all tasks regarding the regulation, safety control and softwarecommunication. The software permits control of temperature changes in jump and in ramp.The device can actively heat and cool.The general view of Peltier control unit is shown in Figure 9. An LCD-Display (1) is located on the front panel,which displays the following parameter: set temperature (topleft); actual temperature (top right); operation mode (down 100,00 Ist: 65,21left): MAN = manual operation, REM = Remote, control viaPC; status indication (down center): START = tempering,MAN START 65,2 %STOP = Peltier is switched off; actual tempering in % (downright).The temperature can be regulated manually using the operation buttons (2). LED-Light (4) indicates an error.The glow of the LED-lamp (5) means the heating mode, the LED-lamp (6) – the cooling mode. The coolantreservoirs (7) is located on the front panel of Peltier control unit. On the top of the coolant reservoir is thescrew-on lid of the reservoir (3) for filling up the cooling liquid.The on / off switch of the device (8) can be found on the lower side.Following interfaces and connectors are arranged on the back side of the Peltier control unit: the interfaceconnection to the computer (9), connections for energy supply (10) and for Pt100 temperature sensor (11) forconnection with the basic plate, mains supply (12) and hose connections to the basic plate (13).Please note that the hose connections (13) are arranged according to the appropriate label (1 or 2).19
