Caution!
Measuring device ME3-CP/PP
The cone/plate measuring device ME3-CP/PP may only be operated in the
temperature range of -10°C ... +90°C.
Caution!
Cooling device
Working in the temperature range of -20°C ... +180°C requires an additional
cooling device KE.
Caution!
Operation of the FTK-RST (water jacket)
When making tests at temperatures below -10°C and above +90°C, do not start
the temperature control device FTK-RST before the cooling liquid flows through
the cooling device KE-FTK-RST in order to avoid overheating of the rheometer!
Danger!
External thermostat / Cryostatic temperature regulator
Set the upper temperature limit at the external liquid circulation thermostat:
to +90°C if using water and to +180°C if using oil (with cooling device
KE-FTK-RST).
Typical thermostatting liquids are:
-10 °C ... +90 °C deionized water mixed with glycol
-20 °C ... +180 °C thermostat oil
Suitable thermostatting liquids can be obtained from Rheotec Messtechnik GmbH.
II.4.6 Assembly of KE Cooling Device
Figure II-5
Components:
1 Cooling device K-MK 2 Hose connections
Using the cooling device KE you can operate the temperature control device FTK-RST or
the measuring device KP adapter in the temperature range of -20°C … +180°C.
Flowing through the cooling channel of the cooling device, the cooling liquid prevents heat
transmission from the temperature-controlled measuring device to the RST Rheometer.
Assembly:
Turn the RST Rheometer off with the mains switch on the back of the instrument
Slide the cooling device KE onto the RST Rheometer from below and tighten the thread.
Fasten the hoses of the cooling circuit on the cooling device KE using the quick-fitting
hose coupling.
Cooling water connection to cooling device KE:
