FTK temperature control device (water jacket) and measuring systems in Figure II-3:
1 FTK water jacket 5 Measuring bob CC3-14
2 Sample cup for FTK-RST 6 Measuring bob CC3-25
3 Immersion type sample cup 7 Measuring bob CC3-40
4 Measuring bob CC3-8
Assembly:
• Turn the RST Rheometer off with the mains switch on the back of the instrument.
• If the cooling device KE is to be used, mount it first.
• Set the FTK from below on the mounting flange for the sample cup and tighten the thread.
• Fix the hoses for the liquid circulation thermostat (see below).
• Plug the cable “VK-MB” supplied with the FTK into the built-in Pt100 and into the “Pt100”
socket on the back panel of the RST Rheometer.
Thermostat connection to the FTK temperature control device:
• Hose connections are required to connect a liquid circulation thermostat when the RST
Rheometer is operated with the FTK temperature control device.
• The hoses from the liquid circulation thermostat are connected with the FTK temperature
control device (see Figure II-2, page 16) using the quick-fitting couplings.
• For that purpose you push the coupling sleeve slightly back, insert the hose connector
and let the coupling go. It will fasten the hose (without screwing or turning) by locking in.
Pull lightly to check if the hoses fit tightly.
Danger!
External thermostat / Cryostatic temperature regulator
Set the upper temperature limit at the liquid circulation
thermostat to 90°C if using water and to 180°C if using oil (only
with KE cooling device!).
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.
Caution!
Operation of the FTK
When making tests at temperatures below -10°C and above
+90°C, do not start the temperature control device FTK before
the cooling liquid flows through the KE cooling device in order to
avoid overheating of the rheometer.
