Functional Elements

9.2 External filter

An external filter is part of the standard range of items
supplied with the temperature control units for Series 1
TCP/P (Peltier-Temperature control system), TCE/P
(electrical temperature control unit), TCL/PO (liquid
temperature control unit for HAAKE RheoScope) and the
UTCP/P (Peltier-Temperature control system for HAAKE
RSXXX units). It consists of the filter itself, a plastic cone
contained inside it, and clamps.
Using this filter enables the interior of the relevant
temperature control unit to be protected against any
impurities carried in by the temperature liquid. The external
filter represents an additional protection. On the standard
model a sieve is built in to the intake of each temperature
control unit.
As shown in Fig. X, the filter is installed in the intake hose
leading into the temperature control unit between the
thermostat and the measurement instrument. The intake
and outlet directions must be noted (IN and OUT on the
filter). It is fastened with the clamps that are supplied with it.
Hoses with a diameter of 8 mm can be installed and fastened
with the clamps supplied. The plastic cone on the inside of
the filter serves as a direction of flow indicator, and its
movements show the through-flow of the tempering liquid. If
there are impurities in the filter it can be taken out, cleaned,
and used again. The use of the external filter is
recommended because any impurities can be recognised
and removed more readily than with the sieve that is built in
to the temperature control unit. The screw-in sieve (internal)
must of course be checked for impurities from time to time
in order to ensure the functional capability of the temperature
control unit.
