Description
Unistate models
of the series T300 / cc401, cc402 are
extremely dynamic temperature
control devices,
which are designed for
externally closed
as well as for
externally open
applications
. Compared to conventional bath and circulation thermostats, these devices
do not have an
internal bath
.
These temperature control devices are primarily offered for high heating loads. They
also have a cooling water connection to perform temperature reductions and to
compensate for self-heating.
Cooling power control
is only done in the
w HT
series of
machines.
Due to their
small volume
, combined with
high-performance heating technique,
they
achieve respectively
short heating-up times
and
cooling rates
compared to conventional
bath and circulation thermostats.
Instead of a tempering bath, which catches the expansion of the thermal fluids in
dependence of the temperature with conventional bath and circulation thermostats, a
passively tempered expansion vessel
is used here.
With the integrated
speed controlled pump
fitted which is used in table and
freestanding models, the
volume flow
or the
pressure
of the thermal fluid can be
regulated alternatively and can therefore be adjusted optimally to the application at
hand. With freestanding models with larger pumps, this task can be performed by the
external optional VPC module.
By means of the
self-optimising cascade regulator
you will achieve
optimal regulator
results
regarding regulating / unregulating performance, as well as with
set-point
changes
and
exothermal reactions
. You can choose to thermoregulate aperiodical or
with a slight overoscillation (faster).
You can
comfortably read
information and temperature curves and
enter data
via the
large graphic display (with touchscreen).
A
comfortable menu guide
facilitates the operation of the temperature control device.
With help of the
digital interfaces RS232 and RS485, the analogue
0/4-20mA or 0-10V current interface and various digital input / output possibilities (all
as per NAMUR)
, the temperature control devices can easily be integrated into multiple
laboratory automation systems.
The
removable Unistat Pilot / CC-Pilot
can also be used as a
remote control
.
External temperature control tasks
can easily be performed via a
Pt100 connection (as
per NAMUR
).
The
integrated temperature ramp function
as well as the
internal temperature
programmer
underline the high level of operator comfort. The integrated programmer
offers the possibility to make and then call up 10 temperature programs with a
maximum of 100 steps.
The thermostat uses an
over-temperature protection
in accordance with
DIN EN 61010-
2-010,
which is
independent
of the actual control circuits.
