GENERAL
The TV-series is intended for temperature control of
applications requiring a high degree of stability over a
broad temperature range. The robust construction
including advanced safety features give the bath a
range of wide application.
The heat input is controlled by a microprocessor system.
A
special
optimized
electronic
temperature
measurement circuit ensures an extremely high degree
of accuracy and reproducibility of operation conditions.
The baths feature a standard RS232C interface for
communication with a computer. Please download our
free communication software "Tamcom" from the
website.
The baths standard features include an integrated
cooling coil enabling for rapid reduction of its
temperature or alternatively enabling control around or
slightly below ambient temperature.
5.1
Construction
The TAMSON baths are constructed entirely from
corrosion-resistant materials such as stainless steel and
PTFE (Teflon).
A thick layer of rock wool between the inner bath and
outer casing ensure effective insulation. It improves
temperature stability and lowers the casing temperature
when the instrument is used at high bath temperatures.
The central microprocessor within the control module
manages and controls, the functions for temperature
measuring regulation, program storage, safety control
and error coding.
5.2
Temperature control and setting
The bath temperature is regulated using a PT100
temperature
probe
which
is
connected
to
a
microprocessor module. The advanced electronic
control system continually computes the energy input
required for optimal temperature accuracy and stability.
The controller will activate the heaters partially or in full,
taking into account the difference between actual bath
temperature and set point.
The required temperature is set by three membrane
switches on the front panel. Read-out is on LCD. An
absolute temperature offset is provided with a resolution
of 0.01°C (0.001°C for the TV4000MKIIDC) and a
specific offset of 0.005°C is available from the menu.
