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.
6.1
Construction
The TAMSON baths are constructed entirely from
corrosion-resistant materials such as stainless steel
brass and 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.
6.2
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. This
