Wherever
temperatures are measured, temperatures
must also be simulated. The Pt-simulator
is suitable for a wide area of
applications. It has a wide range of
simulation, which is resolved in 0.1 deg.
C steps and makes many assignments in
chemistry-, measuring-, controlling-,
medicine and household applications, food
industry, vehicle construction, air- and
space travel and power plants easy to
solve. Often in the past several
simulators had to be used alongside to
achieve either resolution or the range of
the relevant application. As an extra
advantage to the user temperatures can be
entered in degrees celsius. Additional
extensive conversions and readings in
tabulation sheets are no longer
necessary.

| Description |
 |
There are five
precision decade switches in a sturdy
metal housing. The desired temperature
value is selected in four steps with a
0.1 degree celsius resolution in ranges
from - 100 degree celsius to max. 500
degree celsius. According to DIN EN 60751
the precision resistors simulate the
temperature values for the Pt 100
resistor. The simulated temperature value
is called on the output plugs
"R". If required, the line
resistance can also be simulated in steps
of 10, 20 and 30 Ohm. The celsius scale,
displaced by 273,15 K opposite the
absolute temperature stipulates that an
additional switch-over of polarity is
performed at negative celsius temperature
values. The simulator is of a high ohmic
at wrongly entered + or - signes. An
unintentional misuse is practically
impossible. The switches are implemented
in a short-circuit control manner. The
precision resistors in the 100 deg.
decade will therefore be switched
parallelly at the moment of switch-over,
in all other decade steps there is no
effect at switch-over. The used resistor
material MANGANIN ® has a temperature
coefficient smaller 10 ppm/K. This makes
a consideration of the environmental
temperature normally superfluous.
