An instrument that
accurately simulates the Pt 100
resistance thermometer over a wide
temperature range is very useful for the
testing of industrial temperature
measuring and control devices. Pt 100
simulators of the types 4503, 4503 S and
4504 are the answer to such requirements.
A special advantage of these simulators
is the direct reading of the 30
calibration points in centigrades (0
°C), whereby an trouble-some checking
with tables is rendered unnecessary.
The standard simulator type 4503 has
30 fixed calibration points within a
range from -200 °C to 800 °C. Many
years of experience have shown the need
for the Pt 100 simulator type 4504 with
30 calibration points within a restricted
range from -30 °C to 100 °C. Such a
restricted temperature ranges is of great
interest, e. g. for the food industry. In
dairies, breweries, at ice-cream
factories and similar plants the Pt 100
simulator type 4504 is the measuring
instrument for daily use. Also this
simulator is used in industries
associated with household appliances, in
power and heating plants an the like.
Wherever measuring and control devices at
individual temperature points require
adjustment and testing the Pt 100
simulator type 4503 S should be employed.
In these instruments the selector switch
is programmed with 30 temperature
calibration points as individually given
by the user. The type 4503 covers a range
from -200 °C to 850 °C.
The Pt 100 simulators are small-sized,
rugged and designed for field
applications. A functional leather
carrying case, which is available as an
accessory, serves to protect the
instrument. Pt 100 simulators are also
well-suited for laboratory use.

| Description |
 |
A compact, sturdy
alu-housing, provided with 4 mm terminals
in industrial standard. accommodates a
high-class switch with wire-wound
precision resistors of MANGANIN ® . By
way of this selctor switch 30 fixed
temperature values according to DIN EN
60751 (specification for the resistance
thermo-meter Pt 100) are simulated. The
simulated resistor value which
corresponds to the selected temperature
will be picked up at the output terminals
"R sim ". Another three
terminal sockets serve to simulate
connecting cable resistances between 0
and 40 Ohm. The selector switch of type
4503 S is programmed with 30 temperature
calibration points as individually given
by the customer within a range from -200
°C to +850 °C. The resistance material
MANGANIN ® used in the instrument has a
temperature coefficient of < 10 ppm.
Therefore the ambient temperature needs
not to be taken into account.
