Application Pt 100 Simulator,
Model 4511 with temperature values according to customer specification

The Pt 100 simulator is used wherever measuring instruments or controlling systems have to be adjusted and tested with individually selected temperature values. Of course it can also be used if the temperature values of our standardized types do not fit.

The design model 4511 has been developed for customers with a need for higher quantities of identical items having the same temperature values. The minimum order quantity is 10 items.

Application Pt 100 Standardized Simulator,
Model 4512

An instrument that accurately simulates the resistance thermometer over a wide temperature range is very useful for the testing of industrial temperature measuring and control devices.The standardized simulator type 4512 is the answer to this challenge. A special advantage of this simulator is the division of the scale in centigrades (°C). Trouble-some checking with tables is rendered unnecessary.

Description

In a little compact, sturdy plastic housing is put a high-class switch with wire-wound precision resistors of MANGANIN®. Using this selector switch 11 fixed temperature values according to DIN EN 60751 of the resistance thermometer Pt 100 are simulated. The simulated resistance value, which corresponds to the selected temperature, will be picked up at the terminals “R_sim”. Two other terminal sockets serve to simulate connecting cable resistances between 10 and 20 Ω.

The selector switch of types 4511 and 4512 is programmed with 11 temperature values as individually given by the customer. Within a range from -200°C ... +850 °C each temperature value can be selected. The resistance material MANGANIN® used in the instrument has a temperature coefficient of < 10 ppm. Therefore the ambient temperature needs not be taken into account.
