Applications Constantan is used for accurate resistors like thermo-couples, i Wheet-stone bridge, ii Low temperature heaters and iii Resistances Constantan Alloy Of all modern strain gauge alloys, constantan is the oldest, and still the most widely used. This situation reflects the fact that constantan has the best overall combination of properties needed for many strain gauge applications. This alloy has, for example, an adequately high strain sensitivity, or gauge factor, which is relatively insensitive to strain level and temperature. Its resistivity is high enough to achieve suitable resistance values in even very small grids, and its temperature coefficient ofresistance is not excessive.
Precision Temperature Specialists When you must make precise temperature measurements, Physitemp Instruments can provide you with a very accurate temperature monitor and Type T thermocouple microprobes. Physitemp thermometers have a resolution and accuracy of 0.
Other competitive electronic thermometers might have 0. These are five times more accurate over this range than competitive probes made with regular "Special Limits" wire. Small Fast and Accurate Temperature Probes Physitemp Instrument's miniature Type T thermocouple sensors provide the widest and most versatile selection of temperature probes available for bioscience and analytical chemistry applications.
All probes are interchangeable and do not require individual calibration when used with any of our Type T thermocouple instruments over the specified range.
Physitemp manufactures a wide range of interchangeable Type T thermocouple temperature probes. Temperature Controllers Physitemp Instruments can provide you with a very accurate temperature monitor and Type T thermocouple microprobes. Physitemp Type T Thermocouple Digital thermometers have a resolution and accuracy of 0.
These are five times more accurate than competitive probes made with regular "Special Limits" wire.The influence of a magnetic field on the Seebeck effect for a copper-constantan thermo- couple was studied. Measurements of the change in Seebeck voltage were carried out with only one thermocouple junction in the magnetic field at varying magnetic field and const- ant sample temperature.

The object of this manipulation is to calibrate a copper – constantan and an iron – constantan thermocouples at the bp of water and the mp of tin.
II-APPARATUS: Copper – constantan and iron – constantan. • The misrepresentation of papers, reports, assignments or other materials as the product of a student’s sole independent effort, for the purpose of affecting the student’s grade, credit, or status in the University;.
The materials can be broadly classified into two categories namely: (i) Conductors: Conductors are the substances through which electric charges can flow easily.
For example, the electrons of the outer shells of metallic atoms are loosely bound to the nucleus. Copper also has a very rich history. ³Copper History´ tells us that ³Copper was the first metal mined and crafted by man, and has been the most important one in the oldest times of history«The discovery of the process needed to obtain copper from its ores was a very important event in our history: an event which gave birth to metallurgy.
