Resistance of a wire coursework graph

Most people specifying RTD probes have to pay attention only to the chemical compatibility that will prevent corrosion. This is generally straightforward and guidelines can be taken from other materials used in the system in which the RTD will be installed. If the piping system is constructed of 316 ., then the probe probably should be also. But always check a corrosion guide for corrosion rates and material recommendations if you have the slightest doubt.

For applications involving thermowells, the thermowell will carry the burden of corrosion protection. However, be sure to protect the connecting wires and any terminals or plugs from possible corrosion caused by splash or corrosives in the atmosphere.

JELLIFF Alloy C/O/J, with a resistivity 30% higher than any other alloy available, literally creates a new range of miniaturization for precision fixed and variable resistors. For a given volume, wire wound resistors can be one-fourth smaller, or one-third more resistance can be wound into a given volume than with 800 ohm alloys. Jelliff Alloy C/O/J exhibits a flat T/C curve of ±5 ppm over the temperature range of -55°C to 25°C and 25°C to 150°C. On a limited basis T/C's are available down to ±1 ppm over a shorter temperature range. Its ... JELLIFF Alloys 30, 60, 90 and 180 (124)
These lower-resistivity Jelliff alloys provide a graduated series (the grade numbers indicate resistivity in ohms/.) for use in low-ohmage units, including fixed resistors, rheostats, relay windings, and "heater cord." This wide choice of resistivities also allows the use of the most desirable diameter for proper resolution in potentiometers.

Bare wire will be provided unless other tolerances are required.
