Table 1 lists maximum service temperatures for long term exposures of bare wire thermocouples. For very short exposure times, temperatures of the fine gage thermocouples can be as high as the permissible temperatures for the 0.8 mm (0.032") diameter thermocouples.
** Do not expose to oxidizing atmospheres.

*The time constant is defined as the time required to reach 63.2% of an instantaneous temperature change. The data for Table 2 are obtained by measuring the time required for a Type J fine gage thermocouple to reach 63.2% of its final temperature when its junction is alternately exposed to two different temperature levels. In this case, the time constant was measured for exposures between 427°C (800°F) and 38°C (100°F) air between 93°C (200°F) and 38°C (100°F) water.

Fine Gage Thermocouples
OMEGA® fine gage thermocouples are used whenever fast, accurate temperature measurements are required. The fine wire diameters enable accurate temperature measurements without disturbing the base temperature of the body, in which the installation is made, by keeping heat transfer via the leads to a minimum. Also, the fine junction permits accurate “pin-pointing” of the measured values. They are available in wire sized ranging from 0.0005" to 0.032" in diameter. All fine gage thermocouples are made from carefully selected materials. To insure consistent thermoelectric properties, each package contains thermocouples made from matched pairs of wire within the same lot number. When specified, several packages of thermocouples made from the same lot number can be supplied at no extra charge.

Response Time
While thermocouple response is a function of medium of submersion, wire diameter, alloy type and temperature level, it is possible to use Table 2 as a guide for comparing the various wire size thermocouples.


Important Ordering Notes

Base Metal Thermocouples
Prices given for 12 inch lengths (package of 5). Other sizes and lengths are available on special order. A 12 inch length corresponds to a 24 inch loop. To order longer lead lengths for base metal calibrations, add $4 per foot per package.

Platinum/Rhodium Thermocouples
Prices given for 6 inch lengths (sold individually). Other sizes and lengths are availableon special order. A 6 inch length corresponds to a 12 inch loop. To order longer lead lengths for Pt/Rh calibrations, see the table below.
