Beskrivelse

OMEGA™ fine-diameter 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 diameters ranging from 0.05mm to 0.81mm. All fine-gauge thermocouples are made from carefully selected materials. To ensure consistent thermoelectric properties, each pack contains thermocouples made from matched pairs of wire within the same batch number. When specified, several packs of thermocouples made from the same batch can be supplied at no extra charge.

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.

Base Metal Thermocouples. (Supplied in packs of 5)
Prices given for 300mm lengths. Other diameters and lengths are available on special order. A 300mm length corresponds to a 600mm loop.

Platinum/Rhodium Thermocouples. (Supplied individually)
Prices given for 150mm lengths. Other diameters and lengths are available on special order. A 150mm length corresponds to a 300mm loop.

Maximum Service Temperature (Table 1)

Thermocouple Type	0.13 mm	0.38 mm	0.51 mm	0.81 mm
J**	315°C	371°C	371°C	482°C
K	593°C	871°C	871°C	982°C
N	593°C	871°C	871°C	982°C
T	149°C	204°C	204°C	260°C
E	315°C	426°C	426°C	593°C
R,S	-	-	1450°C	1450°C
B	-	-	1700°C	1700°C

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

Thermocouple Response Time* (Table 2)

Wire Dia. mm	Still Air 427°C/38°C	18 m/sec Air 427°C/38°C	Still Water 93°C/38°C
0.125	1.0 sec	0.08 sec	0.04 sec
0.381	10.0 sec	0.80 sec	0.40 sec
0.75	40.0 sec	3.2 sec	1.6 sec

*The time constant is defined as the time required to reach 63.2% of an instantaneous temperature change. The data for Table 2 is obtained by measuring the time required for a Type J fine-gauge 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 and 38°C in air and between 93°C and 38°C in water.
