Thermocouple Sentence Examples
This law is commonly applied in connecting a thermocouple to a galvanometer with coils of copper wire, the junctions of the copper wires with the other metals being placed side by side in a vessel of water or otherwise kept at the same temperature.
The method appears to be open to the objection that the difference of temperature reached in so long an interval would be more or less independent of the thermal 0 0 .20 h ?1 capacities of the calorimeters, and would also be difficult to measure accurately with a thermocouple under the conditions described.
Returning again to the equations already given in § i i for an elementary thermocouple, we have the following equivalent expressions for the E.M.F.
The 10 thermocouple probes protrude into the gas stream at the power turbine entrance (station 45 ).
Specimen heating is preferably achieved by direct resistance heating of conducting specimens and monitored by a calibrated thermocouple attached directly to the specimen.Advertisement
In this case the testpiece monitoring thermocouple must have sufficiently long trailing leads to accommodate the opening of the furnace.
At first sight the effect of changing the type of thermocouple used to measure the heat input would appear to be insignificant.
The flame should be focused on the thermocouple probe.
What type of thermocouple wire should I use for profiling surface mount boards?
The user selects J, K, T or J DIN thermocouple input from the front panel.Advertisement
Typically, thermocouple measurements around a furnace are highly correlated.
Practically it is impossible to manually keep track of the many hundreds of thermocouple signals that may be presented to an operator.
Thermoelectric materials can also be used in cryotherapy, pacemakers, and as thermocouple sensors.
We conclude by applying Ohm's law that the electromotive force, E, of the thermocouple may be approximately represented for small differences of temperature by the formula E=CR=p(t-t').
If C is the intensity of the current through a simple thermocouple, the junctions of which are at temperatures t and 1', a quantity of heat, P X C, is absorbed by the passage of the current per second at the hot junction, t, and a quantity, P X C, is evolved at the cold junction, t'.Advertisement
Seebeck found that the metals could be arranged in a Thermoelectric Series, in the order of their power when combined with any one metal, such that the power of any thermocouple p, composed of the metals A and B, was equal to the algebraic difference (p'-p") of their powers when combined with the standard metal C. The order of the metals in this series was found to be different from that in the corresponding Volta series, and to be considerably affected by variations in purity, hardness and other physical conditions.
