Definition von thermocouples im Englisch Englisch wörterbuch
A temperature sensor consisting of a pair of wires of dissimilar metals Temperature is determined by measuring the differences in potential created at the junction of the two wires You must also have a thermocouple reference temperature sensor in order to measure the thermocouple For a thorough discussion, see the Measurements chapter in the datalogger manual
A transducer consisting of two different metals welded together at each end; a voltage is produced that is proportional to the difference in temperature between the two junctions (one of which is normally held at a known temperature)
A pair of dissimilar conductors joined to produce a thermoelectric effect and used to accurately determine temperature Thermocouples are used in laboratory testing of motors to determine the internal temperature of the motor winding
A device consisting of two dissimilar metals joined together at both ends The thermoelectric voltage developed between the two junctions is proportional to the temperature difference between the junctions Thus the device is used to measure the temperature at one of the junctions when the other is held at a fixed, known temperature
A device which converts thermal energy directly into electrical energy In its basic form it consists of two dissimilar metallic electrical conductors connected in closed loop Each junction forms a thermocouple See thermopile If the junctions are at different temperatures, an electrical potentials proportional to the temperature difference will exist in the circuit; the value of the potential generated is different for various combinations of materials For meteorological purposes couples of copper and constantan are frequently used; these generate approximately 40 microvolts per degree C of couple temperature difference
A temperature sensor formed by joining two dissimilar metals and applying a temperature differential between the measuring junction and the reference junction
A device for measuring temperatures, consisting of lengths of two dissimilar metals or alloys that are electrically joined at one end and connected to a voltage-measuring instrument at the other end When one junction is hotter than the other, a thermal electromotive force is produced that is roughly proportional to the difference in temperature between the hot and cold junctions
A combination of two dissimilar metals having a junction which can be maintained at the temperature it is desired to measure in terms of thermo-electric current produced
an instrument for measuring temperature, usually constructed of two dissimilar metals joined at one end, or both ends, for producing a thermo-electric current which is transmitted to a scale for direct reading
A thermocouple as commonly used is made by soldering or fusing two dissimilar metal wires together By connecting the wires to a potentiometer, the temperature at the junction can be determined Copper constant thermocouples are usually used in dry kiln work
Used as temperature sensors within a robot's sensing system Consists of two dissimilar metals that produce an electromotive force roughly proportional to the temperature difference between their hot and cold junction ends
A device made of two unlike metals that generates electricity when there is a difference in temperature from one end to the other Thermocouples have a hot and cold junction
A temperature-sensing element which converts thermal energy directly into electrical energy In its basic form it consists of two dissimilar metallic conductors connected in a closed loop Each junction forms a thermocouple If one thermocouple is maintained at a temperature different from that of the other, an electrical current proportional to this temperature difference will flow in the circuit The value varies with the materials used Couples of copper and constantan, which generate approximately 40 microvolts per °C of couple temperature difference, are often used for meteorological purposes
A device for measuring temperatures by the use of two dissimilar metals in contact; the junction of these metals gives rise to a measurable electrical potential with changes in temperature
The junction of two dissimilar metals which has a voltage output proportional to the difference in temperature between the hot junction and the lead wires (cold junction) (refer to Seebeck emf)
A device used in controlling gas valves consisting of two junctions of dissimilar metals When the two junctions are at different temperatures, a voltage is generated
A temperature sensor created by joining two dissimilar metals The junction produces a small voltage as a function of the temperature Consists of two dissimilar metals joined together, making a continuous loop When one junction has a different temperature from the other an electromotive force (voltage) occurs There are several types of thermocouples, constructed from different metals and with differing temperature ranges
Popular temperature sensor because of its low cost, versatility and ruggedness Consists of two different metals joined together, making a continuous circuit When one junction has a different temperature from the other an electromotive force (voltage) occurs There are several types of thermocouples, constructed from different metals and with differing temperature ranges and accuracies
or thermal junction or thermoelectric thermometer Temperature-measuring instrument consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower (reference) temperature. A measuring instrument is connected in the electrical circuit. The temperature difference causes the development of an electromotive force that is approximately proportional to the difference between the temperatures of the two junctions. Temperature can be read from standard tables, or the instrument can be calibrated to display temperature directly
a kind of thermometer consisting of two wires of different metals that are joined at both ends; one junction is at the temperature to be measured and the other is held at a fixed lower temperature; the current generated in the circuit is proportional to the temperature difference
A heat-sensing device made of two conductors of different metals joined at their ends An electric current is produced when there is a difference in temperature between the ends
