What else can I help you with?
What kind of probe would you attach to a thermocouple or thermistor to measure the temperature inside an oven?
Air Probe.
What is the role of thermocouple?
Thermocouple is a heat sensing device.It is made up of 2 dissimilar metals twisted/joined at one end called a junction and that is made Hot and the other end or tell end is cold (may be at 0 degree C). then a voltage is developed accross the two dissimilar metal, this principle is called SEEBECK EFFECT.The voltage developed is directly propersional to the difference in temperature.
Is a thermocouple an active or passive transducer-why?
is a thermocouple an active or passive transducer?-why?
Is thermocouple a transducer?
Yes, it's an active transducer. A thermocouple is passive not active
Difference between thermistor and temperature sensor?
A thermistor is a temperature measuring device which acts like a temperature sensitive resistor. It is an active device that requires a current flow to measure its resistance so that the temperature may be calculated and/or displayed. A thermocouple is a device composed of two dissimilar metals fused together. An electrical potential occurs across the junction of the metals. As the potential is influenced by the temperature of the metal junction the output voltage can be measured and calibrated to show the temperature at the joint. Both devices may be employed to measure the temperature within a fixed space, or on a probe to measure the temperature at a remote point or points.
Does neutral temperature depend up on temperature of cold junction?
No, the neutral temperature in a thermocouple circuit does not depend on the temperature of the cold junction. The neutral temperature is the temperature at the point where the net electromotive force of the thermocouple is zero, and it is determined by the characteristics of the thermocouple materials and the temperatures at the two junctions.
In a thermocouple the temperature of the cold junction is 20oC the temperature of inversion is 520oC What is The neutral temperature?
the neytral temp will be 520 degree cel,as it is the temp pointing the EMF limit ,it doesn't have nything to do with span or the temp diff.
Which type of temperature senseing instrument you use in industry?
for temperature sensing i will suggest a RTD or A THermocouple. for temperature sensing i will suggest a RTD or A THermocouple.
Thermal manifold temperature instability ?
Cause: Poor thermocouple contactSolution: Check the thermocouple
What type of elements are used in different type of thermocouple?
Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. They are used with thermocouple temperature probes, bimetallic devices that are suitable for various temperature sensing applications.
What does a thermocouple do and how does it function in measuring temperature?
A thermocouple is a device that measures temperature by detecting changes in voltage when there is a difference in temperature between two different metals. When one end of the thermocouple is heated or cooled, it creates a voltage that is proportional to the temperature difference. This voltage is then converted into a temperature reading by a thermometer or temperature controller.
Which materials could you use to create a thermocouple?
To create a thermocouple one needs thermocouple wire, a means of spot welding the wire, and wire strippers. A thermocouple is used to measure temperature.
What do you use a THermocouple for?
measuring temperature difference
Why negative temperature in j thermocouple?
A negative temperature reading in a J-type thermocouple can be caused by a reversed connection of the thermocouple wires, which leads to the temperature measurement being incorrect. Check the polarity of the wires and make sure they are correctly connected to avoid this issue.
Why the cold junction in a thermocouple maintained at 0 degree celsius?
This maintenance ensures a constant Electro Motive Force E. A relationship develops between the EMF and the Neutral temperature by an equation.
What is the mill volt reading of a good thermocouple?
A good thermocouple typically reads around 1 to 30 millivolts when exposed to its rated temperature range. The exact millivolt reading can vary depending on the type of thermocouple and the temperature it is measuring.
What is a sentence using the word thermocouple?
The thermocouple which measured the car's coolant temperature failed and so the car overheated.
