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?
Yes, it's an active transducer. A thermocouple is passive not active
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.
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.
for temperature sensing i will suggest a RTD or A THermocouple. for temperature sensing i will suggest a RTD or A THermocouple.
a thermocouple is a sensor used to measure temperature under a wide variety of temperature ranges and condition
Cause: Poor thermocouple contactSolution: Check the 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.
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.
measuring temperature difference
The thermocouple does not actually measure temperature, but the temperature difference between two points. If the temperature at one point is known (reference junction) then the temperature of the other point (sensing junction) can be calculated.
This maintenance ensures a constant Electro Motive Force E. A relationship develops between the EMF and the Neutral temperature by an equation.
The thermocouple which measured the car's coolant temperature failed and so the car overheated.
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
You could use a thermocouple.
