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.
A thermocouple detects temperature.
is a thermocouple an active or passive transducer?-why?
Yes, it's an active transducer. A thermocouple is passive not active
The maximum sensed
thermocouple,piezoelectric transducer,photoelectric transducer.
Air Probe.
The output of the thermocouple is linear.
Yes, thermocouple is used in fridges !
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.
The thermocouple keeps a gas pilot light burning.
is a thermocouple an active or passive transducer?-why?
You should not paint a thermocouple.
not much, but it will depend on the type of thermocouple
Yes, it's an active transducer. A thermocouple is passive not active
The thermocouple is a sensore used to measure temperature. The thermocouple are made with two wires of different metals. joined together at one end to from a junction the thermocouple outputs in a a Milli volts .
Cause: Poor thermocouple contactSolution: Check the thermocouple
You don't, a thermocouple's output is in the millivolt range.
Is there any video on how to replace a thermocouple on a gas fireplace
