It is used on older gas trains to furnaces, water heaters ect. to prove that a pilot light is lit. The pilot heats to dissimilar metals such as copper and steel and craetes a small electric current that will allow the main gas valve to open when the fuel is called for by the stat. The current does not open the valve it simply tells the valve that it is okay to open because the pilot light is lit. In more modern systems a uv sensor ( ultra violet) will sense the light of the pilot to open the main gas valve.........Hope this helps,

What else can I help you with?
What type of colour are use to paint thermocouple?
You should not paint a thermocouple.
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.
Do you need to use TC extension wire to connect a thermocouple or can you use shielded cable?
You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.
What do you use a THermocouple for?
measuring temperature difference
How can you determine if a thermocouple is bad?
To determine if a thermocouple is bad, you can use a multimeter to measure the voltage output. If the voltage is not within the expected range, it may indicate that the thermocouple is faulty. Additionally, you can visually inspect the thermocouple for any signs of damage or wear.
How can I determine if a thermocouple is bad?
To determine if a thermocouple is bad, you can use a multimeter to measure the voltage output when the thermocouple is heated. If the voltage reading is not within the expected range, it may indicate that the thermocouple is faulty. Additionally, visually inspecting the thermocouple for any signs of damage or wear can also help determine if it is bad.
How can I test a thermocouple on a water heater to ensure it is functioning properly?
To test a thermocouple on a water heater, you can use a multimeter to measure the voltage output. Disconnect the thermocouple from the control unit and place the multimeter probes on the thermocouple terminals. A functioning thermocouple should produce a voltage reading within the expected range. If the reading is outside this range, the thermocouple may need to be replaced.
How do you measure the temperature of a furnace?
You could use a thermocouple.
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.
What kitchen utensil is used for measuring temperature?
you use a thermocouple instrument
How can I test a water heater thermocouple to ensure it is functioning properly?
To test a water heater thermocouple, you can use a multimeter to check for continuity. Disconnect the thermocouple from the control valve and set the multimeter to the resistance setting. Touch one probe to the tip of the thermocouple and the other probe to the base. If the multimeter shows a reading of around 25-35 millivolts, the thermocouple is functioning properly.
How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
