Electronic Thermometer
All electronic systems need electrical
signals to work.
At the input stage we need to convert a
form of energy into an electrical signal.
At the output stage we need to convert
the electrical signal into another form of
energy.
Digital vs Analogue
Digital signals carry more information per
second than analogue signals.
Digital signals maintain their quality over
distance far better than analogue signals.
Thermocouple
What is the energy change which takes
place in the thermocouple?
The thermocouple converts heat energy
into an electrical signal.
The hotter the temperature the higher
the reading on the voltmeter.
The colder the temperature the lower the
reading on the voltmeter.
