Applications of Electrical Resistance Thermometer
Applications of Electrical Resistance Thermometer
Points : Applications of Electrical Resistance Thermometer
A part from its use in resistance thermometers for direct temperature measurement, the effect
of cooling of a heated resistance element due to the flow velocity of gases is also exploited
in hot wire ammeters to measure the flow velocity.
The increase in temperature of a platinum resistance thermometer due to catalytic oxidations
a measure of the CO2 and H2 content in flue gases. This principle is
used in flue gas analysing equipment.
The CO2 content of exhaust gases is measured using resistance thermometers
enclosed in chambers containing the gases of ariable thermal conductivity. This is also used
for vacuum measurement.
