Abstract

PURPOSE:To detect a temperature accurately with a simple construction, by displacing an electrically conductive liquid by the volume depending on the temperature of swelling fluid and intercepting or conducting a pair of electrodes. CONSTITUTION:Swelling fluids 4, 8, such as florinate, having an insulating property which are swelled with a rise in temperature, are enclosed from the temperature detection part 3 of a tubular body 1 to the hollow part 2 commutating to the part 3. Electrically conductive liquids 5, 9, such as mercury, are enclosed in contact with the fluids 4, 8. The fluids 4, 8 are swelled by the rise in temperature and the liquids 5, 9 are lifted and then, electrodes, 6, 7 becomes conductive through the liquid 5, 9.
