Abstract

PURPOSE:To countervail the zero drift of a temperature difference and to improve precision, by a method wherein temperature measuring resistors are individually mounted at an inlet and an outlet of a device in which fluid, such as water, is used as a thermal medium, and a constant-current circuit and an amplifier are commonly used for temperature measurement at an inlet side and an outlet side. CONSTITUTION:In an integrating calorimeter, a constant-current circuit 5 and sample hold circuits 11, 12 are mounted. The constant-current circuit 5 is connected through analogue switches 3 and 4, acting as an ON, OFF switch, to an inlet temperature measuring resistor 1 and an outlet temperature measuring resistor 2 that are positioned in parallel to an inlet and an outlet of a device wherein fluid, such as water, is used as a medium. The sample hold circuits 11 and 12 conduct operations to sample and hold electric potentials V1 and V2, generated at the inlet temperature measuring resistor 1 and the outlet temperature measuring resistor 2, through analogue switches 6 and 7, acting as the ON, OFF swtich, and an amplifier 8. The constant-current circuit 5 and the amplifier 8 are commonly used for measuring a temperature at an inlet side and an outlet side, whereby this permits countervailing of the zero drift of temperature difference and enables to perform a high-stable and high-precise measurement.
