    摘要: A measurement device for measuring a physical property such as temperature difference, displacement, pressure, fluid flow rate, etc. comprises: (a) an amplifying means which receives and amplifies a voltage signal corresponding to a detected physical property; (b) a reference voltage generator which generates and applies a reference voltage to the amplifying means at a predetermined time; (c) a memory which stores the output voltage signal from the amplifying means when the reference voltage generator applies the reference voltage to the amplifying means; and (d) a calculating means which outputs at least one command signal to the reference voltage generator to apply the reference voltage to the amplifying means and to the memory to store the output voltage of the amplifying means into a specified memory location thereof at the predetermined time and calculates the value of the desired physical property from the current output voltage of the amplifying means with reference to the stored voltage value in the memory, whereby an accurate physical property measurement can be made by compensating for individual differences and deterioration of the characteristics of the measurement device.

    摘要: A device and method for measuring a temperature difference at different positions which cancels offset voltages produced by a temperature sensitive element, e.g., a thermocouple used in the device and the device itself. The device comprises: (a) an amplifier for receiving and amplifying the output signal produced by the temperature sensitive element and output ting a voltage corresponding to a sensed temperature difference; (b) a comparator for determining that the output signal of the temperature sensitive element should be zero level by sensing a condition that the temperature difference between the two different positions is zero; (c) a memory for storing the value of the voltage of the amplifying means outputted when the comparator determines that the output signal of the temperature sensitive element should be at a zero level; and (d) means for subtracting the stored voltage value in the memory from the current output voltage value of the amplifier so as to obtain a modified output voltage value accurately corresponding to the current temperature difference free from offset voltage errors.
