Abstract
The actual problem of increasing the accuracy of temperature measurement by resistance thermometers has been studied. Existing methods for reducing the errors of these measurements are considered. A method for increasing the accuracy of temperature measurement with a two-wire connection of a resistance thermometer has been studied. An additional error in temperature measurements is due to the resistance of the line connecting the measuring circuit with the resistance thermometer. Reducing the additional error in a two-wire connection is achieved by shunting the resistance thermometer with a capacitor and pulsed power supply to the measuring circuit. The temperature measurement error by the investigated method is comparable to the measurement error using three and four-wire connections. The eff ectiveness of the method is confi rmed by the results of experimental studies on a specially designed stand with author's software. The method can be applied in any industrial temperature control systems.
