Chapter 1. INTRODUCTION 1.2 Glossary 1.2.1 A - Analog Value time time [Fig.1.1] Analog Value [Fig.1.2] Digital Value Continuous changeable quantity such as voltage, current, temperature, velocity, pressures and flux is called an analog quantity. For example, temperature changes continuously with time as shown in Fig. 1.1.
Chapter 1. INTRODUCTION 1.2.3 Compensating Wire This means a wire used to compensate error (temperature change) by the distance between terminal of an input thermocouple and input terminal of a thermocouple input module. This has the thermoelectromotive force characteristics between the two terminals under the temperature of 90 to 150 °C or less.
