This document is applicable to the production, use, scientific research and teaching of sensors, and serves as the basis for unified technical terminology. 2 Normative References This document has no normative references. 3 Terms and Definitions 3.1 General Classification Terms for Sensors 3.1.1 transducer/sensor device or apparatus that can sense a measurand and convert it into a usable output signal according to a certain rule NOTE 1: A sensor generally consists of a sensing element and a transducing element. NOTE 2: The sensing element is the part of the sensor that directly senses or responds to the measurand. NOTE 3: The transducing element is the part of the sensor that converts the measurand sensed or responded to by the sensing element into an electrical signal suitable for transmission or measurement. NOTE 4: When the output is a specified standard signal, it is called a transmitter. NOTE 5: The slash symbol "/" in the English words indicates that the terms before and after it are interchangeable. 3.1.2 physical transducer/sensor sensor that can sense a specified physical quantity and convert it into a usable output signal 3.1.3 chemical transducer/sensor sensor that can sense a specified chemical quantity and convert it into a usable output signal 3.1.4 biological transducer/sensor sensor that can sense a specified biological quantity and convert it into a usable output signal 3.1.5 intelligent transducer/sensor sensor that has information processing capability, used for transmitting measurement and status information, and receiving and processing external commands 3.1.6 digital transducer/sensor sensor whose output signal is a digital quantity or digital code 3.1.7 analog transducer/sensor sensor whose output signal is an analog quantity 3.1.8 mechanical structure type transducer/sensor sensor that detects the measurand by utilising the deformation of mechanical components (such as metal diaphragms, etc.) 3.1.9 physical property type transducer/sensor sensor that detects the measurand by utilising the physical properties of materials and various physical and chemical effects 3.1.10 quantum transducer/sensor sensor that converts changes in the measurand into usable output signals by utilising quantum effects 3.1.11 discrete transducer/sensor sensor that outputs non-continuous signals 3.1.12 capacitive transducer/sensor sensor that converts changes in the measurand into changes in capacitance 3.1.13 potentiometric transducer/sensor sensor that converts changes in the measurand into changes in voltage ratio by utilising changes in the position of a movable contact on a resistor body 3.1.14 resistive transducer/sensor sensor that converts changes in the measurand into changes in electrical resistance 3.1.15 electromagnetic transducer/sensor sensor that converts the measurand into changes in induced electrical signals in a conductor by utilising changes in magnetic flux 3.1.16 inductive transducer/sensor sensor that converts changes in the measurand into changes in inductance 3.1.17 ionizing transducer/sensor sensor that converts changes in the measurand into changes in ionization current (e.g., ionization current of a gas between two electrodes) 3.1.18 electrochemical transducer/sensor sensor that converts changes in the measurand into changes in potential, current or electrical conductivity by utilising the electrochemical reaction of the measurand 3.1.19 photoconductive transducer/sensor sensor that converts changes in the amount of light incident on a semiconductor material into changes in the resistivity of the material itself 3.1.20 photovoltaic transducer/sensor sensor that converts changes in the amount of light incident on a semiconductor material into changes in photoelectromotive force 3.1.21 opto-electronic transducer/sensor sensor that converts changes in the measurand into usable output signals by utilising the principle of photoelectric conversion 3.1.22 spectrum transducer/sensor sensor that converts the wavelength, wavenumber or frequency of electromagnetic radiation into usable output signals by utilising the principle of spectral response 3.1.23 diffraction transducer/sensor sensor that converts changes in the measurand into usable output signals by utilising the principle of light diffraction 3.1.24 scattering/reflection transducer/sensor sensor that converts changes in the measurand into usable output signals by utilising the principle of light reflection 3.1.25 interference transducer/sensor sensor that converts changes in the measurand into usable output signals by utilising the principle of light interference
