FUNCTIONAL ELEMENTS OF AN INSTRUMENT:
i) Primary sensing element
ii) Variable conversion element &
iii) Data presentation element.
👉Sensing Element: This is the part of the instrument that senses the physical parameter being measured, such as temperature, pressure, or flow.
👉Transducer: This element converts the physical parameter into an electrical signal that can be measured and processed by the instrument.
👉Signal Conditioner: This element processes the electrical signal to remove noise, amplify it, or convert it to a form suitable for further processing.
👉Display: This element provides a visual representation of the measured parameter, such as a numerical value or a graphical display.
👉Recording Element: This element records and stores the measured parameter, either in digital or analog form, for later analysis or comparison.
👉Control Element: This element allows the instrument to control a process or system based on the measured parameter, such as regulating temperature or pressure.
👉Communication Element: This element enables the instrument to communicate with other instruments or systems, either through wired or wireless connections.
👉Power Supply: This element provides the necessary power to operate the instrument, either through batteries or an external power source.
👉Housing: This element provides a protective and functional enclosure for the instrument, ensuring it can be used in a variety of environments.
👉User Interface: This element enables the user to interact with the instrument, either through buttons, knobs, or a touch screen, to set parameters, view results, or perform other functions.
