A major application of current loops is the industry de facto standard 4–20 mA current loop for process control applications, where they are extensively used to carry signals from process instrumentation to proportional–integral–derivative (PID) controllers, supervisory control and data acquisition (SCADA) systems, and programmable logic ...
The scale current is proportional to the cross-sectional area of the diode. Continuing with the symbols: V T {\displaystyle V_{\text{T}}} is the thermal voltage ( k T / q {\displaystyle kT/q} , about 26 mV at normal temperatures), and n {\displaystyle n} is known as the diode ideality factor (for silicon diodes n {\displaystyle n} is ...
This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...
The logarithmic scale used for the bottom plot is useful for expressing the equation's exponential relationship. The Shockley diode equation , or the diode law , named after transistor co-inventor William Shockley of Bell Labs , models the exponential current–voltage (I–V) relationship of semiconductor diodes in moderate constant current ...
The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD).. As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.
