Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

∫

IEC

IEC integrator element (∫)

The integrator element shows the integral sign inside a rectangular analogue element, usually with an amplifier mark. Its output changes at a rate proportional to the input, so a constant input produces a ramp. Reset or initial-condition inputs may be added to set the starting value.

Form evidence

Rectangular analogue element with integral sign. IEC-style rectangular analogue element presentation; the IEC graphical symbols programme is cited for context only. Independent educational drawing; not certified IEC geometry or an IEC database identifier. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

The differentiator element uses d/dt and responds to rate of change rather than accumulated value.

A distinction that matters

An integrator is an active circuit response; the output range and long-term drift depend on the actual implementation.
