A sensor graphic with one threshold line may look clean, but it cannot explain a hysteresis function that uses separate switching and reset points. If that distinction matters to the supplier's account, reserve enough screen time to show the outward and return paths. The output state should remain understandable between them.
ifm's LMC sensor documentation identifies separate set and reset points for its hysteresis functions. Use that as a conceptual example, not a setting recommendation or evidence that another sensor has the same configuration.
Build the explanation around a journey
A trace that rises past one line and later falls past another can make the distinction readable. Give the lines different names rather than relying only on colour. Introduce the measured quantity and output state separately so viewers do not confuse a changing value with a changing switch.
The important moment may be the interval between thresholds, when the value has moved but the illustrated state has not yet changed back. Allow a brief pause there. A fast oscillating animation can hide the very relationship the film is trying to explain.
Use an approved qualitative example unless numerical values are necessary. Arbitrary thresholds can look like recommended settings, particularly when placed beside footage of the actual device.
Keep hysteresis separate from a time delay
A pause in the animation can accidentally imply that the output is waiting for a timer. Explain what the horizontal axis represents and whether the depicted delay is merely presentation pacing. If the client's account includes a separate delay function, give it its own evidence and visual treatment.
The graphic should also distinguish a normal return condition from a fault. Red flashing labels may turn an ordinary state change into an alarm narrative. Ask the client what the states mean before assigning an emotional colour scheme.
Avoid filming a person changing sensor parameters simply to provide action. A case-study explanation can use authorised display footage or an original diagram without becoming a programming tutorial.
A hypothetical edit decision
Suppose a supplier's first cut shows a tank level crossing one line while an output icon repeatedly flickers. The narration mentions hysteresis, but the picture communicates unstable switching around a single threshold.
The buyer replaces the loop with one clear rise-and-fall example using two labelled lines and a separate output indicator. The sequence now explains the approved distinction rather than merely decorating the terminology. This fictional scenario does not prescribe sensor behaviour for a real process.
Ask an unfamiliar viewer what must happen before the output changes back. Their answer should refer to the reset condition, not simply elapsed time or crossing the first line again.
For acceptance, record the represented quantity, state labels and threshold meanings. The client's specialist retains responsibility for actual settings and suitability. The film's role is to make an identified information relationship comprehensible without offering operational advice.
