I am looking for a word that would accurately describe the period of time between an event is triggered and registered. For an example, an alert is triggered when a threshold is reached, but the alert does not register in the system unless it stays beyond the threshold for a continuous 30 seconds.

Is there a word that defines that 30 seconds? I am thinking countdown but that feels like there are better choices out there.

Thank you.

  • Sounds like "duration".

  • I'd go with 'lapse'.

    It is a 'delay'.

  • latency, or something related to filter. It seems like some sort of low-pass filter. May 14, 2018 at 11:21

In my work I would call it

Processing time

or perhaps simply


For example,

There is a 30 second delay before the system registers an alert. If the signal drops below the threshold during this delay then an alert is not triggered.


I like Tom's answer and am simply adding 'reaction time' which, depending on the circumstances, may be appropriate


Since we are talking about a time frame that was intentionally built in to the system, as opposed to something dictated by the physics of the situation, I'd go with delay threshold when referring to the duration's lower bound. Delays are a common way to mitigate nuisance alarms. The reason you don't get an immediate engine shutdown for low oil pressure when you start a genset or compressor is there is a delay before the shutdown signal is sent. The delay is established to let the oil pressure build up and remove the signal.

Here's a link to a sensor with built-in delay. P28 Series Lube Oil Pressure Cutout Control with Time Delay
