Laboratory Incubator Internal Structure
This internal block diagram captures the feedback structure inside a laboratory incubator. A temperature probe measures the chamber and reports to a controller. The controller operates a heating element and circulation fan, both of which affect the chamber, and it drives the alarm and display used by an operator. A power supply serves the active parts. The drawing is a useful starting point for an instrument specification because it separates sensing, control, actuation and the controlled environment. It deliberately does not show wire terminals, heater wattage or firmware details. Add humidity control, a door interlock, a data logger or an independent over-temperature cutoff when those are required by the device.

Scenario
Laboratory instrument design
Key decisions
- Temperature feedback: Closes the loop from chamber to probe and controller.
- Independent actuators: Separates heating from air circulation.
- Operator feedback: Connects alarms and display to the controller.
