“A laboratory incubator internal block diagram with a power supply, temperature probe, temperature controller, heating element, circulation fan, incubator chamber, and alarm and display. The power supply feeds the controller, heater and fan; the probe feeds the controller; the controller drives the heater, fan and alarm; and the heater and fan act on the chamber, which returns temperature to the probe.”
看懂背後的決策。
Closes the loop from chamber to probe and controller.
Separates heating from air circulation.
Connects alarms and display to the controller.
Use this view to explain the major parts and temperature-control interfaces of an incubator.
常見問題
Why is the fan included?
It circulates air so the chamber temperature is more uniform.
What closes the temperature-control loop?
The chamber temperature reaches the probe, which feeds the controller that commands the heater.
Is this suitable for a wiring specification?
It is an architecture view; use a wiring diagram for terminals, cables and electrical ratings.
