Heat Flow Experiment

This product is no longer available.

The Quanser Heat Flow Experiment demonstrates control topics related to fluid dynamics and thermodynamics. It introduces a “bump test” method, a simple technique used to find the first-order model of the system and helps students better understand temperature control strategies, such as an on-off control scheme using a relay switch, and advanced PID control topics including set-point weight and integral anti-windup.


Product Details

The Quanser Heat Flow Experiment consists of a fiberglass chamber that is equipped with a coil-based heater and a blower at one end, and three fast settling platinum transducers temperature sensors located equidistantly along the chamber. It has a built-in amplifier to deliver power to the heater and blower. The power delivered to the heater and blower is controlled using analog signals. The fan speed can also be controlled using an analog signal and is measured by a tachometer mounted on the blower measuring angular rate of the blower fan.
