Thermal-Cycle Testing
400°F Heat Up at 932°
At 932°F continuous surface contact temp, it takes over 9 minutes for the sensitive solder joints within the transducer to get to 400°F.
33% Duty Cycle
This chart shows a 33% duty cycle at 5 seconds on and 10 seconds off. The DHT-400 plateaus at ~270°F which keeps the sensitive elements rom ever reaching 400°F. At a 50% duty cycle of 10 seconds, the DHT-400’s sensitive elements never get to 400°F.
