GOOD THERMOSTATIC STEAM TRAP TIME SERIES VIEW
This trap will operate in an "open-close" cycle. As steam enters, the thermostatic element expands and the trap will close. When the steam cools to condensate, the element will contract and open. The number of cycles and the time between cycles is dependent on the condensate load. It can discharge for long cycles or stay shut for a long time. Conversely it can also open and close rapidly..

THERMOSTATIC STEAM TRAP STUCK OPEN TIME SERIES VIEW
Should the thermostatic element fail, the trap can be stuck open. Acoustically the "open-close" pattern disappears and only a steady rushing sound of steam blowing through will be heard.
