Abstract
Leaks in a steam expansion vessel, such as a flexible curing bladder, may be detected during a high temperature curing cycle by using a humidity sensor in an article curing and leak checking apparatus. The effectiveness of the humidity sensor may be enhanced by selecting or creating a path in the apparatus incorporating the humidity sensor for detecting a leakage of steam, which tends to direct escaping steam to the humidity sensor in a substantially concentrated flow. The humidity sensor may be encased in a portion of the apparatus.
