ABSTRACT:
A signal device for detecting a faulty steam trap and the like by being responsive to the temperature of steam flow in a pipe. The signal device is a spring wire looped on one end around the pipe and normally connected, at the other end, to the pipe by a metal pellet of low melting point. Upon attainment of a predetermined pipe temperature from steam flow, the pellet will melt and release said wire which spring to a vertical position. The wire carries a signal that can be seen at a distance to denote abnormally high temperature caused by steam flow.
