Steam trap operation monitoring device

A steam trap operation sensing device comprising:

• steam leakage detector means for measuring and storing data representing the operation of steam traps, and host computer means to which said data are transferred for storing said data, said host computer means operating to record and display the summation of leakage in a plurality of steam traps, the totalization and analysis of leakage in terms of at least one of monetary cost and a rejection rate;
• and changes in each of said steam traps with time, said steam leakage detector means comprising an operation detecting section for sensing parameters of a plurality of steam traps to generate analog signals, an analog-to-digital converter connected to said operation detecting section for converting the analog signals to digital signals, a microcomputer connected to said analog-to-digital converter for receiving the digital signals and for analyzing the digital signals to detect the presence of steam leaks in each steam trap based on the parameters sensed for each steam trap, steam trap reader means for identifying a unique code for each steam trap, said reader means being connected to said microcomputer for correlating the digital signals for each steam trap with a code representing that steam trap, and storage means connected to said microcomputer for storing data concerning the condition and change in condition of each steam trap with regard to steam leakage.
