Abstract

An electronic steam trap monitor (402) includes an electric generator (406) configure to couple to a stream trap proximate a potential leak location. The generator (406) generates electricity in response to a process variable from the potential leak location. Communication circuitry (416) provides an output when there is sufficient electricity from the electric generator (406).
