A steam trap monitoring system that uses radio waves to transmit data is available from Armstrong International, Inc. The radio frequency monitoring system, known as SteamEyeT, gathers instantaneous performance information from up to 2,000 steam traps simultaneously. The system consists of a transmitter that is threaded into the base of an inverted bucket or float, a thermostatic steam trap, a repeater (if necessary), a receiver and a personal computer. The system provides an immediate alert when condensate is backing up.
