Abstract
A method of monitoring the status of a plurality of steam traps includes sensing with a monitor at least one process condition in each of a plurality of steam traps, transmitting radio frequency signals responsive to the sensed process condition of each steam trap with transmitters associated with the steam traps, and receiving the signals generated by the transmitters with a receiver. In one embodiment of the invention, the signals from at least some steam traps are received and retransmitted by a repeater positioned between the steam traps and the receiver.
