Steam traps Steam trap management
8
How does it work? A head unit assembly mounted on the pipe upstream of the trap to be monitored 'listens' to the sound signature of the trap in operation. This sound signature is categorised and transmitted via 2.4 GHz wireless network to a central PC. The PC determines the trap condition and calculates any steam loss. Each STAPS head unit assembly is powered by a long life Lithium battery (typical battery life of over 3 years). It can communicate directly to a receiver that is connected to the PC software via a LAN connection or via another intelligent head or repeater. The PC software can be installed onto a PC on the sites internal network, or onto a standalone local PC. The STAPS head, repeater and receiver create a network and can communicate with each other, passing on the steam trap data to the supervisory PC. The illustration below illustrates a typical network.
