How does the STAPS ISA100 wireless steam trap monitoring system 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 categorized and a steam loss value is calculated and transmitted via an ISA100, 2.4 GHz wireless network to
an ISA100 wireless compliant gateway (Not Supplied).
Each STAPS head unit is powered by a long life Lithium battery (typical battery life of over 3 years).
