2.1 General description
The STAPS wireless steam trap monitoring system has been designed to efficiently monitor and evaluate
steam trap operation. It surveys the operation of the steam trap at regular intervals and identifies poor
performance that can cause reduced plant efficiency and increased energy consumption. It can diagnose
both failed-open steam traps that leak live steam, and those that have failed-closed or are blocked, resulting
in waterlogging, leading to plant damage, product spoilage and health and safety concerns.
Using non-intrusive installation technology combined with ISA100.11a 2.4 GHz wireless network, it is an
ideal solution for steam trap monitoring. It is suitable for use with all types of steam trap and can be connected
to pipework up to 100 mm (4"), via an adjustable clamp.
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 the trap
condition and steam loss are transmitted via 2.4 GHz (ISA100.11a)
wireless network. The trap condition and steam loss data is
available via the ISA100.11a network.
Each STAPS head unit assembly is powered by a long life
Lithium battery (typical battery life of over 3 years). The device
is ISA100.11a compliant, and is capable of seamlessly joining
and being part of existing and new ISA100.11a compliant
networks. It is capable of acting as an ISA100.11a routing device
if and when required to extend the radius of the network, but
this will have an effect on the expected lifetime of the battery.
To maximise battery lifetime, the device should be set to act
as an ISA100.11a I/0 (end node) only device with the routing
functionality turned off.
The steam trap data of each device is passed over to the
ISA100.11a network Manager via a backbone router (Access
Point), and is made available to the backbone network via
interface(s) of the ISA100.11a network Gateway.
2.2 STAPS head unit assembly
The STAPS head unit includes the head unit and the sensor and
clamp that must be connected to the steam pipe upstream of the
steam trap that it is monitoring. The pipe clamp is available in
four sizes to suit: ½" - 1¼", 1½", 2" - 2½" and 3" - 4".
