2. General product information
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 a 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
transmitted via 2.4 GHz wireless network to a central PC. The PC determines the trap
condition and calculates any steam loss - See software IMI for commissioning the unit into
operation.
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 stand-
alone 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.
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 head
itself is supplied clamped to the sensor and
connected via 1 m of cable.
The pipe clamp is available in four sizes to
suit the following sized pipelines:
1- ½" - 1¼"
2- 1½"
3 - 2" - 2½" and
4- 3" to 4".
There is also an option with a unique clamp to
secure the head unit to a Spirax Sarco STS17
or STS17.2 pipeline steam trapping station.
The head can be unclamped from the sensor
and refitted remotely (up to 1 m) - See Section
3 for full instructions.
The battery powered head uses a 2.4 GHz
radio to communicate to the receiver.
A head unit can also be configured to act as
a repeater (intelligent head).

Head
An individual trap sensing device which is networkable.
Intelligent Head
A normal head unit which has received additional configuration in order for it to act as a repeater
device. The head will wake up and perform the normal trap analysis functions and then it will
arbitrate to offer a re-transmission service for any other heads which are on the network but
not directly in range of a receiver or repeater.
LAN - Local Area Network
A Local Area Network is a logical group of interconnected devices in a limited geographical
area such as a home, school, factory, or office building.
MAC Address - Media Access Control
A media access control address is a unique number (in the form of six groups of two hexadecimal
digits) that is assigned to a networkable device at the time of manufacture. As the number is
unique it can be used to identify and address particular members of a network.
Network Administrator / IT Administrator (IT Admin)
The network administrator is an individual that is responsible for the maintenance and
monitoring of computer hardware, software systems and related equipment that make up a
computer network. This individual should be able to supply the required advise and details to
install the STAPS system onto your companies network.
Orifice Size
The orifice size is the size of the hole in the trap seat that the condensate passes through.
PAN – Personal Area Network
A collection of co-operative devices sharing a similar geographical location and having a
common PAN-ID.
PAN-ID - Personal area network identification
A PAN-ID is a number allocated to a network co-ordinator (receiver). Heads will base a decision
on which network to join based on their PAN-ID. The default PAN-ID is zero which means that the
device will join any network and then assume the PAN-ID of that network. A device with a non-
zero PAN-ID allocated by the user will only join a network that has the same non-zero PAN-ID.
Receiver
A receiver is a physical device that creates and manages a PAN. It also functions as a gateway
between the PAN and the Ethernet network.
Repeater
A repeater is a physical device not attached to the Ethernet network but forming part of a
PAN. The function of the repeater is to extend the range of the network, where mains power
is available.
RJ45 - Registered Jack 45
RJ45 plugs and sockets along with cat5e cable are used to connect devices together to
form a network. Sometimes called an 8P8C connector. Commonly used on standard LAN
interconnections
