To prevent misapplication, pressure gauges should be selected considering media and ambient operating conditions.
Improper application can be detrimental to the gauge, causing failure and possible personal injury, property damage or
death. The following information is offered as a guide in making the proper selection of a pressure gauge. Additional
information is available from Ashcroft. The following highlights some of the more important considerations:
1.1 Range – The range of the instrument should be approximately twice the maximum operating pressure. Too low a
range may result in (a) low fatigue life of the elastic element due to high operating stress and (b) susceptibility to
overpressure set due to pressure transients that exceed the normal operating pressure. Too high a range may yield
insufficient resolution for the application.
1.2 Temperature – Ideally, pressure gauges are used at an ambient temperature between –20 and +150F (30 to +65C).
At very low temperatures, standard gauges may exhibit slow pointer response. Above 150F, the accuracy will be
affected by approximately 1.5% per 100F. Duralife gauges types 1008 and 1009, can withstand continuous operating
temperatures up to 250F.
1.2.1 Accuracy – Heat and cold affect accuracy of indication. A general rule of thumb for dry gauges is 0.5% of full
scale change for every 40°F change from 75°F. Double that allowance for gauges with hermetically sealed or liquid
filled cases, except for Duragauge® gauges where no extra allowance is required due to the elastomeric, compensating
back. Above 250°F there may exist very significant errors in indication.
1.2.2 Steam service – In order to prevent live steam from entering the Bourdon tube, a siphon filled with water should
be installed between the gauge and the process line. Siphons can be supplied with ratings up to 4,000 psi. If freezing of
the condensate in the loop of the siphon is a possibility, a diaphragm seal should be used to isolate the gauge from the
process steam. Siphons should also be used whenever condensing, hot vapors (not just steam) are present. Super heated
steam should have enough piping or capillary line ahead of the siphon to maintain liquid water in the siphon loop.
1.2.3 Hot or very cold media – A five foot capillary line assembly will bring most hot or cold process media within
the recommended gauge ambient temperature range. For media above 750F (400C) the customer should use his own
small diameter piping to avoid possible corrosion of the stainless steel. The five-foot capillary will protect the gauges
used on the common cryogenic (less than –300F (200C) gases, liquid argon, nitrogen, and oxygen. The capillary and
gauge must be cleaned for oxygen service. The media must not be corrosive to stainless steel, and must not plug the
small bore of the capillary.
1.3 Media – The material of the process-sensing element must be compatible with the process media. Consult the
Corrosion Guide available on the website:www.ashcroft.com. Use of a diaphragm seal with the gauge is recommended
for process media that (a) are corrosive to the process sensing element; (b) contain heavy particulate (slurries) or (c) are
very viscous including those that harden at room temperature.
1.4 Oxidizing media – Gauges for direct use on oxidizing media should be specially cleaned. Gauges for oxygen
service should be ordered to variation X6B and will carry the ASME required dial marking “USE NO OIL” in red
letters.
1.5 Pulsation/Vibration – Pressure pulsation can be dampened by several mechanisms; the patented PLUS!
Performance gauge will handle the vast majority of applications. One exception to this is high frequency pulsation that
is difficult to detect. The only indication may be an upscale zero shift due to movement wear. These applications
should be addressed with a liquid filled gauge, or in extreme cases, a remotely mounted liquid filled gauge connected
with a length of capillary line.
1.6 Gauge fills. – Once it has been determined that a liquid filled gauge is in order, the next step is selecting the type of
fill. Glycerin is suitable for temperature ranges of 20/250°F. Silicone filled gauges have a broader service range: –
40/250°F. Oxidizing media require the use of Halocarbon,
The WX-1 provides pressure measurement data from numerous clustered measurement points, via radio, in

1.2 ART-5209 Router
A router is used to extend the coverage area of the wireless gauge network by passing the communication
though one or more routers in a wireless network. In order to achieve this capability the router must always
be powered. This requires that the router be mains powered. The router can communicate up to 30 meters
or more to a gateway or another router and 20 meters to a wireless gauge transmitter. Routers can be used
to increase the distance between a wireless gauge transmitter and gateway, extending the span of the
network to thousands of meters. Routers are also used to improve the integrity of communication networks
that show significant problems with channel coherence or interference by providing alternate (mesh)
communication paths from measurement to gate way . Wi reless communication networks consisting of o nly
XW-1wireless pressure gauges can only form a star topology, as the XW-1 wireless pressure gauges cannot
communicate between each other but only to the gateway.
1.3 AGW-5209 Gateway
The gateway allows network monitoring and control. It serves as the focal point of the network. It
aggregates data traffic from endpoint transmitters and routers within radio range, and communicates to a
host computer. The gateway also relays commands from the host computer to routers and endpoint
transmitters and supervises the operation of the network.
Ashcroft’s innovative, self-organizing network technology combines battery-powered WX1 wireless
pressure gauges and ART-5209 routers and an AWG-5209 Gateways to form a reliable, scalable star-mesh
wireless network (see Figure 1-1). This is a unique solution for low data-rate networks that provides both
long battery life at the pressure sensor interfaces and fault-tolerant networking. The network protocol
creates robust, fully redundant wireless links from the AWG-5209 Gateway to the WX1 wireless pressure
gauge through a self-configuring mesh network.

Each network device is configured at the factory with a unique device ID and a gr oup ID. The device ID
identifies the device within a network, while the group ID identifies the WX1 network that the device is
associated with. The group ID allows the system to establish multiple networks within the same location
without interfering with each other. Devices (WX1 wireless gauges and ART-5209 routers) can join a
specific network only if they have the same group ID that is assigned to the AWG-5209 Gateway. Both
group and device IDs are statically assigned and cannot be changed by a system user. The network
elements self-organize at power-up and re-configure in response to changes in the environment network
traffic, device status, and location. This enables mobility and minimizes installation and operating costs.
inductance sensor, microcomputer, and a wireless transceiver
XmitrTM
ART-5209 Routers extend network coverage area, routes around obstacles, and provides back-up
routes in case of network congestion or device failure.
AGW-5209 Gateways interface the XW-1 network to your host PC. They aggregate data from the
network and act as a portal to monitor performance and configure network parameters. AGW5209 Gateways connect via an RS-232 connection to the ho st PC, which in turn could be
connected to a LAN or the Internet through one or more physical-layer interfaces, including RS232, Ethernet, 802.11, landline or cellular modem. XW-1 wireless pressure gauges, ART-5209
Routers, and AGW-5209 Gateways self-organize at power-up and quickly re-configure as devices
join, leave, or move around the network. They also adapt to changes in network traffic and
propagation conditions. These capabilities enable mobility o f individual devices or the entire
network, and minimize installation and operating costs.
The following procedures describe in order, ho w t o install the hardware components of the WX1 Wireless
pressure measurement system. When initially setting up the hardware, it is recommended that AGW-5209
Gateway, ART-5209 Routers, and WX-1 wireless pressure gauge be placed close to the host PC. This will
make verifying proper network installation and operation easier when first establishing a session with A5209 Network Monitor. The devices can then be moved away from the host PC to their ultimate locations.

the installation process. A special prompt screen is then displayed, allowing you to modify, repair, or
remove the existing files. You must select Remove to uninstall the exiting version before installing the
version contained on the CD.
3.4.2 Launching AM-5209 Network Monitor using Windows
Using the standard application launching methods of Windows, the following procedure describes how to
launch AM -5209 Network Monitor and verify proper communication with the XW-1 network nodes (see
Figure 2-5):
1. To launch AM-5209 Network Monitor, do one of the following:
– Double-click on the desktop’s AM-5209 Network Monitor icon.
– From the Windows taskbar, select:
The AB-5209 Network Monitor is a monitoring and management system for AB-5209 networks. This
management tool will discover and display active Routers in the vicinity of the Gateway, and XW-1
Endpoints in the range of the Gateway and Routers as shown in Figure 3-1. AB-5209 Network Monitor
displays the Group ID and Device ID of the Gateway and will display only XW-1 gauges and Routers that
have the same Group ID as the Gateway. (For information on opening a AB-5209 Network Monitor
session, see ’Launching AB-5209 Netw o rk M oni t o r usi ng Windows’ on page PP.)
Using AB-5209 Network Monitor, a number of the monitoring features may be observed:
• Any of the XW-1s can be moved, and as long as they are within the range of a Router or the Gateway, connectivity will be maintained seamlessly. Any of the Routers and even the Gateway can be
moved while operating, and all routes will automatically adapt to their new locations.
• The network routing protocol always seeks to route data using the most reliable RF links with the fewest hops. The network protocol will change the route when an RF link in the route is deemed
unreliable. This can be seen in the AB-5209 Network Monitor. For example, the Router IDs used for the
first and last hops may change from time to time even when the XW-1 is stationary, due to environmental
interference.
• If any of the Routers runs out of battery power or is turned off, all routes that went thr ou gh th at
Router will be reconfigured—all XW-1s communicating with that Router will still be connected to
other Routers without any disruption or loss of packets. However, if a XW-1 exceeds the range of the
network due to the loss of a Router, then the XW-1 will be displayed as Offline or removed from the
display (depending on how the Persistence function is configured).
