Proven reliability
- What is the cost of
downtime in your plant?
- Proven reliability you
would expect from Emerson
- Fully integrated
accessories eliminate common failure points
- Predictive diagnostics
prevent unplanned downtime
-
Plug-and-play functionality enables speedy repair and
upgrades
Based on proven technology – with an installed base of over
two million units – and designed for superior and safe
performance over time, FieldQ has been subjected to over 1
million open/close cycles. The balanced pinion design uses
seals with low surface pressure and low wear, effectively
reducing the maintenance requirements.
The large
diaphragm poppet design ensures reliable opening and
closing, even at sub-zero temperatures where moisture in the
air has the potential to freeze and block other pilot valve
designs. The revolutionary design enables the use of a low
power pilot valve, while still maintaining a fast response
time.

 Corrosion
resistance increases service life
An integrated breather function provides protection of
the actuator spring chamber from any corrosive elements
in the atmosphere being sucked into the actuator during
the return stroke, preventing spring corrosion. Anodized
internals and a corrosion resistant polyester powder
coat finish ensure long-term reliability in aggressive
atmospheres, exceeding a 1000 hour salt spray test (ASTM
B117).
Many failures are caused
by external damage. By housing all the controls
internally within the robust FieldQ unit, no vulnerable
parts are exposed. The enclosure is rated to IP65 and
NEMA 4X, while variations for hazardous areas are
available that are certified to meet ATEX, CSA and FM
requirements.
For easy installation and
commissioning, the Control Module can be pre-wired to
provide a quick connection. FOUNDATION Fieldbus™ modules
can be initialized digitally by the bus system. Together
with quick connectors this eliminates the requirement to
open the Control Module for wiring and initializing.
This also saves time ensuring that the Control Module
interior is kept clean.

Predictive
diagnostics minimize downtime
The process
industry is facing demands for improved safety, plant
availability and process control. This is driving the
need for more and better process information. Accurate
and timely information is key to addressing these
challenges yet few pneumatic rack and pinion actuators
are capable of providing the enhanced diagnostic
information needed. FieldQ is just the latest of
Emerson’s intelligent field devices that are key
elements of PlantWeb digital plant architecture. FieldQ
offers exciting possibilities for device diagnostics via
FOUNDATION Fieldbus™ and Profibus, in addition to the
more basic functions offered by AS-i. bus
As downtime is very
expensive (costs could exceed $100,000 per hour for a
chemical or pharmaceutical plant), Emerson recognizes
the need to keep plants running for as long as possible
and the important role that predictive maintenance plays
to achieve that goal. Diagnostics information is
essential in enabling this move towards predictive
maintenance.
Imagine the benefit to
you in knowing “in advance” when a final control element
will be in need of repair and, if it does need repair,
what will need to be repaired. Running diagnostics on
valves equipped with FieldQ Pneumatic Valve Actuators
enables you to make sound, predictive maintenance
decisions. |

 Alerts
provide immediate feedback
Diagnostic alerts can
signal implied or actual problems with the final control
element. These alerts can be continuously scanned,
providing immediate feedback to operations while the
valve is still controlling the process.
FieldQ powers PlantWeb®
by capturing diagnostic data from all the components of
the final control element and delivering it to the easy
to use interface of AMS Suite: Intelligent Device
Manager software. This enables the user to configure,
calibrate, monitor, perform diagnostics and maintain
records for virtually any FieldQ equipped valve in the
plant, all from a single central location. Diagnostics
provided include:
- Travel times
- Cycle counts
- Time in position
- Various internal
electronic health tests
- Module temperature
- PlantWeb® Alerts
The FieldQ pneumatic
valve actuator has been tested by the Fieldbus
FOUNDATION and is registered as having passed the latest
interoperability test of the FOUNDATION. FieldQ contains
one Discrete Output (DO), two Discrete Input (DI) and
two Analogue Input (AI) for ON-OFF applications. The
function blocks can be assigned to various parameters
including position, temperature, and control, to name a
few. |

Cost-effective maintenance
The compact modular design of FieldQ comes into its own
if maintenance is required. If a Control Module, or one
of the accessories fails the plug-and-play functionality
enables a quick change out. In addition, upgrades -such
as a change to the communications protocol, or backwards
integration by adding Namur solenoid valves or switches
– can be easily undertaken by changing or adding
modules. |
