Versatile Transmitters for a World of Pressure
Proven Technologies
Established in 1972, GE Druck specialises in the
design and manufacture of high performance
pressure sensors for a wide range of applications,
using its own proven micromachined silicon and
related technologies.
GE Druck has its own comprehensive and
technologically advanced silicon processing facility.
Silicon has excellent performance characteristics
and is readily adapted for many applications, from
process and subsea to motorsport and aerospace.
RTX 1000 Flexibility
The RTX 1000 series provides a choice of user
rangeable pressure transmitters with conventional
analogue 4-20mA signal (RTX 1000 A) or with
HART digital signal superimposed (RTX 1000 H).
Offering turndowns up to 100:1 and ranging from
20 mbar to 1400 bar, the RTX 1000 covers the
widest range of gauge and absolute pressure
applications available on the market.
High Performance
The RTX 1000 provides accuracy up to 0.075%
including non-linearity, hysteresis and repeatability
effects. This helps the user to ahieve optimum
process efficiency and ultimate product quality.
Ease of Use
Zero/span pushbuttons and a simple configuration
routine reduce user set-up and calibration time. A
separate terminal on the terminal block allows a
meter to be connected to check calibration
without breaking into the 4-20mA loop.
Low Cost of Ownership
The RTX 1000 offers high value performance and
reliable long term service. For example, 5 year
stability is better than 0.2%, keeping recalibration
checks and process downtime to a minimum.
Media Compatibility
A Hastelloy C276 diaphragm and 316L stainless
steel pressure port are supplied as standard for
compatibility with a wide range of hostile media.
For severe or hygienic process conditions, remote
diaphragm seals can also be supplied.
Harsh Environments
The optional stainless steel electronics housing is
cost-effectivefor applications such as offshore oil
and gas or in hygienic environments such as food
and beverage or pharmaceutical facilities. The
Aluminium Bronze end caps ensure free-running
threads throughout the life of the transmitter.
HARTCommunicator
The Model 275 HART Communicator is the
most widely used communicator on the market.
Supplied with 12MB of memory, it contains the
device descriptions for all HART devices
regardless of manufacturer. It also holds up to 10
transmitter configurations, with optional data
packs available to expand this to 100 devices.
The LCD 8 line x 21 character display simplifies
access to all functions of a HART device. A user
programmable ‘hot’ key allows single key stroke
access to the most frequently used tasks.
Remote Diaphragm Seals
Remote diaphragm seals provide a reliable means
of measuring pressure whilst preventing the
process fluid from directly contacting the
pressure transmitter. A diaphragm seal should
therefore be considered where process
conditions are not directly compatible with the
pressure sensor.
For example, process media which is hostile to
the transmitter wetted materials, contains
suspended solids or is viscous, may corrode or
clog the usual transmitter impulse piping and
pressure connections.
For hygienic applications such as food and
beverage production, a sanitary grade pressure
fitting may be required.
In addition, process temperature which cannot be
brought within the required range (e.g. by use of
impulse piping) may also damage the transmitter
and present a safety risk.
A variety of remote diaphragm seals are available
to meet these and other requirements.
Manifold Valves
A range of 2, 3 and 5 valve manifolds are available
to operate with the transmitters. Manufactured
from 316 stainless steel, these rugged instrument
manifolds are supplied with Teflon gaskets and
high tensile carbon steel bolts where applicable.
Stainless steel colour coded identity tags are
affixed to individual valve head units: Blue for
Isolate, Green for Equalise and Red for Vent
functions. High temperature Grafoil gaskets and
stainless steel bolts are available as an option and
all valves are available compliant with NACE
MR-01-75 for sour gas service if required.
The standard manifold valves are rated up to a
maximum working pressure of 6000 psi (414 bar).
Alternative a high pressure option for service up
to 10,000 psi is available.
