Advanced Transmitter
Gauge Pressure Transmitters
Model GTX60G/GTX71G/GTX82G
OVERVIEW
Advanced Transmitter is a microprocessor-based smart
transmitter that features high performance and excellent
stability. Capable of measuring gas, liquid, vapor, and liquid
levels, it transmits 4 to 20 mA DC analog and digital signals
according to the measured pressure.
It can also execute two-way communications between thecommunicator, thus facilitating self-diagnosis, range resetting, and automatic zero/span adjustment.
SFN, HART and FOUNDATION Fieldbus are available.
* Refer to SS2-GTX00Z-0100 for FOUNDATION Fieldbus type
for the items marked with [].

FEATURESHigh performance and stability

Remote communication• Unique characterization and composite semiconductor
sensors realize high accuracy up to 0.04 % F.S.

• Two-way communication using digital output facilitates
self-diagnosis, range resetting, automatic zero adjustment,
and other operations.

• Our proven sensor technology enables Long-term stability
up to 0.1 % of URL per 10-year.

Wide measuring range (range ability)• A wide measuring range is available from a single model.
This feature is highly effective in taking measurement overa wide range and reducing the need for inventory.
• Model GTX60G: 17.5 to 3500 kPa (range ability: 200 to 1)

A diverse lineup• A wide range of models is available to meet user requirements for low, standard, and high pressures.
• A wide variety of corrosion-resistant materials for wettedparts is also available.

Specifications are subject to change without notice.

TRANSMITTER HANDLING NOTES

Handling precautions for HART
specification devices

To get the most from the performance this transmitter canoffer, please use it properly noting the points mentioned
below. Before using it, please read the Instruction Manual.

• If you need to operate with a secondary host (HART
communicator, etc.), set the communication interval of
the primary host (DCS, device management system) to
8 seconds or more, or suspend communication from theprimary host. If the primary host repeats HART communication within 8 seconds, the request from the secondary
host may not be received (communication may not be
possible).

Transmitter installation notes
WARNING• When installing the transmitter, ensure that gaskets do not protrude from connecting points into the process (such as adapter
flange connection points and connecting pipes and flanges).
Failure to do so may cause a leak of process fluid, resulting inharm from burns, etc. In addition, if the process fluid contains
toxic substances, take safety measures such as wearing goggles
and a mask to prevent contact with the skin and eyes and toprevent inhalation.

• If electrical noise in the environment prevents HARTcommunications with the host, take countermeasures such as
separating the signal cables from the source of the noise,
improving the grounding, changing to shielded signal
cables, etc. Even if noise interferes with HART communications, the 4–20 mA analog signal will be unaffected andcan be used for control.

• Use the transmitter within the operating ranges stated in
the specifications (for explosion-proofing, pressure rating,temperature, humidity, voltage, vibration, shock, mounting
direction, atmosphere, etc.). Using the transmitter outside theoperating conditions may cause device failure or fire, resulting
in a harmful physical risk of burning or the like.

• If this product is being operated in multidrop mode, there
is a limit to the number of devices that can be used. If you
are using multidrop mode, please consult with us.

• When performing wiring work in explosion-proof areas, follow
the work method specified in the explosion-proof guidelines.

CAUTION• After installation, do not use the transmitter as a foothold or
put your weight on it. Doing so may cause damage.
• Be careful not to hit the glass indicator with tools etc. This
could break the glass and cause injury.
• The transmitter is heavy. Wear safety shoes and take care when
installing it.
• Impact to transmitter can damage sensor module.

Wiring notes
WARNING• To avoid shocks, do not perform electrical wiring work with
wet hands or with live wires.

CAUTION• Do wiring work properly in conformance with the specifications. Wiring mistakes may result in malfunction or irreparable
damage to the instrument.
• Use a power supply that conforms to the specifications. Useof an improper power supply may result in malfunction or
irreparable damage to the instrument.
• Use a power supply with overcurrent protection for this instrument.
