1.6 TRANSMITTER PRINCIPLES OF OPERATION
The mechanical system consists of a gaged diaphragm. One side of the diaphragm is in direct contact
with the fluid media (gas or liquid) while a strain gage element in the configuration of a Wheatstone
bridge is bonded to the backside.
The deflection of the diaphragm causes a change in the resistance of the strain gage and hence a change
in the balance of the bridge. The amount of imbalance is directly proportional to the applied pressure.
This completes the translation of pressure applied to the diaphragm into a usable electrical signal.
The low level output signal from the bridge is amplified via an instrumentation amp circuit. The
amplified signal then goes to the input of the analog-to-digital (A/D) converter.
Once the microprocessor has the converted voltage input from the A/D converter, the digital signal is
sent to a digital-to-analog (D/A) converter which modulates the current of the unit’s power supply
between 4 and 20 mA for an output current proportional to the applied pressure.

2 NOTES ON SAFETY
he operator or owner of the larger overall system is responsible for following the safety and accident
T
prevention regulations that apply to the specific application.
DYNISCO will not be held liable for any injury, loss or damage resulting from failure to follow the
instructions in this manual.
Warnings
The SPX is an ESD sensitive component. Electrostatic discharge may damage the SPX. Take ESD
precautions.
Electrical shock can result in death or serious injury. Avoid contact with the leads and terminals. High
voltage that may be present on leads can cause electrical shock.
Mounting and electrical connection of the PT must be done by specialists with EMC training, following
all applicable regulations, and in pressure-less, voltage-free, intrinsically safe condition with the
machine switched off. The machine must be secured against being switched back on!
EMC/CE Compliant Connection
Earth the machine section with the process connections for the SPX in accordance with regulations. The
SPX must be connected to earth via the process connection.
Connect the shield of the connecting cable on both sides, making sure it conducts with full and
continuous contact.
When introducing the connecting cable into an EMC compliant switch cabinet, for example, connect the
shield correctly (cable gland, conducting, full contact, and continuous) to the conductive housing or
route it via a built-in cable connector that is also connected to the conductive housing. Connect unused
cable cores or free cable ends correctly to the cable shield on both sides.

-12-
Temperature
The SPX can be used in me
dia temperatures up to +85°C (based on configuration). If the pressure
transmitter is used in other applications, the safety and accident prevention regulations specific to that
application must be followed. Ambient temperature for the electronics housing is +85°C maximum in
areas that are not classified as hazardous.
Higher temperatures can result in damage and malfunction. Do not install the pressure transmitter in
places where these temperatures are exceeded.
Use in Hazardous Classified Areas
Se
veral configurations of the SPX are designed and approved for use in hazardous classified areas. Units
intended for installation in these areas must bear the applicable approval agency label.
The SPX is specially designed for measuring pressure in explosive gas atmospheres for Zone 0 under
safety class II 1 G Ex ia IIC T6/T4 (T6, Ta = -20 to + 50°C; T4, Ta = -20 to + 85°C). The SPX is also approved
for hazardous gas area Zone 1 under safety class II 2 G Ex ia IIC T6/T4 (T6, Ta = -20 to + 60°C; T4, Ta = -20
to + 85°C).
The maximum T
(medium temperature) for temperature class T6 is +60°C and for T4 is +85°C. The
med
medium temperature for the SPX is defined as the temperature of the pressure transmission fluid below
the measuring diaphragm (See Figure 1-1). This temperature can be verified by measuring the surface
temperature at the base of the electronics housing.
For category 1 (Zone 0) installations, care must be taken to avoid the danger of ignition due to
electrostatic discharges (ESD). The chance for static build up on the cable surface during normal
conditions of use, maintenance and cleaning must be eliminated. Install the cable in an appropriate
conduit or use some other cable reliable installation technique to avoid static electricity at the cable
surface.
The free length of the cable must be below 5 cm. If metallic conduits are used they need to be
g
rounded. If nonmetallic conduits are used they need to be antistatic (< 1G Ohm/cm
2
).
The housing shall be connected reliably to the local equipotential bonding system.
Those variants that include the material aluminum shall be installed in such a way that sparking as a
sult of impact or friction between aluminum and steel is excluded. Impact or friction between
re
aluminum and stainless steel is allowed if the existence of rust particles can be excluded.
For application as Category-1-E
conductive coating (R
surface < 10
quipment the connecting cable shall be equipped with a suitable
9
Ω) to avoid possible electrostatic charge.
After installation before operating the device the user must check that the complete
installation and wiring is intrinsically safe. Care must be taken that the power source is a
certified apparatus.

Deviation of the supply voltage from the value given in the technical specifications, or reverse polarity,
can damage the pressure transmitter and cause malfunctions that can pose a risk of explosion. Operate
only with an intrinsically safe, EMC compliant power supply with the following specifications when
employing the pressure 4-20 mA output:
Supply Voltage max. Uo = 30 V
DC Current Output max. Io = 100 mA
Power max. Po = 0.750 W
The specified values of Lo and Co for the power supply need to be greater than Ci + Ccable and Li +
Lcable.
Internal Inductance Li < 40 µH
Internal Capacitance Ci < 4.5 nF
If the transmitter is installed in hazardous areas, only passive devices like switches or resistors may be
connected between the RCAL+ and RCAL- signals. Connection of any active electronic circuits or voltage
or current sources is not allowed.
Certain configurations of the SPX are also designed for use in hazardous areas as Explosion-proof and
Dust Ignition-proof by Factory Mutual for Class I, Division 1, Groups A, B, C & D, and Class II, III, Division
1, Groups E, F & G.
For SPX units that are explosion-proof approved for Class I, Division 1, Groups A, B, C & D the power
supply rating is 13-30 Vdc.
Additional Comments:
1) Do not remove the transmitter push-button seal screws in explosive environments when the circuit
is live.
2) Transmitter push-button seal screws must be fully engaged to meet Explosion-proof requirements.
3) Before connecting a HART handheld communicator in an explosive atmosphere, make sure the
instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring
practices.

2.1 SAFETY integrity and performance level applications
User’s obligations
The operator or owner of the larger overall system, e.g. a machine, is responsible for following the
safety and accident prevention regulations that apply to the specific application.
Intended Use
See Certificate in section 9.4
Safety Function
See Certificate in section 9.4
For units with the optional monitoring channel (Guardian Series, Option Code = GCxxx):
Under normal operating conditions the relay contacts are closed. In the event that a failure is detected
the relay contacts open. Detectable failures include:
1) Loss of Power
2) Open Gage
3) Input over a predefined (customer selectable at time of order) threshold
The Guardian Series transducer has been designed to provide a protective measure. This has been done
by the avoidance and control of systematic and random failures.
This product will:
Measure the pressure and provide a safety relay output. Since this is being used to perform a protective
measure, this sensor should only be used for monitoring the pressure and not controlling the process.
Best practices declare that safety and control must be independent from each other.
The Guardian Series transducer detects many hardware failures including an open or short in the
measuring gage and if there is an overpressure condition. If any of these failures occur, the output relay
will open. It is the user’s responsibility to connect this relay to the system in such a way that when this
relay opens, it brings the system to a safe state.

This fault state is not latched. It is up to the user to latch this error if desired.
Recommended practices
This Guardian Series transducer must be installed in such a way that the opening of the
output relay will bring the system to a safe state. In this safe state the instrument that is
monitoring the pressure should be left operational.
This error indication is not latched. If it is necessary to latch the error until it is manually
reset, this is the user’s responsibility.
At startup and on a periodic basis the safety system should be tested to ensure proper
operation. This will require applying a pressure to the Guardian Series transducer that is
over the safe level but less than the maximum pressure. Verify that the protective measure
is initiated to take the machine to a safe operating condition.
Use of qualified personnel
The product may only be assembled, installed, configured, commissioned, operated and
maintained by persons with proven skills. Persons with proven skills are suitably
experienced to operate devices, systems, plant and machinery in accordance with the
general standards and guidelines for safety technology.
It is the user’s responsibility only to employ personnel who:
• Are familiar with the basic regulations concerning health and safety and accident prevention
• Have read and understood the safety guidelines given in this description
• Have a good knowledge of the generic and specialist s ta nd a rds applicable to the specific application
