1. Insure the mounting hole is clear of any frozen polymer or debris and is machined to the proper
dimensions. Apply a quality high temperature Anti-Seize lubricant to the snout tip threads. For
flanged configuration units, apply Anti-Seize to mounting bolt threads and use proper Buttonseal
gasket and install on transducer snout. Install unit into the process connection. (Do NOT torque
transmitter into the hole at this time!) Allow time for the transmitter snout temperature to
equalize to the process temperature. This will help eliminate thread galling and ease removal
later. There should be NO pressure applied at this time.
2. Connect power to the transmitter. For a 2 wire conduit output configuration, Red wire is Sig+/Exc +,
Black wire is Sig-/Exc-, Green wire is Ground. For a 6 pin connector version, Pin A is Sig+/Exc+ and
pin B is Sig-/Exc-. Insure proper loop supply voltage is applied to transmitter.
3. After temperatures have equalized, apply proper torque as described in Section 5.2 of the Manual
and tighten transmitter into mounting hole.
In hazardous areas do NOT remove screws when circuit is live.
4. Remove zero push-button seal screw.
5. To perform a Zero Calibration, use a 2 mm or smaller allen key and insert into push-button hole to
make contact with push-button at the bottom. Depress the button for 1/2 second, release, then
push again for 1/2 second.
6. Verify loop output is zero (4 mA).
7. Replace the Seal Screw.
Seal screw must remain in place to retain Explosion Proof certification.

The mechanical system (filled assembly) consists of a lower diaphragm, a filled capillary tube, and an
upper diaphragm with a strain gage. The filled assembly transmits pressure from the process to the strain
gage diaphragm where it is converted to an electrical signal. The filled assembly isolates the electronics
from the high process temperatures.
The lower diaphragm is the surface in contact with the media being measured. This diaphragm can be
made from a choice of materials. The standard material is heat-treated 15-5 stainless steel with DymaxTM
coating. This has average corrosion and abrasion resistance and is similar to 17-4 stainless steel. Other
materials are also available including Hastelloy C-276 which has excellent corrosion resistant properties
(but is not good for abrasion). For other materials please consult the factory.
Behind the lower diaphragm is a capillary tube filled to the upper diaphragm. As the process pressure
deflects the lower diaphragm, the fill is displaced through the capillary tube to deflect the upper
diaphragm.

8
GENERAL
The upper diaphragm has a strain gage element in the configuration of a Wheatstone Bridge. The
deflection of the upper 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 lower diaphragm into a usable
electrical signal.

Functioning Principle of the SPX Filled Assembly
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 milliamperes for an output current proportional to the applied pressure.

The SPX series of pressure transmitters can be used in media temperatures up to 400°C. 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 max. +85°C in areas
that are not classified as hazardous.
Higher temperature can result in damage and malfunction. Do not install the pressure transmitter in
places where this temperature is exceeded.

that the complete installation and wiring is intrinsically safe. Care must be taken that the
power source is a certified apparatus.
The SPX series of pressure transmitters is specially designed for measuring pressure in
explosive atmospheres for Zone 0 under safety class II 1 G EEx ia IIC T4 (TA = -20 to + 60°C).
The SPX is also approved for hazardous area Zone 1 under safety class II 2 G
EEx ia IIC T4/T6 (T4, TA = -20 to + 85°C; T6, TA = -20 to + 50°C)
The maximum Tmed (medium temperature) for temperature class T6 is 60°C and for T4 is 85°C. The
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
grounded. If nonmetallic conduits are used they need to be antistatic (< 1G Ohm/cm2).
The SPX series of pressure transmitters are also designed for explosion proof areas
approved by Factory Mutual and CSA for Class I, Division 1, Groups A, B, C & D.
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 safeintrinsically safe
intrinsically safeintrinsically safe
intrinsically safe, EMC compliant power
supply with the following specifications when employing the pressure 4-20 mA output:

13
SAFETY
Supply Voltage max. Uo = 30 V DC
Current Output max. Io = 100 mA
Power max. Po = 0.75W
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
For SPX’s that are not approved or are explosion proof approved for Class I,
Division 1, Groups A, B, C & D the power supply rating is 16-36 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.

N = No Approvals
E = Explosion Proof
S = ATEX/Intrinsically Safe
The SPX series of pressure transmitters are designed for explosion proof areas
approved by Factory Mutual and CSA for Class I, Division 1, Groups A, B, C & D.
The SPX series of pressure transmitters is specially designed for measuring pressure in
explosive atmospheres for Zone 0 under safety class II 1 G EEx ia IIC T4 (TA = -20 to + 60°C).
The SPX is also approved for hazardous area Zone 1 under safety class
II 2 G EEx ia IIC T4/T6 (T4, TA = -20 to + 85°C; T6, TA = -20 to + 50°C)
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 shall be below 5 cm. If metallic conduits are used they need to be
grounded. If nonmetallic conduits are used they need to be antistatic (< 1G Ohm/cm2).
