Process Pressure Transmitters
SPX 1000 Series
The SPX 1000 Series scalable pressure transmitter
offers a cost effective solution to gauge and absolute
pressure measurement with outstanding performance.
Any span within a 1:1 to 10:1 ratio of the pressure module upper range limit can be configur ed via a simple setup routine using push-buttons located on the electronics
board. When calibration is complete, a switch locks the
push-buttons out of the main circuit, eliminating this
potential source of drift to ensure optimum long term
stability. The electronics are housed in a compact and
lightweight aluminum alloy housing with an environmental seal between the terminal/ conduit section and
the electronics compartment, thus eliminating failures
due to ingress of condensate. The lightweight design
enables direct mounting to the process, eliminating the
need for additional mounting hardware. An alternate
housing of 316L SS is available with aluminum bronze
end caps. A Hastelloy media isolation diaphragm is fitted as standard enabling the SPX 1000 to be used acr oss
a broad range of industrial applications.
The basic sensor is housed within a high integrity
glass-to-metal seal, providing both electrical and physical isolation from the pressure media. The Hastelloy isolation diaphragm is electron-beam welded to this seal
and transmits applied pressure to the sensor via a silicone fluid filling.
Features
• Ranges from 1 psi to 15,000 psi
• Gauge and absolute pressure ranges
• 10:1 scalability
• Push button zero and span adjustment
• ±0.15% FS accuracy, 400% overpressure
The electronics assembly utilizes microprocessor and
surface-mount technology to create a compact circuit
with the minimum of components. Temperature compensation coefficients are stored within the microprocessor
during manufacture to minimize any errors caused by
changes in ambient temperature. The optional display
module provides local LCD readout.
• Higher performance and lower cost
• Hazardous-area approvals are pending

The transmitter is supplied calibrated in the following
standard ranges or calibrated to any acceptable intermediate span specified. Please discuss your requirements
with an engineer.
0-1 psi to 0-10 psi
0-3 psi to 0-30 psi
0-10 psi to 0-100 psi
0-30 psi to 0-300 psi
0-100 psi to 0-1000 psi
0-300 psi to 0-3000 psi sealed
0-1000 psi to 0-10,000 psi
0-1500 psi to 0-15,000 psi
change for any span down to 10% of the Full Scale (FS),
e.g. a 30 psi device can be adjusted down to a minimum
span of 3 psi (10:1 turndown)
For gauge configuration, the zero (4mA) output of the
transmitter can be set anywhere within the pressure range
-15 psig to +90% FS, e.g. a 30 psig device can be
adjusted to give 4-20mA for -15 to +15 psig. If downranged 10:1 to 3 psig, the 4-20mA can be set anywhere
within the pressure measurement range up to a maximum
zero offset of 27 psi, allowing the calibrated range of 27
to 30 psig
The rated pressure can be exceeded by the following
multiples without degrading performance:
6 x FS for 10 psi range
4 x FS or 2,100 psi maximum, for ranges up to 1000 psi
2 x FS or 13,000 psi max., for ranges up to 10,000 psi
30,000 psi for 15,000 psi range
Application of high pressure up to the following may
damage the sensor but process leakage will not occur:
10x FS for 10 psi range
6x FS (3000 psi maximum) for ranges up to 1000 psi
20,000 psi for absolute and sealed gauge versions 1000
psi and up.
30,000 psi for 15,000 psi range
If installed, the LCD indicator will flash to signify an “out
of range” reading. In the event of a transmitter failure, the
output will be driven to <3.6mA or >21mA (user configurable) and, if installed, the LCD indicator will display
“ALA” to signify alarm state
