Technical data

The widest workload coverage in an automatedpressure controller

The 8270A and 8370A areautomated pneumatic pressure
controllers that calibrate a wide
workload of pressure sensors,
covering twice the pressure
ranges at twice the speed ofother high-pressure controllers.
Two models let you balance
price and performance:• The 8270A measures and controls pressures from vacuum to
44 MPa (6400 psi). It can be
configured with ranges as low
as 100 kPa (15 psi).
• The 8370A measures andcontrols pressures fromatmosphere to 107 MPa(15,500 psi). It can be configured with ranges as low as
700 kPa (100 psi).

100:1 control turndown
A pressure range 100 times
smaller than the full scale willmeet the control specifications
without reducing supply pressure. For example, an 8370A
with a 70 MPa (10,000 psi)
high range module and a
700 kPa (100 psi) low range
module will be able to control
pressures below 700 kPa(100 psi) to within ±0.014 kPa(0.002 psi) without reducing the
supply pressure.

Flexible configuration
options

The 8270A and 8370A are
modular systems that can be
configured with up to fivemeasurement modules at the
Fluke Calibration’s uniquesame time, so they can handle
control technology enables you
to use these calibrators at low or high pressure, low pressure, andeverything in between. Threehigh pressures, all in the samefamilies of modules provide
instrument. Control precision isthree levels of performance that

by using the optional Contamination Prevention System (CPS).

flexibility in configuration.

Calibrate without risk ofcontamination
The 8270A and 8370A, coupledwith the optional CPS, cancalibrate both gas-filled andliquid-filled devices without concern of contamination.
With its wide pressure range
coverage, one controller canaccomplish the task that used torequire two separate standards.

Modern replacements forhydraulic deadweighttesters and comparators
Safety: the number one
priority
Safety is the top priority inthe design and manufacture of
our pressure products, especially high-pressure pneumatic
controllers. The 8270A and8370A meet all appropriate
safety standards. Each unit isequipped with over-pressure
protection as well as a frontpanel abort button. Pressing
the abort button vents the test
pressure and returns the unit toa safe condition. Additionally,an abort valve accessory allows
for faster, directed vent, as well
as automated venting at loss of
power. High-pressure gas does
have more stored energy thanhigh-pressure oil, but it is a safe
option under the right conditions. By using the 8270A or
8370A with the available accessories, you have safe operation
with a clean pressure media.

2 Fluke Calibration

Easiest to use high-pressure
standards available
Automated pressure controllers
are some of the simplest, easiest-to-use pressure standards.
Controlling and measuring pressure is as simple as typing in therequired pressure and pressing Enter. Unlike deadweighttesters, you do not need to spinweights at a particular speed or
calculate gravity or temperaturecorrections. Unlike pressurecomparators, the process can be
fully automated and stability isachieved and maintained in a
fraction of the time.

Flexibility to handle a wide
variety of applications andworkloads
The 8270A and 8370A can be
configured with different classesof modules with different pressure ranges. This gives you
flexibility to handle a variety
of applications and workloads.
Uncertainties as good as
0.01 % reading are available
across the vast majority of
the range, making it an ideal
replacement for deadweighttesters.

8270A and 8370A Modular Pressure Controllers/Calibrators• Onboard barometer included withabsolute mode modules, allowing them tobe used in both absolute and gauge mode

An affordable solution thatcan grow as your requirements doWith their wide pressure range
coverage, the 8270A and 8370A
can replace multiple standards
at once. Thanks to the modular
design, pressure ranges andcapabilities can be added at any
time, allowing for lower cost ofentry in favor of future expansion, growing with your needs.

Ideal for characterizationor calibration in production
lines
Whether you manufacture large
batches of low cost pressure
sensors or customized, expensive
pressure sensors for aerospaceand other mission critical applications, the 8270A and 8370A
are ideal for use in your production line.

Robust design provides
unsurpassed control
performance
The 8270A and 8370A make useof our unique pressure control
technology, first developed tohandle some of the harshestpressure calibration applications.
This technology provides unsurpassed control performance overa wide pressure range over an
extended life cycle, reducing
your downtime and maintenancecosts.

Modularity makes
maintenance a snap
The 8270A and 8370A make useof Fluke Calibration’s modular
platform design. Measurement
and control modules can beeasily removed through the front
panel to simplify maintenance or
re-ranging requirements.

Control speed meets thedemands of a manufacturing environment
With times to setpoint as low
as 30 seconds, the 8270A and8370A can control pressures
faster than traditional high-pressure controllers can.

Support for remote communication and automation
The 8270A and 8370A support
remote communication over
RS-232, GPIB, USB, and ethernet
connections. Using either thenative SCPI protocol or a varietyof emulation modes, these controllers can be used in a wide
range of automated processes.

Clean operation to 100 MPa(15,000 psi)
The wide pressure range control
allows you to use the sametest station for low, medium, or
high-pressure work. By usinga pneumatic pressure controller in your production process,you can provide your customers
with a clean product, free of oil
contamination.

Automate with COMPASS™
software
COMPASS for Pressure software enables you to automate
the 8370A and 8270A and run
complete pressure calibration
sequences on single or multiple

Notes
1. PM200 and PM230 gauge mode modules support absolute mode measurement when used with a barometric reference module. Instrumental
uncertainty for gauge mode modules used in absolute mode by addition of a barometric reference module is calculated as the uncertaintyof the gauge mode module root sum squared with the uncertainty of the barometric reference module. Uncertainty for gauge mode assumes
routine zeroing which is the default operating mode when used in a chassis. Uncertainty for absolute mode modules includes 1-year zerostability. This specification can be reduced to 0.05 % FS if the PM200 module is zeroed on a continuing basis to remove the 1-year zerostability component.
2. For modules with full scales <28 MPa (4,000 psi) temperatures from 15 °C to 18 °C and 28 °C to 35 °C, add 0.003 % FS/°C.
3. Can be used with 8270A only.
4. Can be used with 8370A only.

Notes
1. For PM600s modules with full scale less than 28 MPa, when used in absolute mode, root sum square (RSS) with 0.007 % of FS (reduced
to k=1 by square root of 3). This specification may be reduced or eliminated with the use of a separate more stable module as an AutoZero
reference.

2. PM600 and PM630 modules, with full scales of 28 MPa and higher, use an internal barometer in the PMM to correct for changes inbarometric pressure when they are used in gauge mode and as a zeroing reference when used in absolute mode, hence there is no need to
RSS 0.007 % FS.
3. Can be used with 8270A only.
4. Can be used with 8370A only.
5. ATM is any atmospheric pressure from 70 kPa to 110 kPa (10 psi to 16 psi absolute)
Operating characteristics
Control specifications
95 % of setpoints are within specification limits for stated conditions as calculated by mean plus 1.67 standard deviations of test data.
Control precision(Dynamic mode)

0.002 % Range Span or 0.01 kPa (whichever is greater)

Control turndown

100:1 (typical)

To meet the control specifications, supply pressure should not be greater than 100 times the range of the measurement module. Control
turndown is defined as the relationship between the provided supply pressure and the appropriate supply pressure for the range.
Low control point

1 kPa (0.15 psi) absolute (8270A only)
7 kPa (1.0 psi) gauge (8370A, 8270A without vacuum pump)

Settling time
Settling time is the time required to be within 0.005 % of setpoint for 10 % steps into volumes up to 50 cm3 for all pressures >7 kPa
absolute (8270A) or 7 kPa gauge (8370A). Settling time may be affected by multiple variables, including temperature effects, component flow
rates, leaks, and overall volume configurations.

8270A chassis supply port relief valve is set to 52 MPa (7,500 psi)
8370A chassis supply has a rupture disk installed which is designed to burst at 152 MPa (22,000 psi). Low pressure manifold relief valve is
set to 52 MPa (7,500 psi).
Modules with full scales ≤44 MPa include pressure relief valves.
