System Overview
The SPC4050 pressure calibrator is designed toprovide automated calibration of Scanivalve DSA,ZOC, and MPS series pressure scanners. Thecalibration system consists of 3 components:
1. The heart of the calibration system isthe Scanivalve pressure calibrator, model
SPC4050. The SPC4050 calibrator has up totwo independent precision pressure regulators.
Each regulator can have up to two gauge orabsolute transducers; thus up to 4 transducers per
calibrator. Transducers can be quickly removed forcalibration or service.
The transducers are Gauge (psig) or Absolute(psia). Full Scale Gauge pressure ranges areavailable between 0.36 psig and 750 psig.
2. Scanivalve’s Pneumatic Logic Unit (SPCPLU)
is required for automated DSA, ZOC, and MPS
calibrations. This unit contains the pneumaticsolenoid valves and manifolds required to perform
single or multi-range calibrations, as well as zero
offset corrections.
3. A utility program, PressCal is included with
the SPC4050. It performs automated or manual
calibrations on all DSA and ZOC pressure
scanners by controlling the pressure calibrator
and SPCPLU. The PressCal program is hosted ina Windows® environment. PressCal updates themodule calibration coefficient files and generates“as received” and calibration validation reports.

SPC4050 SystemApplications

This SPC4050 pressure calibrator is based on theMensor Corp. model CPC6050 pressure calibrator
with specific changes made to work with Scanivalve
products. These changes include additional digital
outputs to control the SPCPLU as well as modified
OEM firmware to accept Scanivalve commands.
In order to perform multipoint calibrations andzero offset corrections on demand to DSA, ZOC,
and MPS pressure scanners, the calibrator must
be used with the SPCPLU. The reference side ofthe gauge transducers can be connected to analternate remote location (tunnel static, elevatedline pressure, static basket, etc).
The calibration system can be used for many
applications including multi-point calibration of DSA
ZOC, and MPS pressure scanners, zero offset
correction, and leak testing.
The calibrator can also be used in the local/
manual mode utilizing the front panel touch
screen or remotely via Ethernet. It would beused in this standalone mode to regulate andmeasure pressures to calibrate individual pressuretransducers. It could be used to send knownpressures to all of the DSA, ZOC, and MPS
sensors to ensure they are reading correctly(System Validation).

Modular Calibrator Design
The SPC4050 brings a high degree of flexibility
by having a variety of configurations available.
It can have one or two independent pressure
regulators providing two pressure outputs.
Each regulator can have up to two transducers.Each transducer module contains all of thecalibration,characterization, communication
functions and information needed to communicate the pressure reading to the system electrical module.
Transducer modules can be easily removed orreplaced. Compatible spare transducers of thesame or different range can be interchanged toincrease utilization.

The other 3 regulators are determined by therange of calibrator transducers selected. The
appropriate regulators will be matched for thespecific transducer pressure ranges. These
regulators require an external pressure source thatis approximately 10% above the full scale range ofthe highest internal pressure range.

All regulators can be tuned in the field to meet a
specific customer external volume requirement.
Specific control requirements, such as control speed,overshoot, and external volume, are just a few of thevariables the regulator is able to accommodate.

The Regulator

The SPC4050 has four unique pressure regulators
available depending on transducer ranges selected.
The Pump Regulator utilizes a pump to both generate
and regulate pressure. It can generate pressures aslow as 0.5 psia and is generally used when extreme
precision is needed at very low gauge pressures orwhen an external pressure source is not available.

The transducers are configured in a proprietaryprocess characterizing each pressure range overtemperatures from 15 to 45° C. This process has
been optimized to provide the greatest accuracy,stability, and reliability. Each range is calibrated with
NIST traceable primary standards and provided witha calibration certificate.
Transducers 15 psi and above have an uncertaintyof +/- .01% F.S. with a one year calibration interval.
Transducers 14.9 psi to 1 psi have an uncertainty
of +/- .01% F.S. with a one year calibration interval.
Transducers less than 1 psi have an uncertainty
of +/- .03% F.S. with a one year calibration interval.

Standalone/Manual Calibration
Manual calibrations can be performed with theSPC4050 by using either the color touch screenor remote commands via Ethernet. This manualmode using remote commands can be usedwith Scanivalve’s DSA, ZOC and MPS pressurescanners. When calibrating individual pressuretransducers, the touch screen or remote commands
may be used.

General Description

The calibrator system consists of 3 components:
1. SPC4050 calibrator
2. The Pneumatic Logic Unit (SPCPLU) is a box that
contains pneumatic solenoid valves and manifolds
required to perform single or multi-range DSA & ZOC
calibrations, as well as zero offset corrections. It also
switches the DSA or ZOC calibration valve into sense,
calibrate, purge, and leak test modes.
3.Scanivalve’s PressCal software program
orchestrates the pressure calibrator and SPCPLU toperform automated and manual calibrations.
