3. Product Description

3.1 General Description

The Mensor CPC 6000 Automated Pressure Calibrator is a multi-channel/multi-range pressure system
designed to test and calibrate a variety of pressure devices in either absolute or gauge pressure
modes. The CPC 6000 can have two independent control channels each with its own pressure
regulator. Each control channel can have up to two transducers. Transducers can be of two types:

“Intelliscale Transducers” (IS) or “Turndown Transducers” (TD).
Intelliscale Transducers (IS) have an accuracy of 0.01%Intelliscale-50 (0.01%IS-50). This specification

is a percent of reading specification with a 365 day calibration stability and is explained in
this manual

. The 0.01%IS-50 specification is available in all new CPC 6000’s and applies to full scale
ranges above 15 psi absolute or gauge. CPC 6000s with software version 1.25 and below require a
software upgrade to version 1.26 or greater to be able to communicate with Intelliscale Transducers.

Turndown Transducers (TD) can have two ranges configured on each transducer. These ranges are
referred to as turndowns and each one has an uncertainty of 0.01%FS with a calibration stability of
185 days. The second (lower span) turndown cannot have a span that is less than 50% of the primary
turndown span. Turndown Transducers can be used in all CPC 6000 sofware versions.

Below is a software version comparison matrix.

3.2 Features

Here is a short list of significant features designed into the CPC 6000:

1. 0.01%Intelliscale-

50 Uncertainty.

2. Up to four (two per channel) highly stable, temperature compensated, pressure transducers.

3. An optional internal high accuracy barometric reference transducer provides gauge pressure emula
tion for all of the absolute ranges and absolute pressure emulation for gauge ranges;

4. All pressure transducers are individually removable from the front of the CPC 6000 without the use
of tools (excluding the barometric transducer). This feature greatly facilitates “out of instrument”
recalibration of individual transducers using the optional Calibration Sled (see

Section 8, Options);

5. Two precision pressure regulators are selectable for controlled output pressure. These regulators
have a history of excellent control and stability;

6. A separate electrical module using a high speed microprocessor. The operating program is loaded
from a non-volatile flash disk;

7. A large color SVGA LCD display with a touch screen for intuitive operator interface;

8. Multiple languages; change the language for on-screen text and number/date formats instantly by
simply touching one of the “national flag” cues available on the display The current language selec
tions available are listed under ‘

6.3.2 - Flag Symbol ‘in Section 6, Local Operation.

Operate the CPC 6000 while it is either sitting on a bench or mounted in a standard equipment rack.
Leveling the instrument is not a consideration since the pressure sensors are not affected by orienta

­tion. Use either front panel input (Local Operation), or send commands and queries over a bus from a
separate “host” controller (Remote Operation).

3.3 Front Panel

-

-

The CPC 6000 front panel (Figure 3.2) includes an 8.4 inch color SVGA display featuring touch screen
technology. Operator input is accomplished by pressing the words or symbols presented on the dis

-

play. There are no discrete keypads or switches on the front panel.
On the right hand side of the front panel, there is a clear window which shows the calibrated pressure

ranges of the internal transducers and the instrument serial number.
To gain access to the internal modules simply loosen the two thumb screws on the right hand edge of

the front panel and swing it open (Figure 3.3). In the front of the instrument directly below the electrical
module are slots to accommodate two pressure transducer modules on each control channel. Each
transducer can be removed and reinstalled through the front panel opening. See Section

9.3.1, Trans-

ducer Removal, for additional information on module removal and replacement.

3.6 Pneumatic Module

Pneumatic modules come in two types and are referred to in this manual as the “Pump Regulator”
or the “Solenoid Valve Regulator”. The pump regulator is used with low pressure sensors specified

Section 4, Specifications. The solenoid valve regulator is used with higher pressure sensors and

in
comes in three varieties:

■

High Pressure Solenoid Valve Regulator (HP SVR)

■

Medium Pressure Solenoid Valve Regulator (MP SVR)

■

Low Pressure Solenoid Valve Regulator (LP SVR)

Pressure limits for all of these are specified in Section 4, Specifications.

Each pneumatic module (Figure 3.6) includes platforms for up to two high performance pressure trans
ducers which are traceable to NIST standards. Both of these transducers can be used in conjunction
with the highly stable pressure regulator to produce a precise pressure output. Each transducer in

­cludes its own on-board compensation and calibration data so that any transducer can be replaced in
the instrument without requiring a recalibration.

3.7 Chassis Assembly

The chassis assembly acts as the housing for the system. The electrical and pneumatic modules are
each self-contained inside the chassis, and either can be replaced using basic hand tools. In addition,
each pressure transducer is individually removable without tools. Instructions for transducer and mod
ule removal are provided in

The only moving parts in the CPC 6000 are the fan, the pneumatic flow controller diaphragms and
valves, the pump/motor, and the solenoid valve plungers. There are no internal user adjustments or
setup switches.

■

Power cord

■

1/8 inch FNPT fitting adapters fastened to rear panel

■

Any accessories ordered

■

An envelope containing the Calibration Certificate

Your new instrument was subjected to many hours of functional testing before it left the factory. In
addition to testing, the unit was inspected for appearance prior to being packaged for shipment. Upon
removal from its carton please examine the instrument for shipping damage. Report any apparent
damage to the carrier immediately.

5.3 Mounting

The instrument can be set up on a table top or it can be rack-mounted. Rack mount adapters are
optional on the CPC 6000 and require an adapter panel (see “
Options). The special sensors used in the CPC 6000 are relatively insensitive to tilt and vibration.
However to further assure stability and accuracy, avoid mounting the instrument on surfaces subject
to excessive motor or machinery vibration.

Notice

Notice

All of the pressure ports on the rear are female 7/16 - 20 SAE/MS straight threads per MS16142 and
SAE J514 table 14. They require a tube fitting boss seal with an o-ring per MS33656. Mensor provides
female 1/8” NPT adapter fittings with the instrument. The pressure connections can be made to these
adapters with the proper mating hardware. We recommend the use of either Loctite® Hydraulic Seal
ant or new teflon tape on the threads of any male pipe fitting. Do not use sealant on fittings sealed
with an o-ring. The integrity of each seal is particularly important since even microscopic leaks can
cause errors in pressure measurements. The rear panel connections and a complete pneumatic sche
matic, including the optional secondary transducer, are provided in the
Figures 9.2.1C and 9.2.2B). Requirements for connecting to the ports on the CPC 6000 manifold are
as follows:

5.5.2 Measure/Control Port

Connect a device to be tested to the MEASURE/CONTROL port. In MEASURE mode the CPC 6000

recommended pressure can cause permanent damage to the control channel.

Performance can be enhanced with a well-regulated source pressure.

WARNING: HIGH NOISE LEVELS! As pressure decreases compressed gas will
escape out the exhaust port. For ranges above 600 psi high noise levels may result
during such pressure releases. To overcome objectionable exhaust noise either
install a muffler or route the port to a remote location.

5.5.3 Exhaust Port

If sub-atmospheric control pressure is required a vacuum pump must be connected to the EXHAUST
port. Otherwise, this port may be left open to atmosphere.

5.5.4 Reference Port

On gauge units this port is connected to the reference side of the transducer, and on absolute units it
is internally capped. This port is normally left open to atmosphere but may be attached to a snubber
assembly on very low pressure instruments.
