Modular Pressure Controller
CPC6050

3 General Description

The CPC6050 Modular Pressure Controller is a multi-channel / multi-range automatic pressure controller
designed to test and calibrate a variety of pressure devices such as pressure gauges, pressure switches,

sensors, transducers and transmitters in either absolute gauge, bidirectional or dierential pressure

modes. The CPC6050 can have up to two independent control channels (two pressure control outputs
working independently) and an optional barometric reference for gauge or absolute emulation. When two

channels are installed, a Delta Channel mode can be enabled that will display the dierence between

Channel A and B (either A-B or B-A). Each control channel has its own pressure regulating module
(either a Low Pressure Pump Module or a Solenoid Valve Regulator Module) and up to two transducers
per module. The CPC6050 is available as a desktop or a rack mountable instrument.

Optional congurations of the CPC6050:

1. Single Output / Auto Range Version: Provides a single out-

put over the total range of the two internal control modules
and across the range of four internal transducers; 400:1
turndown.

2. Single Output / Dual Channel Version: Provides a single

output with a choice of controlling with the internal control
module A or B.

3.5 Chassis Assembly

The chassis assembly is the housing for the system. The control modules and transducers are each self­contained inside the chassis and either can be replaced using basic hand tools.

Figure 3.5 - Chassis Assembly

3.5.1 Control Module

The control module is referred to as the “Solenoid Valve Regulator” (SVR Module) or the "Pump Module."
The Pump Module is available in a single version and the SVR Module is available in four variations de­pending on the working pressure range:

• Low Pressure Pump Module (LPPump)

• Low Pressure SVR Module (LPSVR)

• Medium Pressure SVR Module (MPSVR)

• High Pressure SVR Module (HPSVR)

• Extra High Pressure SVR Module (EPSVR)

Pressure limits for all of these are specied in Section 4, Specications.

Each control module includes platforms for up to two high performance pressure transducers, CPR6050,
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 output. Each transducer includes its own on-board
compensation and calibration data so that any transducer can be replaced in the instrument without
requiring a recalibration.

5.3 Mounting

The instrument can be set up on a desk top or it can be rack-mounted. Rack mount hardware is optional
on the CPC6050 (see Section 5.2 Dimensions and Section 8, Options).

The special transducers used in the CPC6050 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.

5.4 Rear Panel

Up to eleven pneumatic pressure ports are located across the rear panel. The channel with gauge trans­ducers will have a reference and a pressure port. The channel with absolute transducers will use the
pressure port. In the upper right corner next to the instrument label is a 10-32 UNF tting, which is con­nected to the barometric reference if installed. The connections for digital I/O for each channel are lo­cated on the top on either side of the ventilation fan. Positioned on the right side is the RS-232, Ethernet,
IEEE- 488, USB device connections for communication, the USB host connection and the 12 VDC power
input.

5.4.1 Pressure Connections

Warning! The pressure connections must be installed according to the following

instructions, observing the relevant regulations. The installation is to be per-

!

Warning

i

Notice

All pressure ports on the rear apart from the Vent Port are female 7/16 - 20 SAE/MS straight threads per

MS16142 and SAE J514 table 14. Connected adaptors require a tube tting boss seal with an o-ring per
MS33656. Mensor can provide a variety of adapter ttings (see Section 8 Options) with the instrument.
Do not use sealant on ttings sealed with an o-ring. The integrity of each seal is particularly important

since even microscopic leaks can cause errors in pressure measurements.

Operating Instructions - CPC6050 23

formed by trained, authorized personnel, knowledgeable in the safety regulations
for working on pneumatic/hydraulic systems

Up to 11 pressure connections are on the rear panel. Pressure connections that are not

assigned are plugged.

Modular Pressure Controller
CPC6050

5.4.2 Supply Port

The pressure supplied to the pressure connection labeled “Supply” should be approximately 10% higher
than the full scale of the highest pressure transducer installed in the controller channel or 10 psi, which-

ever is greater. With a Pump Module, supply pressure is turned o for primary transducers with pressure

ranges less than 3 psi. Supply pressure to a Pump Module is only necessary if it is called for to increase
the control speed. In this mode, a Pump Module will use the supply pressure to quickly control close to
the set point before the internal pump takes over and ramps into the set point with precision.

5.4.3 Exhaust Port

The pressure connection labeled “Exhaust” is for the vacuum supply. In a gauge pressure version it can
be left open to atmospheric pressure.

5.4.4 Vent Port

The pressure connection labeled “Vent” is the port where the system pressure is vented to the atmo­sphere under certain conditions. Leave this port as is.

5.4.5 Measure / Control Port

The Measure / Control port (when in the Control mode) supplies pressure that is precisely controlled by
the controller. In the Measure mode, a pressure applied to the Measure / Control port is measured by the
internal transducers.

5.4.6 Reference Port

The reference port is available on gauge units that have transducers that are not sealed gauge units. For
these units this port is available to connect to the reference side of the transducer. This port is normally
left open to atmosphere but may be connected to a stable reference pressure. In an absolute pressure
transducer this port is not used.

5.4.7 Barometric Reference Port

The Barometric Reference port is connected to the optional internal barometer and should be left open to
atmospheric pressure.

5.5 Remote Communication Connections

See Section 7, Remote Operation, for connections and commands for operation over IEEE-488, Ether­net, USB or RS-232 ports.

5.6 Power Up

Apply power to the power connector on the rear of the instrument using the power adaptor included, and
switch the power switch on the front of the unit ON. The instrument will go through an initialization pro­cess and system check. As soon as the system check is completed the system will default to a screen
similar to the one shown in Section 6.1.2 - Display Screen Features. The main measurement screen may

be congured in many dierent ways but initially it will be in a default conguration. Subsequently, the unit
will power up in the conguration that it was in when last powered o. Allow at least 15 minutes of warm

up before performing critical pressure measurements.
