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.
Figure 3.1 - Desktop version
Note: Some screens in the following sections may appear slightly dierent from units with options.
See conguration options described in more detail in Section 8 - Options.
3.1 Features
Here is a short list of signicant features designed into the CPC6050:
• Up to four (two per channel) removable / interchangeable, highly stable, temperature compensated,
internal pressure transducers.
• Extended operating pressure range from -15 … 3,045 psig/ -1 … 210 bar or 0 … 3,060 psia/ 0 … 211
bar absolute.
• 0.01% Intelliscale-50 accuracy.
• Easily removable transducers from the front of the CPC6050 without any external tools.This facilitates
“out of instrument” recalibration of individual transducers using the optional calibration sled.
• An optional removable / interchangeable internal high accuracy barometric reference transducer
providing gauge pressure emulation for absolute ranges and absolute pressure emulation for gauge
ranges.
• Delta Channel mode (A-B or B-A).
• 8.9” color LCD display with touch screen.
• Switch test, Leak test and Burst test application.
• Multiple languages; change the language for on-screen text and number/date formats by simply
touching one of the “national ag” icons available in the setup screen.
• Desk top or rack mount
• Local operation, or command and read remotely.
• Low Pressure Pump Module. Provides an internal low pressure source.

3.3 Front Panel
The CPC6050 front panel includes an 8.9” color LCD display with touch screen. Operator input is ac-
complished by pressing the words or symbols and the App icons presented on the display.There is a
single discrete on/o button and a USB on the right hand side. The front panel is hinged for easy access
to remove or replace the transducers inside. The instructions for accessing the transducers are provided
in Section 9.3 Transducer Removal. The front panel also shows the model number designation and brand
logos.

3.3.1 Power Switch
The power switch is a two-state device with an action similar to that of a ball point pen. Push the button
with enough force to latch it in to turn the unit ON. Push it again to release it to turn the system OFF.
i
Notice
If power to the instrument is interrupted while ON it will shut down until the power is
restored, then immediately resume operation.
3.3.2 USB Port
The front panel USB port acts like the Host USB and is intended for future expansion or software up-
grades.

3.4 Display
The display is made up of two sections. In the main screen (“Home Application”), the left three fourths
shows the operating screen with the two independent channels; Channel A and Channel B. Each chan-
nel displays the active pressure reading, units, mode (absolute or gauge), active range of the internal
transducer, pressure control setpoint, a bar graph (if enabled), an auto zero or tare button (if enabled)
and any auxiliary displays that have been chosen. The right one fourth of the screen has Application
Icons (“Apps”) for setting general instrument settings, control settings, display settings, program settings,
favorites plus a “Next Page” button [ ] that, when pressed, shows a second and third page of icons
for remote communication, troubleshooting, switch test, leak test, digital I/O and service applications.

Buttons, Labels and Windows: The CPC6050 touch screen has many buttons with relevant graphic
icons or text which, when touched, will open a related window where changes can be made or informa-
tion viewed. Some of these buttons will toggle from one state to another, others present choices or dis-
play a numerical data entry screen. Text or icons that are displayed, but do not respond to being touched,
are called labels or windows. Operators will quickly become accustomed to the particular characteristics
of the frequently used buttons.
Main Screen: The main screen or “Home Application”, appears after power-up. This screen contains the
operating screen and Settings application screen. It will remain as congured after a power cycle.
Operating screen: The operating screen (left 3/4 of the main screen) contains information relevant
to the measurement. Up to three auxiliary displays can be shown simultaneously along with the cur-
rent pressure value.This screen is divided in two parts and color coded as green for Channel A and as
blue for Channel B by default. The display can be congured to either as one or two channel displays by
expanding either of the two channels to occupy complete operating screen using the “Channel Expand”
buttons [ ] or [ ]

3.5 Chassis Assembly
The chassis assembly is the housing for the system. The control modules and transducers are each self-
contained 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 de-
pending 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.

1) It is dened by the total measurement uncertainty, with the coverage factor (k = 2) and includes the intrinsic performance of the instrument, the measurement uncertainty of the reference
instrument, long-term stability, inuence of ambient conditions, drift and temperature eects over the compensated range with recommended zero point adjustment every 30 days.
2) FS = full span
3) 0.01 % IS-50 accuracy: Between 0 ... 50 % of the full scale, the accuracy is 0.01% of half of the full scale value and between 50 ... 100 % of the full scale, the accuracy is 0.01 % of reading.
4) The minimum calibrated range of absolute transducer(s) is 600mTorr
5) It is dened as the combined eects of linearity, repeatability and hysteresis throughout the stated compensated temperature range
6) 180 days for pressure ranges below 1 bar (15 psi) gauge or absolute, and -1 ...1 bar (-15 ... 14.5 psi) bidirectional. 365 days for the remainder of the specied ranges.
7) For a pressure type emulation, we recommend a native absolute pressure transducer, since the zero point drift can be eliminated through a zero point adjustment.
