Description

Design

The CPC4000 offers a broad pressure range from -1 …
210 bar (-15 … 3,045 psi). This instrument can be
specified as a desktop or as a 19” rack-mounted device.
It can have up to two reference pressure sensors and
an optional barometer for displaying barometric
pressure or used to emulate gauge or absolute
pressure.

Application

Since the controller offers a measurement accuracy of
up to 0.02 %IS-50, and controls pressure with a high
stability, it is particularly suited as a production tool for
transmitter manufacturing, a calibration and
maintenance tool for pressure measuring devices or a
factory/working standard for the calibration of all types of
pressure measuring devices. The contamination
prevention accessories like the coalescing filter and
block and bleed valve make the CPC4000 an ideal
solution in oil and gas plants.

Functionality

The touchscreen, along with an intuitive user interface,
provide maximum ease-of-use. In addition, the large
number of menu languages add to its operability. The
device can have up to two internal pressure transducers
and the ranges for each unit are determined by the
customer within the allowable range.

Calibration Technology

Industrial Pressure Controller
Model CPC4000

Depending on the application, the operator can choose
between three methods of pressure control:

1) Direct numeric entry via keypad for the precise input of
the pressure value (set point) which will be controlled.

2) Define steps to reach the desired pressure value by
either defining fixed pressure increments or a
percentage of span value.

3) Program and store individual test sequences based on

users’ application.

Software

The WIKA-CAL calibration software enables the convenient
calibration of pressure measuring instruments and the
generation of test certificates. Additionally the device can
also be remotely controlled using the serial command
formats, the Mensor standard, SCPI or further optional
command sets are available.

Complete Test and Calibration Systems

On request, complete mobile or stationary test systems can
be manufactured. There is an IEEE-488.2, RS-232, USB
(along with an optional USB-WiFi adapter) and an Ethernet
interface for communication with other instruments, and
thus the instrument can be integrated into existing systems.

Optional barometric reference

Function The barometric reference can be used to switch pressure types 3), absolute <=> gauge. With gauge

pressure sensors, the measuring range of the sensors must begin with -1 bar (-15 psi) in order to carry
out an absolute pressure emulation.

Measuring range 552 ... 1,172 mbar abs. (8 ... 17 psi abs.)
Accuracy

1)

0.02 % of reading

Pressure units 38 and two freely programmable

1) It is defined by the total measurement uncertainty, which is expressed with the coverage factor (k=2) and includes the following factors: the intrinsic performance of the instrument, the
measurement uncertainty of the reference instrument, long-term stability, influence of ambient conditions, drift and temperature effects over the compensated range during a periodic zero
point adjustment.

2) 0.02 % IS-50 accuracy: 0.02 % of reading in the upper half of the measuring range.

3) For a pressure type emulation, we recommend a native absolute pressure sensor, since the zero point drift can be eliminated through a zero point adjustment.
