Description of the digital pressure indicator

Application
The model CPG2500 digital pressure indicator is used in calibration laboratories and manufacturing facilities as a source for precise pressure measurement. It is used to verify the accuracy of field pressure indicators/transmitters or as a laboratory standard and wherever there is a need for a high level of pressure accuracy in manufacturing, testing and calibration of pressure instruments or gauges.

Functionality
The digital pressure indicator CPG2500 can be configured with one, two or three pressure sensors. Two sensors are internal, and the third is external. The pressure sensors of the digital pressure indicator are pneumatically isolated so that one channel can be configured with a sensor as high as 2,890 bar (42,000 psi) and another as low as 25 mbar / 10 inH₂O at the same time. An optional barometric sensor can be added internally to display barometric pressure or used to emulate gauge or absolute pressure. Pressure ranges for each channel are specified by the customer.

The built-in pressure sensors of the digital pressure indicator are available as standard and premium sensors. As an external reference pressure sensor, Mensor’s CPT9000, CPT6100 or CPT6180 precision pressure sensors are used.

The advantage of IntelliScale and removable sensors
With the IntelliScale specification, each sensor is calibrated so that the accuracy in the lower part of the measuring range is referenced to a fixed error, and in the upper part of the measuring range the accuracy is referenced to the measured value. Three sensors can be configured so that the percent of reading portions of their ranges are contiguous, giving a percent of reading uncertainty over a wide range.
In addition, each reference pressure sensor is removable and interchangeable which allows an external recalibration and range changes while minimising downtime.
