Wika Mensor’s CPG2500 digital pressure indicator is crafted for verifying the accuracy of field pressure indicators/transmitters or as a laboratory standard and wherever there is a requirement for a high level of pressure accuracy in manufacturing, testing and calibration of pressure instruments or gauges.
The CPG2500 is able to be configured with up to three pressure sensors. Two sensors are internal, and the third is external. The pressure sensors of the digital pressure indicator are pneumatically isolated, allowing one channel to be configured with a sensor as high as 690 bar (10,000 psi) and another as low as 25 mbar / 10 inH2O simultaneously. Users can add an optional barometric sensor internally to present barometric pressure or used to imitate gauge or absolute pressure. Pressure ranges are user specified.
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 CPR2510, CPT6100 or CPT6180 precision pressure sensors are used.
Even more, the IntelliScale specification ensures 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 vast range.
Each reference pressure sensor is detachable and interchangeable permitting external recalibration and range alterations while curtailing downtime.

(1) It is defined 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, influence of ambient conditions, drift and temperature effects over the compensated range with recommended zero point adjustment every 30 days.
(2) 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.
