Wika Mensor’s CPC4000 Industrial Pressure Controller delivers an expansive pressure range from -1 … 210 bar (-15 … 3,045 psi). It’s available as a desktop or as a 19" rack-mounting kit. The CPC4000 is equipped for up to two reference pressure sensors and an optional barometer for showing barometric pressure or can be used to imitate gauge or absolute pressure.
With an accuracy of up to 0.02 % IS-50, and able to control pressure with a high stability, it is particularly apt as a production tool for transmitter manufacturing, a calibration and maintenance tool for pressure measuring instruments or as a factory/working standard for the calibration of all types of pressure measuring instruments.
The CPC4000’s touchscreen and effortless menu navigation provide for a user friendly operation. More still, for the utmost user flexibility, depending on the application, the operator can choose between three set-point methods:
- Direct entry of the pressure value (set point) which will be controlled via touchscreen keypad.
- Define steps to reach the desired pressure value by either defining fixed pressure increments or a percentage of span value.
- User-defined programmable test sequences.

Optional barometric reference | ||
Function | The barometric reference can be used to switch pressure types 6), absolute <=> gauge. With gauge pressure transducers, the measuring range of the transducers must begin with -1 bar (-15 psi) in order to carry out a complete absolute pressure emulation. | |
Measuring range | 552 ... 1,172 mbar abs. (8 ... 17 psi abs.) | |
Accuracy 1) | 0.02 % of reading | |
Pressure units | 39 and two freely programmable | |
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) FS = full span 3) 0.02 % IS-50 accuracy: Between 0 ... 50 % of the full scale, the accuracy is 0.02% of half of the full scale value and between 50 ... 100 % of the full scale, the accuracy is 0.02 % of reading. 4) The minimum calibrated range of absolute transducer(s) is 600mTorr 5) It is defined as the combined effects of linearity, repeatability and hysteresis throughout the stated compensated temperature range 6) 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. |
