Automated Pressure Calibrators

In a portable package, this little calibrator can automatically generate from 90% vacuum to 375 psi (25bar) pressure with 0.005%FS pressure control stability and 0.02%FS accuracy. To improve the calibrator accuracy, two pressure modules with differing ranges are used. These are built-in and integrated with the internal pump and controller.

With optional external pressure modules (CDP series), the Additel 761 can measure pressures up to 10,000 psi (700 bar) with 0.025%FS accuracy. In addition to the pressure generation, control, and measurement capabilities, the Additel 761 also features HART communication capability, supply 24V loop power, and read the current or voltage produced by the pressure transducers. The state-of-the-art Additel 761 automated pressure calibrator brings automated pressure calibration to the field.
