DHI PPC4 pressure calibrator

DHI has announced the PPC4 pressure controller and calibrator, a high-performance instrument designed to provide versatility and ease of use in calibration labs and manufacturing environments.

The DHI PPC4 covers the absolute range of 1 kPa (0.15 psi) to 10 MPa (1500 psi) and gauge equivalent including low differential pressures.

With an emphasis on high-end performance, the DHI PPC4 minimises measurement uncertainty while maximising the ranges covered by a single controller. The device includes exclusive, individually characterised, quartz reference pressure transducer (Q-RPT) modules for increased precision and reduced measurement uncertainty.

The AutoRange feature supports infinite ranging, automatically optimising all aspects of operation for the exact range of the device being calibrated. It is rugged enough for mobile applications and standard shipment without special packaging.

The DHI PPC4 lets users select the interface that best fits their application and budget. The basic front-panel option is best if operation is usually under computer control. The advanced user interface with colour graphic display and point and click navigation is designed to streamline operator-controlled pressure calibration and testing tasks.

Both interfaces include a front-panel USB connection and free cockpit software for full PC-based plug-and-play functionality. Other features of the DHI PPC4 include: pressure 'ready/not ready' indicator with user-adjustable criteria; real-time calculation and display of the uncertainty in the set pressure; high dynamic control precision and control turndown; open architecture that gives nearly limitless system configurations to adapt to specific applications requirements; and flash memory for simple and free embedded software upgrades.
