Enhanced PPC4 pressure controller/calibrator from DHI adds lower pressure control range and new features, now up to 2,000 psi

Sydney, December 1, 2009 –The DH Instruments (DHI) division of Fluke Corporation has announced a significant enhancement to its PPC4 precision pressure controller/calibrator product line.

PPC4 is a high performance pressure calibrator for testing pneumatic pressure instruments. It is designed to provide versatility and ease of use in calibration labs and manufacturing environments.

The maximum pressure range of the PPC4 has increased to cover the absolute pressure range of 1 kPa (0.15 psi) to 14 MPa (2,000 psi) and gauge pressure equivalent, including very low differential pressures.

The patented dynamic control is further improved, extending the minimum controlled pressure down to 1 kPa.

PPC4 offers industry-leading control precision to ensure the lowest total uncertainty on dynamically controlled pressures and to maximise the range covered by a single controller.

PPC4 lets users select the user interface that best fits their application and budget. Bench top users can select the advanced graphic colour display with point-and-click navigation to streamline pressure calibration and testing tasks.

The advanced graphical user interface now supports 11 different languages including Chinese, Czech, English, French, German, Italian, Japanese, Portuguese, Russian and Spanish.

PPC4 includes a front panel universal serial bus (USB) connection and free cockpit software for full PC-based ‘plug and play’ functionality.

DHI’s COMPASS for pressure calibration assistance software provides an advanced off-the-shelf tool to automate calibration and testing processes quickly and handle a wide array of special requirements.

PPC4 uses DHI’s 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.
