Pressure Controller/Calibrators
Hydraulic Pressure Controller/Calibrator Gas Pressure Controller/Calibrator Hydraulic Gauge Calibrator Pneumatic Gauge Calibrator Hydraulic Electronic Deadweight Tester

Automated Pressure Controller/Calibrator

DHI's fifth generation pressure controller/calibrator, continues to break new ground with an unprecedented combination of high end performance, operational versatility and long term reliability.

Choose your local user interface to best fit your application and budget.
    • For bench top users, the new graphic color display with point-and-click navigation will
      streamline your pressure calibration and testing task.
    • For system applications and where PPC4 will spend most of its time interfaced with a
      computer, choose the basic front panel.

Q-RPT (quartz reference pressure transducers:

Three different Q-RPT quartz reference pressure transducer) measurement classes available to fit different performance requirements.

Full Scale Standard (f), Standard (s), and Premium (p) Classes.

The AutoRange™ feature supports infinite ranging, automatically optimizing all aspects of
operation for the exact range to be explored and bringing a new dimension in rangeability to
pressure controllers.

Patented positive shut-off pressure control gives 50:1 control turndown.

Open architecture allows nearly limitless system configurations to adapt to your specific
application's requirements.

PPC4 carries on the PPC line's tradition of combining very high end performance with
ruggedness and reliability.

Automated self purging liquid trap (SPLT) accessory is available for protection against
liquid contamination.

PPC4 includes flash memory for simple and free embedded software upgrades

The Command Interpreter feature allows PPC4 to interpret and respond to custom remote
commands including commands used by non-PPC4 pressure controllers and can be
downloaded free at: CI Editor™

Hydraulic Deadweight Tester Performance with Digital Measurement Convenience

E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder and weight based deadweight testers. It’s a lighter weight, easier-to-use deadweight tester alternative that is at home in the lab or instrument shop, as well as in the field performing in-situ calibrations and tests.

E-DWT-H offers precision, low measurement uncertainty and the stability over time of a conventional deadweight tester without the inconveniences associated with the piston-cylinders, weights, hand pumps, and interconnecting plumbing.

    • No weights to load and unload or regularly send out for calibration
    • No need to know and correct for local gravity or ambient temperature
    • No piston-cylinder changes; switch Q-RPT ranges in seconds
    • Not sensitive to level or vibration
    • Able to set and read any pressure value exactly, no minimum increment limited by
      smallest available masses
    • Operates in any unit of measure while deadweight tester is typically limited to the
      pressure unitstamped on the mass
    • Perfect for applications that require setting a nominal pressure precisely on the
      device under test and measuring it, such as analog gauge calibration
    • On-board, AutoTest calibration routines and data acquisition
    • Interfaceable with a PC or laptop to allow for automated data acquisition
    • Two year calibration interval supported at measurement uncertainty of ± 0.025% of reading.
    • Easily recalibrated without crossfloating. Automated calibration of E-DWT-H is
      possible using COMPASS® for Pressure software.

Q-RPT (quartz reference pressure transducer)
module advantages:

In addition to outstanding metrological characteristics,
Q-RPT modules offer the advantages of:
    • Negligible warm-up time
    • Quartz element isolated from test medium
    • Minimal sensitivity to orientation

AutoTest™ lets E-DWT operators quickly define test points and adjust all of the range-dependent settings with a single function.

The resolution and stability test used by the RPM4-E-DWT are set according to the range of the device under test. The upper limit setting is also set and provides range-based warnings and overpressure protection. While running AutoTests, the operator is prompted to set each sequential test point and test data is stored in the RPM4-E-DWT for recall or download. Typical test setup is quick and easy, but more complex tests can also be stored and reused.

E-DWT-H can be configure to provide uncertainty of ± 0.02% of reading from 1% to 100% of
full scale range.

Low torque variable volume allows for pressure generation up to 200 MPa (30,000 psi) with V minimal physical effort.

AutoRange feature optimizes measurement, control and safety features for the specific range
of the instrument being calibrated

E-DWT-H includes everything to set, adjust and read pressure in one compact, transportable
package and the rechargeable battery pack option provides for eight hours of field operation.

E-DWT-H includes flash memory for simple and free embedded software upgrades.
