GE Druck Pressure Calibrator

DPI 320/325

Portable pneumatic high pressure calibrator generates pressures to 3000 psi

The portable pneumatic GE Druck DPI 320 / 325 pressure calibrator for high pressures is the latest addition to a comprehensive range of compact and rugged instruments. GE Druck DPI 320 / 325 pressure calibrators are designed to make testing and calibration of high pressure instruments and systems both quick and simple.

Two versions are available: the GE Druck DPI 320 pressure calibrator, which is the standard model, and the GE Druck DPI 325 pressure calibrator, which has full documenting capability.

The self-contained and portable GE Druck DPI 320 / 325 pressure calibrator provides unparalleled accuracy and control performance. A built-in gas cylinder provides source pressures up to 3000 psi (200 bar), and a precision pressure regulator and fine volume adjuster ensures optimum control. The GE Druck DPI 320 / 325 pressure calibrators have a digitally characterized sensor measures pressure to better than 0.025% of FS.

Field and Workshop Operation

The GE Druck DPI 320 / 325 pressure calibrator is designed for use in the workshop, in the plant, or out in the field. The large capacity gas cylinder ensures maximum productivity between refills.

GE Druck DPI 320 / 325 pressure calibrators can be operated directly from an external pressure source connected to the charging port.

Dual Channel Display

The GE Druck DPI 320 / 325 pressure calibrators are dual channel instruments, able to display both the input and output values simultaneously. Capable of providing current and voltage excitation to the unit under test (UUT), the GE Druck DPI 320 / 325 pressure calibrator can measure DC voltage, DC current, and ambient temperature.

Electrical terminations are made by industry standard 4 mm sockets, and the large backlit display provides a clear readout of the process parameters.

Application Specific Task Menu

The GE Druck DPI 320 / 325 pressure calibrator features a dedicated task key that provides instant access to the task menu, permitting the pressure calibrator to be configured for specific applications. For example, the P-I task configures the calibrator to source pressure and measure current at 24 VDC. Loop-power is also available to allow complete pressure transmitter calibration. Running the pressure switch task captures the open and closed switch value and calculates switch hysteresis. The contact resistance of the switch under test can also be monitored.

Reduce Process Downtime

The GE Druck DPI 325 pressure calibrator enables calibration criteria to be easily entered via the keypad, allowing fast diagnosis of field instruments and automatic reporting of errors with a Pass or Fail status. When used in conjunction with Intecal for Industry (i4i) calibration management software, it will be possible to download test procedures from a PC to the GE Druck DPI 325 pressure calibrator.

The GE Druck DPI 325 pressure calibrator will prompt the technician during the calibration routine, and the results will be recorded electronically, reducing downtime and eliminating human errors.
