GE Druck Pressure Calibrator

DPI 330/335

Portable hydraulic high pressure calibrators generate pressures up to 10,000 psi

The GE Druck DPI 330 / 335 pressure calibrator is designed to make the calibration of hydraulic systems and instrumentation quick and simple. Two versions are available - the GE Druck DPI 330 pressure calibrator is the standard model with RS232 interface, and the GE Druck DPI 335 pressure calibrator has full documenting capability.

The GE Druck DPI 330 / 335 pressure calibrator provides unparalleled accuracy and performance. Hydraulic pressures up to 10,000 psi (700 bar) can be generated quickly and easily with excellent setpoint control.

Unique Priming System

The GE Druck DPI 330 / 335 pressure calibrator uses a unique priming system to conveniently fill the hydraulic system under test. The pressure / vacuum selector valve, combined with the priming pump, first evacuates the system and then fills the system with fluid from the reservoir and generates the initial pressure. Once the system is primed, any desired pressure can be easily set using the GE Druck DPI 330 / 335 pressure calibrator's pressure pump and volume adjuster.

Excellent Control Stability

The GE Druck DPI 330 / 335 pressure calibrator's thermal compensators eliminate adiabatic thermal effects which are generated by pressure changes within the hydraulic system. This innovative feature holds the generated pressure steady while a nudge facility allows the exact pressure to be set. Overall test / calibration time and precision is significantly improved with the GE Druck DPI 330 / 335 pressure calibrator.

Dual Channel Display

The GE Druck DPI 330 / 335 pressure calibrators are dual channel instruments able to display the input and output values simultaneously. Capable of providing current and voltage excitation to the device under test, the GE Druck DPI 330 / 335 pressure calibrator can measure DC voltage, DC current, and ambient temperature. Electrical terminations are made via industry standard 4 mm sockets, and the large backlit display provides a clear readout of the process parameters.

Application Specific Task Menu

A dedicated task key provides instant access to the GE Druck DPI 330 / 335 pressure calibrator's task menu permitting the pressure calibrator to be configured for specific applications. For example, the P-I task configures the GE Druck DPI 330 / 335 pressure calibrator to source pressure and measure current. 24 VDC loop power is also available to allow complete pressure transmitter calibration. Running the Pressure Switch task captures the open and closed switch values and calculates switch hysteresis. The contact resistance of the switch can also be monitored.

Reduced Process Downtime

The GE Druck DPI 335 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 i4i (Intecal for Industry) calibration management software, test procedures can be downloaded to the from a PC to the GE Druck DPI 335 pressure calibrator. The pressure calibrator will prompt the technician during the calibration routine and the results will be recorded electronically, reducing plant downtime and human errors.
