Unique Priming System
The DPI 330/335 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 pressure pump and volume adjuster.
Excellent Control Stability
The thermal compensator eliminates 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.
Dual Channel Display
The DPI 330/335 are dual channel instruments able to display the input and output values simultaneously. The calibrators are capable of providing current and voltage excitation to the device under test and 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 task menu permitting the calibrator to be configured for specific applications. For example, the P-I task configures

the 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 DPI 335 version 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 DPI 335 from a PC. The calibrator will prompt the technician during the calibration routine and the results will be recorded electronically, reducing plant downtime and human errors.
