Druck DPI 603 Portable Pressure Calibrator

    The DPI 603, which extends the Druck range of rugged portable battery powered pressure calibrators, with standard ranges of -14.7 to +15 psi, 30 psi, 100 psi or 300 psi gauge and an accuracy of +/-0.075% F.S.

Designed for use in remote locations where AC power is not available, the DPI 603 enables pressure instrumentation to be serviced and calibrated.  The instrument features the capability to generate pneumatic test pressures with an integral hand-pump up to 300 psi.  A volume adjuster provides fine control of the desired test value and a venting valve enables pressure release without disconnection of the device under test.  An optional pressure/vacuum switching facility can also be provided, which enables the hand-pump to source vacuum down to -22' Hg or pressure up to 300 psig.

To facilitate pressure transmitter testing and calibration a 24VDC power supply is provided and the ability to monitor the current loop from 0 to +/-55 mADC.  For loop verification, the DPI 603 can also output a single 12mA test value, or provide a passive sink if required.  The clear LCD allows readout of pressure, voltage and current parameters with the ability to show current or voltage simultaneously with pressure.
