The Druck PV624 pressure controller is designed to be used with a DPI620G electrical calibrator and interchangeable PM620/PM620T pressure modules from the GENii advanced modular calibration system, creating a uniquely capable, flexible, self-contained portable hybrid pressure controller. The PV624 offers an easy and fast method to accurately maintain pressure set points. Hybrid pressure control also supports large test volumes and long battery life. With a robust design and tool-less pressure connection, the PV624 is ideally suited to perform pressure testing and calibrations in the field.

The PV624 automatically selects between fast high volume manual pressure generation and fully automatic precise pressure generation to quickly achieve and accurately maintain a stable setpoint. To achieve a fast time to up-scale pressure set points (or down-scale pressure set points for negative pressure ranges), the hand pump is requested by the PV624 to be exercised for a portion of the pressure change before automatically isolating the hand pump and seamlessly engaging fully automatic pressure generation to set point. Pressure set points are quickly achieved with automatically controlled venting. Once at set point, the PV624 automatically generates and controls the pressure to combat the effect of adiabatic or minor leaks.

The PV624 portable hybrid pressure controller connects physically or wirelessly via Bluetooth with any Bluetooth DPI620G electrical calibrator. A simple hand tight screw fit (no tools required) makes both an electrical and pressure connection to a range of fully interchangeable PM620/PM620T pressure modules. By using the PV624 internal barometer, a PM620 pressure module reference type can be changed by the user from gauge to pseudo absolute or from absolute to pseudo gauge.

The case material and precision over molding ensures that the PV624 is rugged, weatherproof, and suitable for the harshest environments. The PV624 is supplied with a dirt trap to reduce contamination of both the instrument and the system under test from dirt and debris as well as moisture.

The PV624 provides a tool-less quick-fit pressure connection where finger-tight connections achieve pressure-tight connections to 20 bar. It is supplied with a G1/8 female and 1/8 NPT female adapter. The PV624 is supplied with an AC adapter and a rechargeable battery pack that can be charged in the unit, or can be easily exchanged in the field with a charged additional battery.
