The Druck IO624‑LPA is an advanced low-pressure accessory that transforms the PV624 and DPI620G into a fully automated low‑pressure calibration system. It delivers precise, repeatable pressure generation and control up to ±500mbar (50kPa/7.25psi) with a 12-month uncertainty of 0.05%. Ideal for the calibration of differential pressure gauges and process transmitters on a manifold, Druck IO624-LPA excels in large-volume applications where speed and stability are required. When used with the PV624 Pressure Controller and DPI620G Calibrator, the IO624-LPA delivers fast, stable, and repeatable low-pressure calibration without manual pumping. Beyond this range, the PV624 seamlessly operates in hybrid mode, extending calibration capability up to 20bar (2MPa/300psi) while maintaining the same platform and workflow.
Key Features
● Automated low-pressure control: Fully automatic generation and control to ±500mbar (50kPa/7.25psi) when used with PV624 + DPI620G + PM620LP.
● Hybrid high‑pressure operation: Manual pressurisation with PV624 up to 20bar (2MPa/300psi), with automatic control during vent‑down when used with PV624 + DPI620G + PM620.
● Genii ecosystem: Works seamlessly with DPI620G, PV624, and PM620 series pressure modules, providing electrical, pressure, RTD, thermocouple, and HART calibration on one system.
● Protection for sensitive low-pressure devices: Automatic pump technology prevents accidental overpressure during delicate low-pressure tasks.
● All‑day battery performance: Rechargeable Li‑ion battery supports extended field and workshop operation.
