Pressure calibration pressure controller Additel ADT793

digitalIP20precision

Overview
The Additel ADT793 pressure controller combines advanced control/measurement technology, a modular design and user-friendly maintenance features in a single industrial instrument. The ADT793 provides pressure control up to 1,000 bar and supports automated production, test and calibration workflows. It accepts a dual-range ADT151 pressure module and an optional barometric module to cover a wide pressure range quickly.

Functional details and applications
Application: ADT793
Quick-change pressure modules (30 s): ADT151 modules can be installed or replaced quickly by opening the cabinet door; five module ranges are available (1000 bar, 700 bar, 400 bar, 350 bar or 200 bar) with multiple accuracy levels to meet application requirements.
External reservoir support: Design supports a contamination prevention method where the controller draws only clean fluid each cycle and purges potentially contaminated fluid externally to avoid cross-contamination between the controller and units under test (UUT).
Contamination Prevention System (CPS): Optional feature that facilitates maintenance by automatically draining fluids and performing purges between cycles to reduce contaminant introduction and improve durability and reliability.
