Enhanced Automated Pressure Control
Description
The APP Enhanced Automated Pressure Control System (EAPCS) is designed to provide fast, precise pressure generation and control. From atmospheric pressure to 60,000 PSI, the EAPCS generates large volume, high pressure outputs in significantly reduced time. The EAPCS is microprocessor controlled and fully automated, thereby allowing user-defined multiple target pressures, holding times, and pressurization rates.
Software
Easy-to-use EAPCS software runs with Windows '98 and higher. Throughout the pressure control process, this software provides useful reports and data, including a real-time graphical display of pressure versus time. Upon termination of the pressurization process, data such as pressure, corresponding time, and motor speed can be downloaded to Excel for further analysis. Advanced Pressure Products also has the capability to customize the software to produce reports and data required for a specific application.
Applications
The EAPCS is specially designed for large volume, high-pressure applications, including:
- Battery Cell Burst Tests
- Air Bag Inflator Tests
- High Pressure Chamber Fatigue Tests
- Multi-Gauge Tests Calibration
- Supercritical Fluid Extration

Hardware
The Enhanced Automated Pressure Control System is comprised of a motorized pressure generator and hydraulic pump. Compressed air, processed through an automated regulator, drives the hydraulic pump, resulting in large volume, high-pressure working fluid. Upon approaching the target pressure, control is passed from the hydraulic pump to the motorized pump for improved precision.
The EAPCS has two control modes: multi-target pressure control and pressurization rate control. (Control algorithms are based on PID control.) Multi-target pressure control allows the operator to reach the targeted pressure quickly and smoothly, while minimizing overshoot. Additionally, multi-target control holds the designated pressure for a specified length of time. The pressurization rate control provides operator control of the pressurization rate at which the target is approached.
