Automated Pressure Holding System

The APP Automated Pressure Holding System (APHT) is designed to generate, maintain, and control pressure at user-defined levels for extended durations. The system operates from atmospheric pressure up to 5,000 psi in pneumatic configurations and up to 60,000 psi in hydraulic configurations.

Automated Pressure Holding System

Overview

The APP Automated Pressure Holding System (APHT) is designed to generate, maintain, and control pressure at user-defined levels for extended durations. The system operates from atmospheric pressure up to 5,000 psi in pneumatic configurations and up to 60,000 psi in hydraulic configurations. The APHT is fully automated and microprocessor-controlled, allowing users to define pressurization rates, target pressures, dwell times, and holding durations. The system is ideal for leak testing, pressure stability testing, and component validation applications.

  • Highly accurate pressure transducer monitors system pressure and provides feedback.
  • User-defined multiple target pressures, holding times, dwell times, and pressurization rates.
  • Tests can be performed under elevated temperature to simulate actual operating conditions(optional).
  • Multi-level, fail-safe system provides over-pressurization protection operating conditions (optional).
  • Windows-based software for automated control, data acquisition, and reporting.
  • Compatible with Windows ’98 and higher.
  • Real-time graphical display of pressure and system performance.
  • Multiple pressure outlet ports available.
  • Automatic pressure generator refill for high volume situations.
  • Multiple pressure generator systems for continuous and multi-axis pressurization (optional).
  • Customized report formats available.
  • Minimal maintenance required.
