Description
The APP Automated Pressure Gauge Calibration System (APGCS) tests the linearity of analog pressure gauges from atmospheric pressure to 60,000 PSI. Highly accurate master gauges ensure precise calibration of up to nine slave gauges per iteration. The APGCS also allows fatigue testing of the gauges. The APGCS results in less down time and fewer overall costs.
Software
The APGCS is completely microprocessor controlled and fully automated, thereby eliminating operator error. Easy-to-use APGCS software runs with Windows '98 and higher. The APGCS software allows user-determined pressure steps, holding times, pressurization rates, and calibration at specific target pressures. Throughout the calibration process, the software provides useful reports and data, including a pressure versus time graph, a Pass/Fail rating for each slave gauge, and a percent error. Upon completion of the process, a report is generated containing this information.
Applications
The APGCS is utilized in manufacturing and industrial environments where pressure gauges are used or manufactured. The APGCS is unique in its ability to calibrate any make of pressure gauge, regardless of manufacturer. Moreover, the APGCS is adaptable to any calibration procedure currently in use. Rather than ask our customers to change their calibration procedure, we customize our instrument to fit that procedure.

Hardware: Pneumatic System (Applications up to 5,000 PSI)
The Automated Pressure Gauge Calibration System - Pneumatic System comprises a motorized pressure generator, air-operated hydraulic pump, HEISE gauges, HEISE master gauges, motorized valves, air-operated valves, regulator, and manifold. The APGCS - Pneumatic System uses the motorized pressure generator or the air-operated hydraulic pump to generate and hold high pressure for calibrating the slave gauges. Three HEISE gauges (more accurate than the slave gauges) are used to monitor and control the system pressure, and serve as the reference for calibrating the slave gauges. All the testing data are stored in a data file compatible with a customized Excel data sheet.
The APGCS - Pneumatic System has two control modes: multi-target pressure control and pressurization rate control mode. (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.

Hardware: Hydraulic System (Application up to 60,000 psi)
The Automated Pressure Gauge Calibration System - Hydraulic System comprises a motorized pressure generator, pressure transducer, internal master gauges, motorized valves, reservoir, and manifold. The APGCS - Hydraulic System uses the motorized pressure generator to generate and hold high pressure for the slave gauges being calibrated. Three master gauges (more accurate than the slave gauges) monitor and control the system pressure, and serve as the reference for calibrating the slave gauges. All the testing data are stored in a data file compatible with a customized Excel data sheet.
