Barfield 304-00006 Digital Pressure Gauge, 0 to 200 PSI

The Barfield 304-00006 digital pressure gauge is used to measure and verify aircraft system pressures during maintenance, inspection, and troubleshooting. It provides precise digital readings that support accurate testing of pressure-based aircraft components. This level of accuracy is especially important when validating system performance against manufacturer specifications.

This digital pressure gauge is designed for use with the Barfield 2311FA Pressure Tester, where it functions as the master pressure gauge for test operations. It installs directly at the tester’s gauge adapter location and integrates seamlessly into existing Barfield pressure testing setups. Compatibility with the 2311FA allows technicians to perform controlled and repeatable pressure tests.

Digital pressure gauges provide more precise readings and higher resolution than traditional analog gauges. The Barfield 304-00006 reduces interpretation errors by displaying pressure values numerically rather than relying on needle position. This improves consistency, especially during inspections that require tight pressure tolerances.

The 304-00006 digital pressure gauge measures pressures from 0 to 200 PSI, making it suitable for a wide range of aircraft pressure testing tasks. This range aligns well with common airframe and engine system checks. It allows technicians to perform both low-pressure verification and higher-pressure validation using a single gauge.

This gauge provides accuracy within ±0.25% of full scale, supporting precise pressure verification during aircraft maintenance. High accuracy is essential when testing pressure transmitters, switches, and warning systems. Reliable readings help ensure systems operate safely within approved limits.

During troubleshooting, the digital pressure gauge enables technicians to monitor pressure changes in real-time. Small fluctuations or pressure drops are easier to detect with a digital display. This helps identify leaks, faulty components, or incorrect system behavior more efficiently.

Yes, routine calibration is required to maintain accuracy and compliance with aviation maintenance standards. Calibration intervals typically follow shop procedures or regulatory guidelines. Keeping the gauge properly calibrated ensures reliable test results and supports quality assurance programs.

The compact and rugged design of the Barfield 304-00006 makes it suitable for both shop environments and field maintenance applications. When installed on the 2311FA pressure tester, it provides portable testing capability without sacrificing accuracy. This flexibility supports line maintenance, inspections, and troubleshooting tasks.

The gauge supports the testing of pressure-based aircraft systems, including engine pressure transmitters, warning switches, and airframe pressure circuits. It is commonly used during functional checks and leak testing procedures. Accurate pressure measurement is critical for confirming proper system operation before returning to service.

A digital display reduces time spent interpreting readings and documenting results. Technicians can quickly confirm whether a system meets required pressure values. This improves workflow efficiency and minimizes the risk of misreading measurements during inspections.

Yes, the gauge is designed for professional aviation maintenance environments where accuracy and repeatability are required. When properly calibrated and installed, it supports compliance with maintenance manuals and inspection procedures. Its use aligns with best practices for aircraft pressure testing.

Routine care includes protecting the gauge from physical damage, verifying calibration status, and ensuring proper installation on the pressure tester. The manufacturer does not recommend user-performed internal repairs. If issues arise, service should be performed by approved repair facilities.

Accurate pressure testing helps confirm that aircraft systems respond correctly under operating conditions. By providing dependable measurements, the Barfield 304-00006 helps prevent undetected pressure faults. This contributes directly to safe aircraft operation and regulatory compliance.
