Tronair H-1394 CPU Pressure Gauge, 0 to 15 PSI

The Tronair H-1394 CPU pressure gauge is calibrated to measure pressures from 0 to 15 pounds per square inch (PSI), making it ideal for low-pressure applications such as cabin pressurization systems. This range enables technicians to accurately monitor small pressure changes during testing and service procedures. It is not intended for high-pressure hydraulic systems or applications outside its rated range.

This gauge is usually mounted in the control or test panel of compatible Tronair cabin pressurization units to display real-time system pressure. It connects to the pressurization circuit through a threaded port and provides a visual reference during setup, testing, and troubleshooting. Correct installation ensures reliable pressure readings and supports safe operation.

Accurate pressure readings are critical when testing cabin pressurization because even small deviations can affect aircraft performance and occupant comfort at altitude. The H-1394 gauge provides dependable readings within its 0 to 15 PSI range, enabling maintenance teams to verify that systems are responding correctly. Inaccurate gauges can lead to missed faults or improper adjustments.

While the H-1394 is designed for Tronair cabin pressurization units, it may be compatible with other equipment that uses similar 0 to 15 PSI fittings and pressure philosophies. Compatibility depends on thread type, mounting style, and pressure connection configuration. If you’re unsure, reach out to PJi’s aviation specialists to confirm fitment with non-Tronair gear.

Yes. Like all precision pressure instruments, the Tronair H-1394 should be calibrated periodically to ensure measurement accuracy. Calibration intervals vary by usage frequency and regulatory requirements, but are often annual or per organizational policy. Calibrating the gauge against known standards helps maintain confidence in test results.

Calibration is typically performed using a precision pressure calibrator or dead-weight tester that applies known pressures within the gauge’s range. The technician compares the applied pressure to the gauge reading and adjusts the instrument as needed. Some gauges have an internal adjustment screw or require calibration only at a service facility.

The Tronair H-1394 CPU Pressure Gauge features NIST-traceable calibration, ensuring accurate, reliable pressure readings that meet industry and regulatory standards.

The gauge is built for use in aircraft ground support environments and is constructed to withstand typical shop conditions. However, like all mechanical pressure gauges, it can be affected by vibration, shock, or moisture if mishandled. Protecting the gauge from excessive impact and corrosive environments extends its service life.
