High-Precision Pressure Measurement Instrument for Drone and Aircraft Engine Systems



The ZYH-2 Military Aviation Sensor Pressure Meter is a precision-engineered instrument designed for accurate pressure measurement in demanding aerospace environments. Engineered specifically for aircraft engine monitoring, drone hydraulic systems, and critical Aviation Applications, this high-quality pressure meter provides reliable, real-time pressure data essential for system performance, safety monitoring, and preventive maintenance programs.
Manufactured with the same rigorous quality standards as our Military Metal Relay and Polarized Relay product lines, the ZYH-2 represents YM's commitment to producing measurement instruments that deliver exceptional accuracy and durability under extreme operational conditions.
Designed and tested to withstand extreme environmental conditions encountered in military aviation operations, including temperature extremes from -55°C to +125°C, high vibration environments, and shock loads up to 100g. The rugged construction maintains calibration integrity under conditions that would compromise commercial-grade instruments.
Features a precision-engineered analog dial with high-contrast markings, anti-parallax design, and optional illuminated display for readability in all lighting conditions. The display is optimized for quick, accurate reading even during high-vibration flight conditions.
Incorporates hermetic sealing techniques developed through our expertise in Metal Sealing Relay manufacturing. The multi-layer sealing system ensures protection against media leakage and environmental contaminants while maintaining measurement accuracy throughout the instrument's service life.
Weighing under 3 grams, the ZYH-2 provides essential pressure measurement capabilities without significant weight penalty—critical for aircraft and drone applications where every gram affects performance, range, and fuel efficiency.
With response times under 4 milliseconds, this pressure meter provides near-instantaneous pressure readings essential for real-time system monitoring and control in critical aviation systems.
Designed to operate accurately in electrically noisy aviation environments, complementing our PCB Signal Relay and Solid State Relay products in integrated electronic systems without measurement interference.
Utilizes a precision-formed, heat-treated Bourdon tube mechanism for reliable pressure measurement with minimal hysteresis and excellent repeatability over the instrument's service life.
Critical for monitoring oil pressure, fuel pressure, hydraulic pressure, and pneumatic system pressures in both turbine and piston aircraft engines. Provides essential data for engine management systems, performance monitoring, and preventive maintenance programs.
Essential for monitoring hydraulic pressure in flight control systems, landing gear, and payload mechanisms in military and commercial drones. The lightweight design preserves flight endurance while delivering critical operational data.
Monitors pressure in flight control hydraulic systems, landing gear systems, brake systems, and utility hydraulic systems in both military and commercial aircraft platforms.
Provides accurate cabin pressure and differential pressure measurement for passenger aircraft, ensuring passenger comfort and safety through accurate pressure control system monitoring.
Critical for fuel pressure monitoring in aircraft fuel systems, including engine feed systems, transfer systems, and refueling systems, ensuring proper fuel delivery and system safety.
Provides accurate pressure measurement for aircraft maintenance equipment, hydraulic test stands, and ground support systems during maintenance operations and system testing.
Provides accurate, real-time pressure data enabling early detection of system issues before they cause component failures or safety incidents, reducing operational risks and supporting regulatory compliance.
Extended service life (10,000+ cycles) and minimal calibration requirements lower total cost of ownership compared to pressure instruments requiring frequent replacement or recalibration.
Accurate pressure monitoring enables optimal system operation, reducing energy consumption, improving system performance, and extending component service life in critical aviation systems.
Standardized mounting and connection interfaces compatible with common aviation pressure systems reduce integration time and costs compared to custom measurement solutions.
The ZYH-2 Military Aviation Sensor Pressure Meter is designed and manufactured to meet or exceed the following standards:
All instruments include calibration certificates traceable to national standards, with optional NIST-traceable certification available. Materials are certified for aviation use with full traceability documentation.
The ZYH-2 is manufactured in YM's controlled-environment production facilities using precision CNC machining for critical components and automated assembly techniques. Our manufacturing process incorporates statistical process control to ensure consistent quality and performance across all production batches.
Every instrument undergoes rigorous testing and validation:
Our in-house calibration laboratory, maintained to ISO/IEC 17025 standards, features deadweight testers and digital pressure standards traceable to national measurement institutes. Regular proficiency testing ensures our calibration capabilities meet the highest industry standards.
Verify that the ZYH-2 pressure range, accuracy class, pressure connection, and media compatibility match your system requirements. Check temperature and vibration specifications against your operational environment.
Install the pressure meter in the designated location using appropriate mounting hardware. Ensure proper orientation (typically vertical) and accessibility for reading and maintenance.
Connect the pressure meter using appropriate thread sealant or sealing washers. Use proper torque values to avoid damaging the pressure port or compromising the seal.
Gradually pressurize the system while monitoring the pressure meter for proper operation. Check for leaks at the connection points.
After installation, verify calibration accuracy using a calibrated pressure source. Document installation calibration data for future reference and maintenance records.
Recommended calibration interval: 12 months for standard applications, 6 months for critical flight systems or harsh operating environments. All calibrations are documented with certificates traceable to national standards.
