Key Challenges of Aircraft Landing Gear Testing Pressure Sensor Selection
Landing gear tests combine high shock, hydraulic pressure, fatigue cycles and temperature exposure. A sensor that works in a general hydraulic rig may not provide stable data in a landing gear drop test.
Shock Load
Landing Gear Shock Test Accelerometer Data Can Drift Under 10000g Impact
Drop and impact tests can expose sensors to instantaneous loads up to 10000g. General-purpose sensors may survive the first hit but still produce unstable output after repeated cycles.
Dabey response: overload capacity up to 150%FS, 10000-cycle shock calibration before shipment, and data deviation controlled to ≤0.03%FS.
Temperature Drift
Aircraft Landing Gear Testing Pressure Sensor Stability Across -55°C to 150°C
Cold-soak and high-temperature tests create a wide thermal span. Temperature drift can make pressure and shock data difficult to compare across test phases.
Dabey response: aerospace-grade MEMS silicon-sapphire process, temperature drift ≤0.01%FS/°C, suitable for -55°C to 180°C test environments.
Lead Time
KULITE Equivalent for Landing Gear Testing Without Long Imported-Brand Delivery
Use KULITE, PCB and DRUCK sensors often require 12 weeks or more. When a sensor fails during a qualification program, the test bench can stay idle.
Dabey response: standard models 2-4weeks, custom models are delivered in ≤10 weeks, and drop-in dimensions avoid test bench interface changes.
Traceability
Aerospace Calibration Traceability for Landing Gear Test Sensors
Landing gear test data must be traceable. Missing calibration documents or incomplete standard references can delay report approval.
Dabey response: each unit ships with a CNAS-accredited calibration certificate and documentation aligned with RTCA DO-160G and ASTM F3303 test requirements.

Proven Application in Commercial Aircraft Landing Gear Testing
Customer: Domestic Commercial Aircraft Supporting Test Institute
Test scenario: C919 landing gear drop fatigue test
Original issue: The test team used KULITE XCEL-100 pressure sensors. Delivery time reached 14 weeks, and replacement cost increased after repeated wear and tear.
Dabey solution: DBS-P200 pressure sensors and DBS-ACC-300 accelerometers were supplied with 100% parameter matching and no modification to the test bench interface.
Test Result
The system operated continuously for 1200 hours without sensor failure. Data deviation remained ≤0.03%FS, and the final procurement cost was reduced by 30%.

Frequently Asked Questions
Q1:What KULITE models can Dabey replace for landing gear pressure testing?
Our DBS-P200 series can directly replace KULITE XCEL-100, XTE-190 and other common models for landing gear testing, with fully matched parameters and no need to adjust the test system.
Q2:Do your accelerometers for landing gear shock test meet RTCA DO-160 standards?
Yes. Dabey aerospace-grade sensors are supplied with documents for RTCA DO-160G verification, CE and UL certification where applicable, and official certification reports for review.
Q3: How long is the delivery time for custom landing gear test sensors?
The delivery time for customized models is ≤2 weeks, and conventional models in stock can be shipped within 48 hours, which is 70% faster than typical imported-brand delivery cycles.
Q4:Can you provide calibration certificates that meet aerospace traceability requirements?
All products are shipped with a CNAS-accredited calibration certificate, which supports traceability requirements for aviation test programs.
