Accelerometer test instrument 856A1357G05

for enginesaeronauticalportable

Overview
The 856A1357G05 Sensor Tester is a precision diagnostic instrument engineered for the CFM56-3 engine used on Boeing 737 Classic aircraft. It provides electrical signal simulation and measurement capabilities that enable maintenance teams to assess the condition of engine sensors (speed, temperature, vibration pickups) with clear diagnostic data.

Precision & Reliability in Engine Diagnostics
Accurate sensor readings are critical for engine control and flight safety. The 856A1357G05 simulates and measures electrical signals to verify sensor output and calibration against aerospace tolerances, allowing technicians to identify degradation or failures and avoid unnecessary part removals while ensuring dispatchability.

Key Features & Benefits

• Dedicated CFM56-3 compatibility: Interfaces with sensor architectures specific to CFM56-3 engines for relevant diagnostic signals.
• High-precision detection: Measurement functions designed to verify sensor health, signal integrity and calibration within required tolerances.
• Optimized troubleshooting: Streamlines fault isolation to reduce aircraft ground time on the flight line or in the engine shop.
• MRO-oriented design: Constructed for use in hangar and on-wing test scenarios to support maintenance workflows.
