Product catalog summary

Overview
An aero engine is a complex machine requiring precise measurement of various physical parameters at high speeds to assess performance. Gantner Instruments' Q.series data acquisition system is designed for testing a wide range of engines, from APUs to large rocket engines, meeting the demands of modern engine test cells.

Key Features

Adaptability: The system supports a wide variety of I/O modules, allowing for a scalable measurement platform suitable for development, production, and overhaul testing.
High Uptime: The HOT SWAP feature enables system expansion and modification without shutdown, ensuring continuous operation.
Data Management: The system can create up to 20 configurable data loggers, minimizing data storage overhead by adjusting scan rates according to test requirements.
Integration: Open standard support facilitates integration into networked systems via REST API or fieldbus protocols like EtherCAT and Modbus TCP.

Measurement Capabilities

Temperature: Features built-in disturbance depression and adaptive linearization for precise measurement, with triple galvanic isolation and cold-junction compensation.
Vibration: Uses IEPE sensors and real-time FFTs for accurate vibration analysis, crucial for preventing engine self-destruction at high speeds.
Pressure: Includes a universal measurement module for pressure transmitters, essential for calculating engine efficiency and thrust.
Thrust: Utilizes strain gage beams or load cells for accurate thrust measurement, minimizing signal drift and ensuring repeatability.
Speed: Employs the Chronos method for accurate frequency measurement across a wide range of engine speeds.
Fuel Flow: Capable of high-speed measurement to capture rapid transients, aiding in fuel efficiency assessment.

Conclusion
The Q.series offers a modular solution for measurement technology needs, adaptable to various testing requirements with a wide range of modules and packaging options.

For Turbine Engines, Rocket Engines, Ramjets and APUs Data Acquisition System for Engine Test Cells An aero engine is a very complex machine. Many physical parameters are measured at relatively high speeds to accurately characterize engine performance. Gantner Instruments’ Q.series data acquisition system is designed for a wide range of engine testing, from APUs to large rocket engines. To meet the growing requirements of engine test cells, data acquisition systems must be able to record, display and process up to 2000 different parameters, varying from pressures, flow rates, vibrations and temperatures....

■ Temperature Temperature is the single most important measurement to determine engine performance. The Q.series system features built-in disturbance depression and adaptive linearization for precise temperature measurement. Triple galvanic isolation up to 1200 V, Intrinsic Safety barrier compatibility and stable cold-junction compensation ensure high-accuracy even in the harshest environments. ■ Vibration At high speeds, small vibrations can cause an engine to self-destruct. Typically, IEPE sensors are used to measure the vibration signature of rotating parts. The Q.series features per-channel...
