Pipeline Testing
Pipeline Testing Customer Case The customer wants to test pipelines for corrosion and cracks. They intend to use a small robot which they can send into the pipeline. This robot's purpose is to test the pipe by ultrasound and magnetic field for cracks, corrosion and other damage. The customer is using 2 different types of transducers, one for ultrasound and one for the magnetic field. They are sending a pulse with a magnetic field generator, capturing the received signal, rotating the transducer 1/2 degree and then sending another pulse and capturing signal again. After a complete 360 degree rotation, [...]

Plasma Coating of Airplane Parts
Plasma Coating of Airplane Parts Customer Case The customer produces plasma coating for airplane parts. They need to count the number of plasma particles on these parts so that they can adjust the plasma torch to be less or more powerful in order to obtain the required thickness of plasma coating. Using a particle detector, they are able to measure temperature, speed and quantity of particles. These parameters are used as feedback to control the plasma coating process. GaGe Case Solution The customer requires a scope card that has both high-resolution and a fast sampling rate. At the time [...]
Gas Turbine Monitoring
Gas Turbine Monitoring Customer Case A customer who designs and develops turbo-machinery uses automated data-acquisition and reduction routines. The complete system can sequentially scan up to 144 pressures, 40 electrical signals, and 50 temperatures. It can also acquire and analyze dynamic pressure/vibration signals as well as the scanned steady-state data. They do precise pneumatic traversing for high-performance radial-flow stages. Using a computer-controlled data-acquisition system, the detailed internal pressures and temperatures can be acquired and processed. Laboratory data files are generated, which can be directly used to process the impeller-cover static pressure data. The data can also be automatically processed [...]

Avionics Bus Monitoring
Avionics Bus Monitoring Customer Case The requirement is to monitor anomalies on an avionics bus that controls systems aboard spacecrafts. The customer will know typical rise times, and therefore, will look for anomalous high-voltage pulses that may occur due to sunspots or cosmic rays. An A/D card with at least 12-bits of vertical resolution is required to capture anomalous glitches for characterization. The required sampling speed is 50 KHz, on two simultaneous channels that monitor two bus lines. The input signal bandwidth is typically 4 KHz. The customer would like to write his own data acquisition application programs in [...]
