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 [...]

Wireless Measurement of Very Small Gap Changes Inside Rotating Machinery
Solar, Semiconductor Measurement of Ungrounded Targets Thickness, Metrology Description Description This application note describes how to use capacitance for the non-contact, wireless measurement of very small gap changes (distances) between a device and a grounded target. It uses the textile industry as an example, but any industry that uses machinery with continuously rotating drums or motors can benefit from this approach to remote measurement. Capacitance is highly accurate and can support the use of probes that are wireless. In our example, a capacitive sensing system from MTI Instruments eliminated concerns about establishing and maintaining [...]
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 [...]
