Capacitance Sensors Track Brake Rotor Thickness Variation
Capacitance Sensors Track Brake Rotor Thickness Variation Automotive, Aviation/Aerospace Brake Rotor Testing & Manufacturing Displacement, Amplitude Description [Application Note 51018] Today’s cars and trucks offer unprecedented fuel efficiencies and handling characteristics – thanks, in part, to vehicle lightweighting. Applied to all vehicle components, lightweighting lowers stress and strain to improve mileage and boost overall performance. In keeping with this trend, today’s brake rotors are thinner and lighter than those of just a few years ago. In addition, many feature cooling vents to further improve performance. These changes, however, reduce available [...]

Signal Generator Tests Charge Amplifier Gain, Frequency Response
Testing Charge Amplifier Gain and Frequency Response with a Signal Generator Aviation/Aerospace, Industrial, Power Generation, Research & Development Charge Amplifier Gain and Frequency Response Testing Amplitude (Acceleration, Vibration, Pressure) Description [Application Note 40518] Piezoelectric transducers produce small electrical charges in response to pressure. Their sensitivity, ruggedness, and stability at high temperatures make them an essential building block of many accelerometers and pressure sensors. Applications include turbine vibration measurement (accelerometers) and combustion dynamics monitoring (pressure sensors). Typically, the high-impedance charge output produced by a piezoelectric transducer must be conditioned and amplified [...]

These turbine sections feature separate shafts that produce unique tachometer signals. Gas turbine engines have multiple rotating sections generally referred to as the low pressure compressor (N1) and the high pressure compressor (N2). These turbine sections have separate shafts that produce unique tach [...]
Capacitance Probes Measure Gaps in Rotating Environments
Capacitance Probes Measure Gaps in Rotating Environments Textiles, Industrial Optimizing Performance of Rotating Cylinders Gap Description [Application Note 72518] Sensor environments are not always ideal. Across the various Gap sensor applications conditions may vary drastically. Some setups may have requirements of miniaturization, and others of wireless signal propagation. In rotating environments where cables cannot go, often there is a need for both. Problem Traditional sensing solutions can’t be used in environments requiring wireless propagation such as inside a rotating body. In these situations, the size and power requirements restrict the [...]
Monitor Roller Gaps and Parallelism
Monitor Roller Gaps and Parallelism Industrial Printing, Calendering, Crushing Gap Easy Roller Gap Measurement Ensures Calendering Success Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement. Figure 1: Calender Rollers where consistent gap across the rollers are vital [...]
