Application Note: Why Charge Amplifiers Remain Essential in Aerospace Test Systems
Introduction Many aerospace test programs rely on charge-output piezoelectric accelerometers, force sensors, and dynamic pressure transducers because of their wide frequency response, rugged construction, and ability to capture rapidly changing events. These sensors generate extremely small electrical charge signals—often measured in picocoulombs (pC)—that are susceptible to cable capacitance effects, electrical noise, leakage currents, and environmental influences that can compromise measurement accuracy. Charge amplifiers address these challenges by converting the sensor’s high-impedance charge output into a stable, low impedance voltage signal suitable for transmission, recording, and analysis. By making measurements largely independent of cable capacitance while maintaining low noise, stable [...]
NUCLEAR HEAT EXCHANGER VIBRATION
Power plants, particularly nuclear power plants, require heat exchangers to cool down the primary working fluid for the power plant. Excessive vibration can lead to cracking and premature failure of the heat exchanger. Problem: A major power plant company approached MTI looking for a sensor that could measure vibration of a heat exchanger assembly that was immersed under water. Additionally, the water could reach 250 F and up to 220 PSI; the probe had to be sealed with a gland at a bulkhead feed through area. Solution: MTI developed a special fiber optic probe based on the MTI-2125H probe configuration. The [...]

Application Note: Accessing Digital Engine Data for Multi-Platform Aircraft Balancing with MTI PBS Systems
Introduction Modern aircraft engines are no longer dependent solely on discrete analog sensors for critical performance data. Increasingly, vibration amplitudes, phase information, and engine speed are transmitted digitally through aircraft data buses such as ARINC 429 and ARINC 664 Part 7 (AFDX). Yet in many MRO environments, balancing systems continue to rely on accelerometers and tachometer pickups—introducing additional setup time, cabling complexity, and potential variability in measurements. This disconnect between available digital data and traditional measurement approaches creates inefficiencies, particularly for facilities servicing multiple aircraft platforms. For organizations supporting a diverse fleet, the opportunity is clear: leverage the aircraft’s [...]
