FBA11DC-6 is a type of aerospace component manufactured by Polygone Technologies, Inc. It is a dual-channel contactless accelerometer designed to measure dynamic motion in the form of acceleration, velocity, and displacement. It is typically used for applications such as measuring aircraft vibration, flight-dynamic control, and turbine engine testing. This article will review the application field and working principle of the FBA11DC-6.

Application Field

The FBA11DC-6 provides high-precision, real-time dynamic motion measurement. Due to its small size and light weight, it can be installed in various position such as fuselage interior and wing locations. Its resolution and accuracy is suitable for aircrafts, helicopters, unmanned aerial vehicles, business jets, and commercial airliners. It can be used to measure acceleration, airspeed, roll/pitch rate, and altitude changes.

In addition, the FBA11DC-6 can be used in commercial aircraft engines as turbine flowmeters. It can be utilized to measure the mass airflow rate of the compressor and turbine sections for post-flight analysis. Such data can provide valuable performance insights, thus helping to identify engine performance trends over an extended period.

Apart from aerospace applications, the FBA11DC-6 can also be used for a variety of industrial applications such as heavy machinery vibration testing, to monitor the operation of industrial processes, and for brake system analysis. In addition, it can be used in automotive applications such as evaluating automotive suspensions, performing ESC (Electronic Stability Control) tests, and checking ride comfort levels.

Working Principle

The FBA11DC-6 is based on the principle of electromagnetic induction. It consists of a dual-channel transducer that converts mechanical motion into an electrical signal. There are two channels of the transducer that can independently measure acceleration, velocity, and displacement in either direction.

The device works by converting motion into an electrical signal via the two channels of inductive sensing. Each channel contains two coils arranged orthogonally, with one positioned stationary, the other moving in response to acceleration, velocity, or displacement in the measured direction.

A differential output voltage is then produced between the two channels. This is proportional to the magnetic flux density differential between the two coils and thus, to the acceleration, velocity, or displacement. By measuring this difference in voltage, the device is capable of low-noise onboard sensing and reading of dynamic motion.

Conclusion

The FBA11DC-6 is a dual-channel contactless accelerometer designed for measuring dynamic motion. It is suitable for a variety of aerospace and industrial applications, and can measure acceleration, airspeed, roll/pitch rate, and altitude changes. It works by converting motion into an electrical signal via two channels of inductive sensing, which produces a differential output voltage proportional to the acceleration, velocity, or displacement in the measured direction.
