Detailed Product Description

Honeywell-AC RBA500 Accelerometer

Digitally compatible frequency output sensor

 

For a frequency output sensor, Honeywell produces the Accelerex RBA500 accelerometer. It is primarily used to supplement GPS navigation systems. It is a good choice where frequency output, high-g, small size, low power, and light weight are necessary.

The acceleration is measured as a function of the frequency difference between two vibrating quartz beams. The output of the Accelerex accelerometer is also thermally compensated through the use of an internal temperature sensor and Honeywell-supplied coefficients; when integrated over time, delta Velocity is directly provided to the user's system.

 

 

Principle of quartz flexible accelerometer:

 

When the external acceleration is input, the pendulum will leave the equilibrium position under the action of inertia force. At this time, the differential capacitance value composed of the upper and lower surface of the pendulum plate and the upper and lower torque end face will change, and this electrical signal is output to the servo circuit through the terminal. The amplified current signal is output to the coil, and the pendulum is restored to the equilibrium position by push-pull action using the ampere force of the energized wire in the magnetic field. When the deflection Angle of the pendulum is very small, the current is approximately linear with the input acceleration. At this time, the input acceleration can be obtained by detecting the current.
