Accelerex RBA-500

Digitally-compatible frequency output Accelerometer

RBA-500

High Performance, Low cost Accelerometer

The Honeywell Accelerex RBA500 accelerometer is their frequency output sensor. 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.
