• For a frequency output sensor, Honeywell produces the Accelerex RBA500 accelerometer. It is primarily used for tactical navigation applications, including tactical missile and 'smart bomb' programs. It's 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.
