Resonating Beam Accelerometer - RBA500

Robust Design & Superior Reliability

 

For a frequency output sensor, Honeywell produces the Accelerex® RBA500 accelerometer. It's a good choice where frequency output, high, 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.

Features

• Frequency output for direct interface to digital electronics
• Low price
• High-g capability
• Very compact design
• Integral 2 fastener mounting flange
• Low power consumption
• Hermetically sealed case
• Internal temperature sensor for thermal compensation
