The 86517 Accelerometer Interface Module is a component in accelerometer- based transducer systems commonly used for vibration monitoring of aeroderivative gas generators and gas turbines. The interface module is designed for use with the Bently Nevada 3300 series 3300/95 Filter Module/Vibration Monitor and can also be used with specially modified 3300 monitors such as the 3300/15 and 3300/25.

The accelerometer interface module performs the following functions:
1. Converts a charge input from the accelerometer to a voltage acceleration
signal.
2. Scales the voltage signal to 10 mV/g peak (1.02 mV/m/s2 pk).
3. Buffers the acceleration signal so that it can be connected to
instrumentation over long cable lengths.
4. Bandpass filters the acceleration signal using a 12th order filter with
corner frequencies determined by option BB.
5. Integrates the filtered acceleration signal to a velocity signal with a
sensitivity of 100 mV/in/s pk (3.94 mV/mm/s pk).
6. Buffers the velocity signal so that it can be connected to monitoring
instruments over long cable lengths. The velocity signal is typically used to
monitor machines.
