M88280 Module of IRD8800 Series is meant for Vibration Monitoring of Generator End Winding. The sensitivity of the module can be adjusted based on the input high temperature sensor and Charge Amplifier. The Sensitivity for a Charge Amplifier with an output proportional to Vibration Acceleration can be between 0.1 mV/g and 999.9 mV/g. However, the most popular sensitivity in use are 150 mV/g and 250 mV/g
