The CE 680 M511 is an all-purpose vibration sensor designed for use in harsh industrial machinery environments. It uses the industry standard 2-wire voltage transmission technique with a constant current supply. The output signal has a sensitivity of 100 mV/g.

Thanks to the accelerometer's isolated ground and internal shield, no ground loops or frame voltage are present to disturb the measurement. The CE 680 M511 shows extremely low noise levels and exceptional bias voltage stability at elevated temperatures.

Note: Unless otherwise stated, all values listed are typical values, referenced at +23°C, 24 VDC supply, 6 mA constant current and 120 Hz
