—— Product Information ——

The CE 680 M411 444-680-000-411 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 4 mA constant current supply. The output signal has a sensitivity of 100 mV/g.
Thanks to the accelerometer's isolated ground and Faraday shield, no ground loops or frame voltage are present to disturb the measurement.
The CE 680 M411 444-680-000-411 shows extremely low noise levels and exceptional bias voltage stability at elevated temperatures.

FEATURES
• Designed for medium temperature industrial applications (-55°C to +120°C)
• Shear mode operation, therefore no output due to thermal transients
• 2-pole low-pass filter for resonance suppression
• Hermetically sealed for harsh environments
• Ground isolated from case and connected to a Faraday shield
• Bias voltage stability at elevated temperatures
