786-500-D2 Low Frequency (Seismic) Vibration Sensors

Top exit, broadband high sensitivity, low frequency sensor, MIL-C-5015 connector,500 mV/g, ±5% sensitivity tolerance

About the 786-500-D2 Low Frequency (Seismic) Vibration Sensors

Top-exit broadband sensor is certified for usage in hazardous areas. The high-sensitivity accelerometer offers an interior sensing element capable of producing 500 mV/g outputting clear signals at low vibration levels. The low-end frequency response makes it ideal for slow-speed applications such as wind turbine generators and cooling towers. A high top-end frequency response offers clear signals for early bearing fault detection, gearbox wear, and other high-speed applications. The 786-500-D2 is classifed for usage in Class I Division 2/Zone 2 locations where ignitable gases, vapors or liquids are handled, processed or used but are not usually present during normal operation and can only escape through accidental rupture, breakdown or leaks.
