Industry Applications for Vibration Monitoring
The 200 mV/mil scale factor and 80 mil range provide precise data for predictive maintenance. Its corrosion resistance to common industrial fluids makes it suitable for harsh environments like refineries and chemical plants.
Installation and Setup Guidance
Mount the probe with 3/8-24 threads into a suitable bracket or housing. Ensure the unthreaded length of 120 mm and overall case length of 5.2 in match the installation geometry. The total length of 0.5 metre (20 inches) with tolerance must be accounted for in cable routing. Connect using the miniature male coaxial connector. Verify the input power supply is within -17.5 Vdc to -26 Vdc at 12 mA maximum.
Maintenance and Reliability
Inspect the probe face and cable periodically for contamination or damage. The environmental limits allow operation from -30°F to +350°F for the probe. The system weight of 1.3 lbs simplifies handling. The probe is designed for long-term reliability in continuous monitoring applications.
