Expert Questions & Answers
What type of output signal does this accelerometer provide?
It provides a standard IEPE (ICP®) voltage output signal, compatible with most data acquisition systems and vibration monitors.
Can the integral cable be repaired or replaced in the field?
No. The cable is hermetically sealed to the sensor body. If damaged, the entire unit must be returned for factory service or replacement.
What is the main advantage of the hermetic seal?
It prevents moisture ingress, allowing reliable operation in environments with high humidity, condensation, or where washdowns occur.
How do I power this sensor?
Use a constant current power source (typically 2-20 mA) with an 18-30 VDC supply. Most compatible conditioners or data collectors provide this.
From a reliability engineer’s experience, what ensures longest service life?
Ensure the mounting surface is clean, flat, and free of paint. Use the correct thread locker and torque to prevent loosening from vibration, which is a common failure point.
Is this sensor suitable for measuring low-frequency vibration?
Its lower frequency limit is 15 Hz (900 CPM). For very low-speed machinery (below 900 RPM), a different sensor with a lower frequency range is recommended.
What is the significance of the T4 temperature rating?
T4 means the sensor’s surface temperature will not exceed 135°C in operation, making it safe for use in hazardous areas with gases having an ignition temperature above that.
Can it be used with wireless vibration monitoring systems?
Yes, if the wireless node provides IEPE constant current power and accepts a voltage input signal within the sensor’s output range.
