Find clear answers to the most common questions about vibration monitoring technology and related solutions.
IEPE accelerometers include built-in electronics that convert the sensor’s high-impedance charge signal into a low-impedance voltage output, making them easy to use with standard signal conditioners and long cable runs.
Charge-output (PE) accelerometers produce a raw charge signal and require an external charge amplifier, but they are often preferred for very high temperatures, radiation environments, or where maximum measurement accuracy is required.
4–20 mA vibration sensors are designed for continuous machine monitoring rather than detailed vibration analysis.
They output a standard industrial current loop signal that connects directly to PLCs, SCADA systems, and condition monitoring hardware.
They are typically used for pump, motor, and fan protection where simple trending and alarm thresholds are required.
IEPE accelerometers are powered through the same two wires that carry the output signal.
A constant current source (typically 2–20 mA at around 18–28 V) is supplied by a signal conditioner or data acquisition system.This simplifies wiring and allows the sensor to be used with standard coaxial or twisted-pair cables.
The way a sensor is mounted has a significant impact on accuracy and frequency response.
Stud mounting provides the best high-frequency performance and repeatability, while adhesive and magnetic mounts are more convenient but reduce usable bandwidth.
Correct mounting ensures that the sensor accurately follows the motion of the structure being measured.
Every accelerometer has a mechanical resonance determined by its internal seismic mass and suspension system. When the sensor is mounted to a structure or connected to long cables, the effective system dynamics can shift, altering the frequency response.
1. Mass Loading:
Mounting a sensor on a lightweight or thin structure adds the sensor’s mass (ms) to the system, lowering the natural frequency of the measured structure. The combined resonant frequency can be approximated by:
where:
Even small sensors can significantly affect lightweight or precision structures, introducing measurement errors at high frequencies.
2. Cable Capacitance (for charge-mode accelerometers):
Charge-output sensors are sensitive to cable capacitance (Cc), which effectively forms a high-pass filter with the amplifier input. The cutoff frequency is approximately:
where:
Long cables increase Cc, lowering fc, reducing sensitivity to low-frequency vibrations, and potentially introducing phase lag in dynamic measurements.
Implication:
For high-fidelity measurements, especially in modal analysis, low-frequency monitoring, or broadband high-g applications, engineers must consider both mass loading and cable effects. Ignoring these factors can lead to amplitude attenuation, frequency shifts, and distorted vibration spectra.
With the variety of vibration sensors available, choosing the right one for your application can be difficult.
