Overview
High-Performance Third Axis
Banner’s QM30VT3 uses a digital MEMS sensor for collecting vibration data. The ultra-low noise density on all three axes ensures accurate data no matter the sensor orientation to prevent maintenance decisions from being made because of the bad trending of false data. Most 3-axis MEMS sensors only offer a low noise profile on two axes with the third axis (typically the Z or Vertical Radial Axis) having two to three times the noise density, causing that third axis to have inaccurate data. This inaccurate data leads to maintenance decisions made without a true fault present.
Configuring High-Frequency Enveloping (HFE) or Demodulation Mode
High-frequency enveloping (HFE), or demodulation, is a separate measurement type and signal processing technique that is very sensitive to high-frequency impacts and friction.
HFE can be useful for diagnosing bearing defects, lubrication issues, cavitation, and gear faults. These types of faults produce very low energy impacts/forces that can make them difficult to detect in their early stages with standard vibration measurements because they can be drowned out by the machine’s fundamental forces. HFE mode trends the values to detect early faults so maintenance can occur before a downtime event occurs. When paired with a lower FMax setting, the sample frequency still remains at maximum but the sensor takes a much longer sample. This data is used to trend early defects on slow-speed assets that would normally require a special ultrasound accelerometer. When using HFE mode, set Fmax to 3 or 4 for the longer 2.4-second or 4.8-second sample times. To enable HFE mode, set register 42059 value to 0 for OFF or 1 for ON.
Adjustable FMax Settings
The QM30VT3 has optional settings to increase the frequency resolution of the measurement through the adjustable FMax settings.
Adjusting the FMax setting allows users to control the trade-off between frequency resolution, bandwidth, and measurement duration. Lower FMax settings provide finer frequency resolution but reduce the total bandwidth and increase the measurement time, whereas higher FMax settings broaden the frequency range but may sacrifice resolution. FMax is critical in vibration analysis because it determines the sensor’s capability to detect and characterize different vibration frequencies, which is essential for diagnosing machinery health, identifying faults, and optimizing maintenance strategies. High-frequency measurements are only available at the default FMax of 5300 Hz. These options are changed in register 42058. FMax Options include:
- = 5300 Hz (3.29Hz resolution, 300 ms sample duration)
- = 2650 Hz (1.65Hz resolution, 610 ms sample duration)
- = 1300 Hz (0.82Hz resolution, 1.215 seconds sample duration)
- = 650 Hz (0.41Hz resolution, 2.43 seconds sample duration)
- = 325 Hz (0.21Hz resolution, 4.86 seconds sample duration)
VIBE-IQ Integration
The QM30VT3 server uses Banner’s VIBE-IQ® machine learning algorithm to make vibration data analysis much easier.
VIBE-IQ automatically generates a baseline of an asset, generates warning and alarm thresholds, and sets alert flags to get immediate feedback of potential issues. This greatly simplifies the process of gaining valuable insight into the health of an asset. More details about the register map and configuration of VIBE-IQ within the QM30VT3 can be found in the QM30VT3 VIBE-IQ Technical Note found on our website at www.bannerengineering.com

Scalar Data Glossary
The following list defines many of the available parameters on the Banner QM30VT3 Vibration and Temperature Sensor.
- Velocity
Measures a moving or vibrating mass’s speed.
Velocity is used in the lower frequency part of the vibration measurement to indicate many types of vibration faults, such as unbalance, misalignment, soft foot, looseness, eccentricity, etc. Trending velocity over time with continuous monitoring can indicate these faults early. - High-Frequency Acceleration
Useful metric for early high-frequency fault detection when trended for bearing faults, cavitation, gear mesh, rotor rubs, lubrication issues, etc. - Crest Factor
Peak Acceleration / RMS Acceleration. This unitless ratio defines how a signal peaks and is used to predict an impact. Increasing crest factor tends to be an early indicator of bearing faults. - Kurtosis
Unitless statistical measure of the tailedness of a normal distribution of the data.
Kurtosis represents the probability or frequency of values that are extremely high or low compared to the mean. Values around three (3) indicate moderate outlier frequency (normal distribution); less than three (3) indicates lower outlier frequency, and above three (3) indicates higher outlier frequency. - Peak Velocity/Acceleration Frequency Component
Provides the frequency where the highest peak of either velocity or acceleration occurred within the specified bandwidth. Can be useful for detecting motor fundamental frequencies or fault frequencies as they appear. - Asset Run Flag
Uses the measured acceleration data to determine if the asset is running or is offline.
Magnitude
√(X² + Y² + Z²); Provides the magnitude of all three vectors and is specifically used for high-frequency acceleration measurement where the direction is less important and the trend of the overall value of the data can be used in a single point.
Installing the QM30VT3 Sensor
The vibration sensors have an X, Y, and Z axis indicated on the face of the sensor. Typically, in vibration analysis, the three axes are referred to as Axial (in line with the shaft of the asset), Horizontal Radial (parallel to the ground), Vertical Radial (perpendicular to the ground).
Not every application is identical so not every orientation will be the same. It is important to document the direction in which each axis is installed for labeling and diagnostic purposes.
An example install is to mount the sensor at the top center of a horizontally mounted motor with the X axis (parallel with the sensor cable) in line with the motor shaft or to mount the sensor with the Y axis (perpendicular to the sensor cable) perpendicular to the shaft in the horizontal radial axis and the Z axis (through plane of the sensor) going into or through the motor in the vertical radial axis.
For the best results, install the sensor as close to the motor bearing as possible. If this is not possible, install the sensor on a surface that is in rigid connection with the vibration characteristics of the motor.
Using a cover shroud or other flexible mounting location may result in a reduced accuracy or reduced ability to detect certain vibration characteristics. After determining the sensor direction and location, mount the sensor for the best possible vibration sensing accuracy.
| Mounting Options | QM30 Housing Type | Description |
| BWA-QM30-FTAL (included with the aluminum housing model) | Aluminum | When available, directly mounting the bracket to the motor using an 1/4-28 × 1/2-inch screw provides a rigid surface with the highest sensor accuracy and frequency response. This mounting option offers flexibility for future sensor and bracket movement.
Another mounting option is to use an epoxy to adhere the bracket to the motor. Banner recommends using an epoxy designed for accelerometer mounting, such as Loctite Depend 330 and 7388 activator. Epoxying a bracket to a motor provides a permanent installation of the bracket to which the sensor can be attached. This more rigid mounting solution ensures some of the best sensor accuracy and frequency response, but is not flexible for future adjustments. A third option is to use the included thermally conductive adhesive tape. This often provides a more than sufficient mounting type but does introduce some additional flex that reduces accuracy. |
| BWA-QM30-FTSS (included with the stainless steel housing model) | Stainless steel | |
| BWA-QM30-CEAL (curved bracket epoxied to the motor) |
Aluminum |
This lightweight aluminum bracket provides a close connection to the motor with ridges to sit on curved surfaces and ensure a tight fit. The bracket is epoxied to the motor and the sensor is screwed into the bracket. |
| BWA-QM30-FMSS (flat magnet bracket) | Aluminum and stainless steel | Gives a solid, strong, and adjustable mount to a motor, but with a motor’s curved surface it may not provide the best connection if the motor is too small for the magnet to get a full connection with the motor housing. Magnet mounts are susceptible to accident rotation or a change in the sensor location if an outside force bumps or moves the sensor. This can lead to a change in sensor information that differs from the time-trended data from the previous location.The bracket is stainless steel and the magnet insert is neodymium. |
| BWA-QM30-CMAL (curved surface magnet bracket) | Aluminum and stainless steel | Gives a solid, strong, and adjustable mount to a motor, intended for use when the flat magnetic bracket does not make a good connection with the motor’s surface.
Magnet mounts are susceptible to accidental rotation or change in the sensor location if an outside force bumps or moves the sensor. This can lead to a change in the sensor information that differs from the time-trended data from the previous location. The bracket is aluminum and the magnet insert is samarium-cobalt. |
| BWA-QM30-FSALR (robust quick- release bracket) | Aluminum | This larger aluminum bracket mounts to the motor with a 1/4-28 × 1/2-inch screw to provide a rigid connection to the motor.
