Installing the Sensor

The vibration sensors have an X and Z axis indication on the face of the sensor. The Z axis

goes in a plane through the sensor while the X is parallel to the sensor.

•

Install the X axis in line with the shaft of the motor or axially.

•

Install the Z axis to go into or through the motor or radial.

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 vibration

characteristics of the motor. Using a cover shroud or other flexible mounting location may

result in 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

Applicable QM Models

Description

BWA-BK-014

QM30VT1, QM30VT2

Flat bracket with direct screw mount to motor and sensor

When available, directly mounting the bracket to the motor using an M4 × 0.7 bolt provides a rigid

surface with the highest sensor accuracy and frequency response. This mounting option offers

flexibility for future sensor and bracket movement.

BWA-BK-012

QM30VT2-SS-9M

BWA-BK-014

QM30VT1, QM30VT2

Flat bracket epoxied to motor and sensor screwed to bracket

Recommend 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.

BWA-BK-012

QM30VT2-SS-9M

BWA-BK-013

QM30VT1, QM30VT2,

QM30VT2-SS-9M

Flat magnet bracket

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 accidently rotation or change in 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.

Thermally Conductive

Adhesive tape

QM30VT1, QM30VT2,

QM30VT2-SS-9M

Often provides a more than sufficient mounting type but does introduce some additional flex that

reduces accuracy

Holding Registers

By default, data is sampled every five seconds. Use the Sensor Configuration Tool to adjust the sensor's sample rate if a different

value is needed. Aliased register addresses are user configurable. Aliased addressed registers are sequenced to be read with one

single Modbus read. Temperature values outside of the operating range of the device are forced to the maximum or minimum

values.
