2. Installation
2.1 Receiving Inspection
Inspect the components of the your order as soon as you receive them for any
shipping damage. Keep all shipping forms and invoices. If you discover any
shipping damage, file a claim with the carrier and submit a copy to Bently Nevada
LLC. Include all model numbers and serial numbers with the claim. We will either
repair or replace damaged parts according to the terms and conditions of the
sale.
The velocity sensor is shipped in a protective package and the connector will be
protected with a plastic cap. The Velomitor® Sensor is a sensitive instrument and
these precautions help to prevent damage during shipping.
Application Alert:
Leave the protective cap on the connector until the
final field wiring connection is made. This will prevent foreign debris
from contaminating the connector possibly causing performance issues.
2.2 Installing the Transducer
2.2.1 Positioning the Sensor
For optimum performance and accurate measurements, place the velocity sensor
at a position on the machine casing that is most responsive to vibration. Proper
placement is often dependent on the application. Bently Nevada offers Machinery
Diagnostic Services, which can help determine the best place to mount the sensor
for your application.
2.2.2 Mounting
Follow these steps to install the Velomitor® Sensor:
Applies to the 330500 and 330530 Velomitor® Sensors:
Step 1.
Verify that the ambient temperature and the temperature of the
installation surface are within the temperature rating of the transducer.
Step 2.
Verify that the mounting site is flat, clean, and dry. The sensor requires a
flat surface at least 1.25 inches in diameter. For the best results the roughness of
the mounting surface should be no more than 32 micro-inch RMS and its flatness
should be at least .0008 inches Total Indicator Reading (TIR).
Step 3.
Determine if the sensor requires a protective housing for the sensor. We
recommend using the Velocity Transducer Housing Assembly (P/N 21128) if
maintenance operations will expose the Velomitor® Sensor or its connecting
cable to possible physical damage or if the sensor will operate in an environment
containing solvents, corrosives, or excessive moisture.
