Frequently Asked Questions (FAQs)
-
What is the difference between 330100-90-02 and other 3300 Proximitor models?
The “-90-02” suffix usually specifies cable length compatibility and certain factory-configured options tailored to installation needs. -
Is the 330100-90-02 sensor backward compatible with older Bently Nevada monitoring systems?
Yes, it is compatible with legacy 3300, 3500, and selected customized systems. -
What type of proximity probes does it work with?
It is typically used with Bently Nevada 3300 XL 5mm and 8mm probes and associated extension cables. -
Does it require field calibration during installation?
Only a basic verification of sensitivity and gap voltage is recommended; full recalibration is usually not necessary unless specified. -
How is the sensor powered?
It draws -24 Vdc power supplied directly by the associated monitoring or rack system. -
Can it operate in explosive or hazardous environments?
It can, provided it is installed with appropriate hazardous area-rated enclosures and certifications in place. -
What is the main output signal format?
The sensor outputs an analog voltage proportional to the measured distance. -
How often should the system be checked for accuracy?
An annual inspection is recommended for critical machines; otherwise, condition-based verification is sufficient. -
Can the sensor survive exposure to oil mist or light contaminants?
Yes, its epoxy-coated enclosure protects it against common industrial contaminants. -
Does it offer diagnostics if the probe connection fails?
The 3300 monitoring system can detect open or shorted probes based on the signal from the Proximitor Sensor.
