Product Overview

The Bently Nevada 88984-01 functions as a high-precision Proximitor Sensor within the Bently Nevada Proximity Transducer System. This module converts the raw impedance changes from an eddy current proximity probe into a linear voltage signal. It provides the essential interface for monitoring both static parameters (axial position) and dynamic parameters (radial vibration) on rotating machinery. We supply this unit as 100% Brand New and Original in Factory Packing, ensuring your 3300 or 3500 monitoring racks receive accurate, conditioned data for critical machinery protection.

Engineering Advantages

High-Accuracy Displacement Tracking: The 88984-01 utilizes advanced eddy current technology to achieve non-contact measurement. This eliminates mechanical friction and enables the sensor to detect sub-micron shaft movements at high rotational speeds.
Stable DC Performance: Unlike velocity or acceleration sensors, this Proximitor maintains accuracy down to 0 Hz. This allows it to monitor "Slow Roll" data and static axial thrust position, which are vital for identifying thermal expansion and rotor-to-stator clearances.
Superior Noise Immunity: Bently Nevada engineers this module with robust signal conditioning circuitry to reject electromagnetic interference (EMI). This ensures reliable vibration data even when installed near high-power motors or large variable speed drives.
Wide Thermal Range Compatibility: The module operates consistently in temperatures ranging from –35°C to +100°C. This industrial durability allows for installation in unprotected field housings near steam turbines and hot process machinery.
Flexible Installation Geometry: The compact 88984-01 module supports multiple cable length configurations (up to 9 meters total). This flexibility permits the mounting of the Proximitor in accessible junction boxes while the probe remains deep within the machine housing.

FAQs

Is the 88984-01 compatible with the 3500 series monitoring rack?

Yes. The 88984-01 outputs a standard conditioned voltage signal that integrates seamlessly with the 3500/40, 3500/42, and other vibration monitor modules within the 3500 system.
Does this part number include the proximity probe or extension cable?

No. The 88984-01 is the Proximitor Sensor module only. You must order the proximity probe (e.g., 3300 XL 8mm) and the extension cable separately to complete the transducer loop.
How do I verify the scale factor for my installation?

The 88984-01 typically provides a scale factor of –200 mV/mil. To maintain this accuracy, you must ensure the total length of the probe and extension cable matches the specific calibration (usually 5m or 9m) marked on the Proximitor label.
What is the condition of the unit upon delivery?

We guarantee that every 88984-01 we ship is Brand New and Original. The unit arrives in its original factory-sealed anti-static packaging, ensuring zero-hour reliability for your machinery protection system.
