Bently Nevada 330500-02-00 Velomitor Piezo-velocity Sensor
The Bently Nevada 330500-02-00 is a high-performance Velomitor sensor featuring a solid-state piezoelectric design for absolute vibration measurement. Encased in stainless steel, it offers omnidirectional mounting and maintenance-free operation for critical rotating machinery.
Product Overview
The Bently Nevada 330500-02-00 belongs to the specialized Velomitor series, designed to capture absolute casing vibration in rotating machinery. Unlike traditional moving-coil velocity transducers, this sensor utilizes piezoelectric technology combined with internal integration electronics. This solid-state architecture converts acceleration into a velocity signal directly within the sensor housing. By removing internal moving parts, the device eliminates the mechanical wear and friction typically associated with older sensor designs, which results in a more stable and maintenance-free vibration monitoring solution.
Core Functions and Capabilities
- Omnidirectional InstallationBecause the sensor lacks a mechanical spring-mass system, engineers can mount the 330500-02-00 at any orientation. Whether installed vertically, horizontally, or at an inverted angle, the transducer maintains its specified accuracy and performance without requiring recalibration or specialized mounting hardware.
- Advanced Signal ProcessingThe integrated electronics process the high-frequency raw data into a clean velocity output. This capability allows the sensor to monitor a broad range of machine faults, including unbalance, misalignment, and structural looseness, providing maintenance teams with actionable data for predictive maintenance programs.
- Enhanced ReliabilityThe hermetically sealed 316L stainless steel housing protects the internal circuitry from harsh industrial pollutants, moisture, and corrosive vapors. Consequently, the sensor performs reliably in extreme environments found in power plants, refineries, and chemical processing facilities.
- System CompatibilityThe 330500-02-00 interfaces seamlessly with Bently Nevada 3500 and 2300 monitoring systems. It provides a standard 2-wire connection that simplifies field wiring while maintaining high signal-to-noise ratios over long cable distances.

330192-00-28-05-00 | Bently Nevada | 3300 XL 8 mm ETR Proximity Probes
Technical Overview
The Bently Nevada 330192-00-28-05-00 is an 8 mm Extended Temperature Range (ETR) proximity probe component of the 3300 XL Proximity Transducer System. Its primary function is to perform non-contact measurement of relative displacement on rotating and reciprocating machinery. The probe operates on an eddy current principle. When paired with a 3300 XL extension cable and Proximitor Sensor, it forms a tuned oscillator circuit that emits a high-frequency radio frequency (RF) field from the probe tip. This field induces eddy currents on the surface of the observed conductive target, typically a machine shaft. The interaction between the RF field and the eddy currents results in a change in the oscillator's amplitude, which is directly proportional to the gap between the probe tip and the target. The Proximitor Sensor demodulates this RF signal into a precise DC voltage. This voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 Series, where it is processed to provide critical measurements including radial vibration, axial position (thrust), and rotational speed (when used in a Keyphasor configuration). The 330192-00-28-05-00 is constructed with a Polyphenylene Sulfide (PPS) tip and a stainless steel body, ensuring robust performance in high-temperature industrial environments.

330102-00-60-10-01-05 | Bently Nevada | 3300 XL 8 mm Proximity Probes
Technical Overview
The Bently Nevada 330102-00-60-10-01-05 is an 8 mm reverse-mount eddy current proximity probe designed for non-contact measurement of vibration and displacement. It functions as a core component of the 3300 XL 8 mm Proximity Transducer System, which also includes an extension cable and a Proximitor Sensor. The probe operates by having the Proximitor Sensor generate a high-frequency radio frequency (RF) signal, which is transmitted through the extension cable and radiated from the probe's tip into a small electromagnetic field. When a conductive target, such as a machine shaft, enters this field, eddy currents are induced on its surface. These currents create a secondary magnetic field that opposes the primary field, causing a measurable change in the RF signal's amplitude. This change is directly proportional to the gap between the probe tip and the target surface. The Proximitor Sensor demodulates this signal, converting it into a DC voltage that accurately represents the physical distance. This conditioned voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500, for real-time analysis of radial vibration, axial position, and shaft speed.

A: As a reverse-mount probe, the 330102-00-60-10-01-05 is installed from inside the machine housing, with the probe body extending outward. A clearance hole must be drilled through the machine case to accommodate the 8 mm probe tip. The target area on the observed shaft must be smooth, free of surface defects, and have a minimum diameter of 10.7 mm (0.42 in) to ensure measurement accuracy. The probe's gap should be set to the center of its linear range, typically corresponding to -10.0 Vdc. The ClickLoc connector must be tightened to the specified torque to ensure a secure, environmentally sealed connection. Cable routing must avoid areas of extreme heat, physical abrasion, and proximity to high-voltage power lines to maintain signal integrity.
