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.

330703-00-100-10-11-CN | Bently Nevada | 3300 XL 11 mm Proximity Probes
Technical Overview
The Bently Nevada 330703-00-100-10-11-CN is an 11 mm eddy current proximity probe designed for non-contact displacement and vibration measurement on rotating machinery. It functions as a core component of the 3300 XL 11 mm Transducer System, which also includes a matched extension cable and a 3300 XL 11 mm Proximitor Sensor. The system operates on the eddy current principle, where the Proximitor Sensor emits a high-frequency radio frequency (RF) signal through the probe and extension cable. This signal radiates from the probe tip, creating an 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 impedance. The Proximitor Sensor demodulates this signal to produce a DC voltage directly proportional to the gap between the probe tip and the target surface. This analog voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 series, for real-time analysis of radial vibration, axial position, and shaft speed. The 330703-00-100-10-11-CN features a robust stainless steel case and a chemically resistant Polyphenylene Sulfide (PPS) tip, ensuring reliability in harsh industrial environments.

Technical FAQ
Q: What systems is the 330703-00-100-10-11-CN compatible with?
A: The 330703-00-100-10-11-CN probe must be used as part of a complete Bently Nevada 3300 XL 11 mm Transducer System. This requires a matching 3300 XL 11 mm Proximitor Sensor (e.g., part number 330780) and a 3300 XL 11 mm extension cable. It is not interchangeable with components from 5 mm or 8 mm transducer systems, as the scale factor and linear range are different. The complete transducer system provides a voltage output compatible with Bently Nevada monitoring systems, including the 3500 and 3300 series, as well as third-party PLCs, DCS, and data acquisition systems designed to accept a 3-wire, -24 Vdc powered eddy current probe input.
Q: What are the installation requirements?
A: Proper installation is critical for accurate measurements. The probe must be mounted perpendicular to the observed shaft surface using a rigid bracket. The target area on the shaft must be smooth (typically 0.4 to 0.8 µm / 16 to 32 µin Ra), free of chrome or other non-conductive plating, and clear of any residual magnetism or electrical runout. The probe must be gapped correctly by adjusting its distance to the shaft until the Proximitor Sensor output voltage is at the center of the linear range, typically -10.0 Vdc. The probe case locknut should be torqued to the specified value to prevent loosening. The integral cable and any extension cable should be secured to avoid strain on the connectors and routed away from high-voltage power cables to minimize interference.
