The Bently Nevada 31000-16-10-15-030-03-02 is a specialized proximity probe housing designed to physically protect a proximity probe and its integral cable within harsh industrial environments. Its primary function is to provide a secure, environmentally sealed mounting point on rotating machinery for acquiring critical vibration and position data. The housing is constructed from 304 Stainless Steel, offering robust protection against physical impact and corrosion. This specific configuration, 31000-16-10-15-030-03-02, features a 3/4-14 NPT external mounting thread for direct installation into a machine case. Internally, it accommodates a Bently Nevada 3300 XL 8 mm or 3300 5 mm probe, which is positioned by a 1.0-inch stinger (probe sleeve). The housing facilitates the signal path from the probe tip to the Bently Nevada 3500 Monitoring System. The probe, connected via an extension cable to a Proximitor Sensor, generates a high-frequency RF signal. The resulting eddy current field is used to measure the distance to the observed conductive target. The Proximitor Sensor conditions this signal into a calibrated DC voltage proportional to the gap, which is then transmitted to a 3500/42M Proximitor/Seismic Monitor module for analysis, alarming, and machinery protection.

The Bently Nevada 21504-00-32-10-02 is a 3300 NSv series proximity vibration probe, a fundamental component of an eddy current transducer system designed for non-contact displacement and vibration measurement on rotating machinery. Its primary function is to measure the distance (gap) between the probe tip and a conductive target material, typically a machine shaft. The probe operates by generating a high-frequency radio frequency (RF) field from its tip coil. When brought near the conductive target, this field induces eddy currents on the target's surface. These eddy currents alter the impedance of the probe's coil system. This change in impedance is detected by an associated Proximitor Sensor, which demodulates the signal into a voltage directly proportional to the probe-to-target gap. This analog voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 Machinery Protection System, for real-time analysis, trending, and alarming. The 21504-00-32-10-02 is constructed with a stainless steel case for durability in industrial environments and is specifically configured with a 320 mm case length and a 1.0-meter integral cable.
