Features:
- Bently Nevada 0.300-inch Radiation-Resistant Close Range Probe
- Radiation-resistant close-range probe, 3/8-24 UNF thread, unarmored
- Critical vibration and displacement monitoring in nuclear power facilities and other high-gamma radiation environments
Like an "electronic antenna" for the equipment, it is specifically deployed in critical machine components to monitor radial vibration, axial displacement, and shaft eccentricity in real time. By continuously monitoring physical deformation at the micron level, it can help maintenance personnel detect problems such as bearing wear, rotor imbalance, or misalignment early, thereby preventing unplanned downtime due to mechanical failure.
This probe model plays a central role in industrial monitoring, providing precise signal transmission and safety interlock protection. According to its coding, the "96" in the middle typically indicates that the probe comes with a 9.6-meter (or 96-inch, depending on the product line definition) integrated extension cable, making it ideal for heavy industrial applications with long-span, wide-distance cabling, allowing signals to be directly input to the preamplifier without the need for additional intermediate connectors.
The 83607-00-96-05-02 Bently Nevada SENSOR UNIT may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 83607-00-96-05-02 probe primarily measures gap changes based on the principle of electromagnetic induction eddy currents. During system operation, the accompanying preamplifier (proximity sensor) supplies high-frequency alternating current to the coil at the top of the probe, thereby generating a high-frequency alternating electromagnetic field on the probe's end face.
When the surface of the measured metal shaft changes position due to vibration or displacement and approaches this magnetic field, reverse eddy currents are induced on the metal shaft surface, absorbing and weakening the electromagnetic field energy generated by the probe. This energy loss causes a corresponding change in the internal resistance of the probe coil.
The preamplifier precisely captures and modulates this impedance change, converting it into a linear voltage signal proportional to the physical distance between the probe and the shaft surface. Based on this signal, the main system can accurately calculate the real-time dynamic amplitude and displacement value of the shaft.
Extended Probe: The 9.6-inch probe length is optimized for deep holes or thick-walled housings, suitable for situations where shorter probes cannot reach the target axis.
Radiation Hardening: Utilizing ceramic-metal seals and advanced inorganic insulation materials, it resists performance degradation caused by high-dose cumulative gamma radiation.
System Components: Can be integrated with a three-piece system including this probe, a radiation-hardened extension cable, and the 330280 proximity sensor.
