Physical Dimensions: The length, width and height are 81.3mm × 61mm × 63.5mm, and the weight is 246g, which is compact and lightweight for easy installation.
Protection Level: Achieves an IP67 protection rating, with dustproof and waterproof capabilities to resist the erosion of industrial site pollutants.
Thread Specification: Adopts an M12 × 1.5 thread size, which facilitates quick and stable installation of the sensor.
High-Precision Measurement Guarantee: The output voltage has a strict linear correspondence with the gap change between the probe and the measured surface. The optimized circuit design reduces temperature drift, ensuring that the measurement data remains accurate even when the ambient temperature fluctuates.
Strong Anti-Interference Capability: Built-in filtering circuits and shielding structures can effectively suppress electromagnetic noise generated by equipment such as motors and frequency converters on industrial sites. This ensures the stability of output signals without being affected by external electromagnetic interference.
Seamless System Compatibility: It can be seamlessly integrated with Bently’s 3300 and 3500 series monitoring systems. It also matches 3300 XL 8mm eddy current probes and extension cables without the need for additional calibration during assembly and use.
Flexible Installation and Configuration: It provides optional extension cable lengths such as 5 meters and 9 meters to meet the wiring needs of different equipment installation spaces. The M12 × 1.5 thread design simplifies the installation process, and the compact size allows it to be installed in limited space.
Fault Safety Protection: Equipped with an output voltage overload protection design. When the sensor malfunctions, it can avoid invalid signal output, preventing false alarms or equipment damage caused by abnormal signals.
Application Scenarios
Petrochemical Industry: It is used for condition monitoring of centrifugal compressors in catalytic cracking units of refineries. It can capture early faults such as bearing wear and rotor imbalance in a timely manner, significantly reducing unplanned shutdown time of equipment and lowering annual maintenance costs for enterprises.
Power Energy Industry: It is applied to the monitoring system of steam turbines in coal-fired power plants and nuclear power plants. It forms a detection combination with 3300 XL probes to monitor the axial displacement of the turbine shaft system. When the displacement exceeds the threshold, it triggers an alarm and links to shutdown operations to avoid collision accidents between the rotor and the stator.
Metallurgical and Mining Industry: Installed on jaw crushers and other equipment in mineral processing plants, it monitors the shaft vibration signals of the equipment. It can identify fault modes such as gear wear and bearing oil shortage through spectrum analysis, providing early warnings for equipment maintenance and avoiding production losses caused by sudden equipment failures.
Marine Industry: Deployed in the propulsion systems of LNG transport ships, it adapts to the wide temperature environment of -40℃ to 55℃ during ship navigation. Its IP67 protection level and anti-vibration design ensure stable signal output even in the bumpy navigation state, safeguarding the safe operation of the ship’s power system.
General Industrial Equipment: Suitable for key power equipment that requires preventive maintenance, including generators, water pumps and fans. It monitors the operating status of these devices in real time, helps optimize operating parameters, and improves the efficiency and service life of the equipment.
