Bently Nevada 21000-16-05-00-050-04-02 Sensor Proximity

Bently Nevada 21000 - 16 - 05 - 00 - 050 - 04 - 02 is an eddy current proximity sensor produced by Bently Nevada, which is used to measure parameters such as shaft vibration and shaft displacement of rotating machinery. The following is a detailed introduction to it:

Probe type: The code "16" indicates that the 3300 XL 8mm probe is used. This probe has high accuracy and stability, can accurately measure the tiny displacement and vibration of the shaft, and is suitable for monitoring a variety of rotating machinery.

Cable length: "05" represents the probe cable length of 0.5 meters (20 inches). Shorter cable length can reduce interference during signal transmission, improve measurement accuracy, and also facilitate wiring when installation space is limited.

Mounting accessories: "00" indicates a non-support adapter. If the installation structure of the equipment can directly meet the installation requirements of the sensor and does not require additional supports to adjust the position and angle of the sensor, this configuration can be selected to reduce costs and simplify the installation process.

Probe penetration: "050" means the probe penetration is 5.0 inches. Probe penetration refers to the depth that the probe can penetrate into the vicinity of the object being measured. This dimension needs to be determined according to the specific installation space and the object being measured to ensure that the probe can accurately measure the parameters of the target position.

Connector type: "04" represents the configuration of a 3/4 - 14 NPT plug. This connector type has good sealing and mechanical strength, can ensure the reliable connection between the sensor and the external circuit, and is easy to install and disassemble, suitable for various industrial environments.

Mounting thread: "02" means the mounting thread is 3/4 - 14 NPT. This standard thread specification is easy to connect with the corresponding mounting components, ensuring that the sensor is firmly installed and can work stably in a vibrating environment.

Working principle: Bentley 3300 series proximity sensor system uses the eddy current principle to measure displacement. The sensor generates a high-frequency magnetic field. When the metal object to be measured is close to the probe, eddy currents will be generated on the surface of the object. The magnetic field generated by the eddy current will react to the magnetic field of the sensor, causing the inductance of the sensor to change. By measuring this change in inductance, a negative voltage proportional to the distance between the target and the probe tip can be obtained, thereby realizing the measurement of shaft displacement and vibration.

Application scenario: This sensor is mainly used to measure parameters such as shaft vibration and shaft displacement of rotating machinery, providing important data support for equipment status monitoring and fault diagnosis. It is widely used in large-scale rotating machinery and equipment in the power, petrochemical, metallurgical and other industries, such as steam turbines, generators, compressors, etc. It can monitor the operating status of the equipment in real time, discover potential fault hazards in time, and ensure the safe and stable operation of the equipment.
