330100-90-00 | Bently Nevada Proximitor Sensor

Bently Nevada 330100 - 90 - 00 is an eddy current sensor belonging to the 3300 series produced by Bently Nevada Corporation, used in short-range sensor systems. The following is its relevant information:

Model meaning: 330100 is the basic model identification, "90" means the total cable length is 9.0 meters (29.5 feet), and "00" represents no other options such as special agency certification.

Working principle: Based on the eddy current effect, when the sensor probe is close to the metal surface to be measured, eddy currents will be generated on the metal surface. By detecting the change in the magnetic field generated by the eddy current, the gap change between the probe and the metal surface to be measured is converted into a proportional voltage signal, thereby realizing non-contact displacement measurement.

Technical parameters:

Power supply voltage: 24V DC.

Measurement range: Usually used with the 8mm eddy current probe of the 3300 series, the linear range is 0 to 2mm (0 to 80mil).

Output characteristics: The output voltage is proportional to the distance from the probe to the target conductive surface, with a proportionality factor of 200mV/mil (7.87mV/μm), that is, the output voltage changes by 200mV for every 1mil change in distance.

Temperature range: It can operate in a wide temperature range to ensure the accuracy and consistency of the output signal.

Product features:

Rugged and durable: The patented probe tip positioning molding method is used to make the connection between the probe tip and the probe body more solid; the probe cable adopts a patented cable positioning design with a tensile strength of 330N (75lbf), which can more reliably connect the probe cable and the probe tip.

Easy to install: Its physical packaging allows installation on high-density DIN rails, or traditional panel mounting, and the mounting base provides electrical isolation without the need for a separate isolation board.

Strong anti-interference ability: It is highly immune to radio frequency interference and can be installed in a fiberglass housing without the adverse effects of nearby radio frequency signals.

Application areas: Mainly used for vibration and position measurement applications of fluid dynamic bearing machines, as well as key phase and speed measurement applications. It can perform static (position) and dynamic (vibration) measurements. For example, in the condition monitoring of rotating mechanical equipment such as turbines, compressors, and pumps, it is used to measure radial vibration, axial displacement, speed and other parameters of the shaft, providing an important basis for equipment fault diagnosis and maintenance.
