Bently Nevada 330101-38-49-20-02-05 is an 8mm diameter eddy current sensor probe belonging to the 3300 XL series, designed for high-precision vibration and displacement monitoring of industrial rotating machinery. Based on the principle of electromagnetic induction, the probe can realize non-contact measurement. The probe adopts a high-pressure stainless steel shell (protection level IP68), built-in constant temperature compensation circuit, can work stably in an ambient temperature of -40°C~+177°C, and effectively resists electromagnetic interference (compliant with EN 61326-3-1) through a double-shielded coaxial cable. It is widely used in shaft vibration, axial displacement and key phase measurement of equipment such as turbines, compressors, and motors, and is a core component for industrial equipment condition monitoring and predictive maintenance.
