330850-51-05 | BENTLY NEVADA 3300 XL 25 mm Proximitor Sensor

The Bently Nevada 330850-51-05 is the 3300 XL 25 mm Proximitor Sensor, designed for non-contact vibration measurement and proximity sensing in industrial applications. It offers advanced features that make it suitable for high-density installations or traditional panel-mount configurations.

Key Features:

Thin Design: Enables easy mounting in high-density DIN-rail setups or standard panel-mount configurations.
RFI/EMI Immunity: Enhanced resistance to radio frequency and electromagnetic interference, ensuring reliable performance even in environments with high-frequency radio signals. It also meets European CE mark approvals without needing special mounting conditions.
SpringLoc Terminal Strips: Facilitate fast, tool-free field wiring connections, enhancing the ease and robustness of installation.
Factory Calibration: The sensor is calibrated by default to AISI 4140 steel, but can be recalibrated for other materials upon request, offering flexibility for different application needs.

Specifications:

Electrical:

Sensor Input: Accepts a non-contacting 3300 XL 25 mm proximity probe and extension cable.
