Bently Nevada TDISECURE PN2155-40-01
TDISECURE PN:2155/40-01 is an explosion-proof electromagnetic proximity probe launched by Bently Nevada. Specifically designed for use in high-temperature, high-pressure, and potentially explosive environments (such as chemical, oil refining, and thermal power plants), this product measures the axial displacement of rotating machinery (e.g., steam turbines, compressors, pump shafts). It real-time calculates the gap between the rotor and the casing by sensing changes in the shaft’s magnetic field, and is widely used for monitoring the axial movement of rotor shafts, serving as one of the key protective monitoring devices.

Installation and Maintenance Recommendations
- Installation Positioning: The probe should be installed perpendicular to the rotor shaft, and the center of the probe should be concentric with the rotor axis to avoid errors caused by eccentricity.
- Connection Inspection: After installation, check whether the cable connections are firm to prevent poor contact due to vibration.
- Regular Calibration: It is recommended to perform zero calibration regularly to ensure measurement accuracy.
- Environmental Inspection: Regularly check whether the explosion-proof housing is damaged or rusted, and replace damaged parts in a timely manner to prevent potential safety hazards.
