Bently Nevada 24765-02-01｜Case Expansion Transducer Systems｜
Technical Specifications
Operating Temperature: –40 ℃ to +121 ℃ (industrial-grade operating range)
Output Signal: DC voltage signal, linearly proportional to displacement
Power Supply: Provided by Bently Nevada 3500/20M or compatible monitoring modules
Core Functions and Features
Accurate Shell Expansion Measurement
Provides real-time measurement of casing thermal expansion and contraction during equipment startup, shutdown, and load changes. Effectively prevents faults such as rotor-to-stator contact and bearing overload, enhancing overall machinery protection.
Spring-Reset Self-Calibration Design
Equipped with a built-in spring reset mechanism. After cooling, the sensor automatically returns to its reference position without manual readjustment, improving maintenance efficiency. Particularly suitable for peak-shaving units and applications with frequent start–stop cycles.
High Signal Stability and Reliability
The DC LVDT features a robust anti-electromagnetic interference design, ensuring stable and accurate signal output in high-voltage industrial environments. The output can be directly interfaced with monitoring systems such as Bently Nevada 3500/20M, simplifying system integration.
