よくある質問 (FAQ)
-
What is the response time / the transducer?
The device has a frequency response up to 5 kHz, allowing it to capture rapid casing movements in real-time. -
Can the sensor operate in high vibration environments?
Yes, the robust stainless steel housing and internal design allow stable operation in high-vibration settings. -
What type / signal conditioning is required?
The transducer outputs a differential LVDT signal that can be interfaced with standard Bently Nevada monitoring modules. -
Is the output linear across the full range?
Yes, linearity is ±0.5% / full scale. -
Can this transducer be used with non-Bently Nevada systems?
Technically yes, but compatibility must be verified for signal conditioning and voltage requirements. -
How resistant is the assembly to temperature variations?
It operates reliably from -40°C to 120°C without degradation in performance. -
What is the recommended mounting orientation?
Typically flanged or surface-mounted, aligned per the casing’s expansion axis. -
How does the sensor handle electrical noise?
Differential LVDT output minimizes susceptibility to electromagnetic interference. -
Can the transducer measure dynamic and static expansions simultaneously?
Yes, it captures both quasi-static casing changes and dynamic vibration effects. -
