Product Description

The 3300/48-01-01-01-00 is a high-precision thermal growth monitoring module designed to interface with 3300 XL NSv proximity transducers. Unlike standard LVDT-based expansion monitors, this module translates NSv sensor feedback into actionable data for machinery protection and supervisory control. It is ideal for turbine supervisory instrumentation (TSI) applications where space constraints or specialized sensor requirements exist.

By continuously tracking casing displacement relative to the foundation, the 3300/48-01-01-01-00 helps prevent mechanical misalignment, vibration, and structural stress in rotating machinery.

Application Scenarios

  • High-precision thermal monitoring of steam turbines and specialized rotating machinery

  • Integration with 3300 XL NSv sensors already used for vibration or thrust monitoring

  • Suitable for confined spaces where LVDTs are impractical

  • Supports turbine supervisory instrumentation (TSI) in power generation plants and industrial facilities

Comparison & Functional FAQ

How does this NSv version differ from standard 3300/48?

  • Standard 3300/48 modules typically interface with LVDTs for long-stroke measurements.

  • The 3300/48-01-01-01-00 is tuned for short-range, high-precision NSv proximity sensors, ideal for confined installations.

What happens if the sensor signal is lost?

  • The module performs internal self-diagnostics.

  • Loss of signal or cable failure triggers the "OK" LED to extinguish, and the 4–20 mA output drops below 3.6 mA to alert the control system of a loop integrity issue.
