Main Functions

  1. Excites 25 mm eddy‑current probe, converts gap‑variation between probe tip and metallic shaft target into proportional analog voltage signal.
  2. Deliver real‑time displacement data for turbine differential‑expansion, shaft axial‑position monitoring.
  3. Detect probe cable open‑circuit and short‑circuit faults, send fault status to TSI monitor rack.
  4. Transfer gap‑proportional voltage signal to 3500 monitor module for alarm/trip logic processing.
  5. Cooperate with probe and extension cable to complete large‑range non‑contact position measurement for rotating‑machinery.
  6. Provide measured variable to upper‑level DCS/SCADA system via TSI rack analog output or communication interface.
  7. Support continuous long‑term on‑line monitoring for critical turbo‑machinery.
  8. Serve as signal‑conditioning proximitor unit of Bently Nevada 3300‑XL 25 mm proximity transducer system.
