Description

Option 90 (9.0 meters system length, panel mount) and Option 05 (Multiple Approvals) specify this 3300 XL 50 mm Proximitor Sensor configuration — 330878-90-05.

While DIN mount configurations (Option 91) and 5.0-meter systems (Option 50 or 51) are available, this panel-mount, 9.0-meter system matches 330876 probes and 330877 extension cables for longer transmission distances. The Multiple Approvals selection allows installation in designated hazardous environments where compliance is required. The sensor utilizes advanced eddy-current technology to process displacement signals from a 50 mm probe, rendering it highly effective for differential expansion (DE) or rotor expansion (RX) measurements on steam turbine generators.

Features

  • System Length: Configured for a 9.0 m (29.5 ft) system length, providing compatibility with corresponding 50 mm probes and extension cables.
  • Mounting Style: Panel-mount physical design for secure attachment to mounting plates or internal enclosures.
  • Agency Approvals: Option 05 designates multiple global hazardous area certifications, including CSA, ATEX, and IECEx approvals.
  • Connection System: Built-in SpringLoc terminal strips provide fast, highly robust field connections without specialized tools.
  • RFI/EMI Immunity: Robust design elements shield signal integrity against nearby high-frequency radio interference.

Applications

  • Differential expansion (DE) measurement on utility steam turbine generators.
  • Rotor expansion (RX) monitoring to track thermal growth differentials.
  • Axial position and displacement tracking in heavy industrial rotating machinery.

Installation Guidelines

  • Mounting: Mount the Proximitor Sensor on a clean, flat surface using the standard panel-mount configuration holes.
  • Shield Grounding: Ensure the field wiring shield is connected to the monitor common ground and insulated at the Proximitor end to prevent ground loops.
  • Terminal Connection: Depress the SpringLoc lever, insert the stripped conductor (0.2 to 1.5 mm2), and release to secure. No special tools are needed.
  • Minimum Cable Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) for coaxial and triaxial system cables to prevent signal loss or conductor damage.
