Description

The Emerson PR6423/002-030 CON021 is an eddy current sensor and signal converter system designed for critical turbomachinery applications such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans to measure radial and axial shaft dynamic displacement, position, eccentricity, and speed. The PR6423/002-030 non-contact sensor operates with a PEEK (Polyether Ether Ketone) tip, stainless steel case, and PTFE cable. The system integrates with the CON021 eddy current signal converter to convert probe displacement signals into standardized voltage outputs.

Features

  • Non-contact eddy current measurement for dynamic displacement, position, eccentricity, and speed.
  • Linear measurement range of 2 mm (80 mils) with 0.5 mm (20 mils) initial air gap.
  • High dynamic response featuring frequency range from 0 to 20000 Hz (-3 dB) and rise time <15 microseconds.
  • Signal converter housed in durable LMgSi 0.5 F22 aluminum alloy enclosure.
  • Self-locking Lemo-Plug transducer connection combined with screw terminal type signal and power connections.

Applications

  • Steam turbines
  • Gas turbines
  • Hydro turbines
  • Compressors
  • Gearboxes
  • Industrial pumps and fans
