Product Overview

The PR6423/10R-040 is a high-precision non-contact eddy current displacement sensor engineered for turbomachinery protection within Turbine Supervisory Instrumentation (TSI) systems. Operating on a contactless inductive measurement principle, this sensor measures shaft vibration, axial position, and eccentricity in high-speed rotating machinery. It outputs a proportional voltage signal that interfaces with machinery protection systems to assist in monitoring mechanical conditions and managing system downtime.

Features

  • Frictionless operation via a contactless inductive measurement principle
  • Ruggedized 8 mm diameter sensing tip constructed from ceramics and stainless steel
  • High-durability armored jacket designed to withstand physical stresses during conduit routing
  • Output signal compatibility with machinery protection systems for real-time analysis

Applications

  • Steam turbine shaft vibration and axial position monitoring
  • High-speed compressor eccentricity tracking
  • Gearbox asset protection in power plants, refineries, and industrial pumping stations

Installation Guidelines

  • Set the sensor at its electrical center during installation, which typically corresponds to -10 VDC for a standard converter, by monitoring the gap voltage with a voltmeter while adjusting the mounting thread.
  • Maintain a minimum clear radius of 15 mm around the sensing tip to prevent metallic objects from distorting the magnetic field and causing false readings.
  • Avoid routing the armored sensor cable parallel to high-voltage power lines, utilize dedicated instrument trays, and ground the cable armor exclusively at the machine housing to avoid noise induction from ground loops.

from ground loops.

FAQ

What is the recommended target material for calibration?
The device should be calibrated against 42CrMo4 steel or a similar ferromagnetic alloy to achieve standard linearity and accuracy.

Can the integrated 10-meter cable be altered in length during installation?
No, the cable length is an integral part of the tuned circuit. Modifying the cable will alter the system impedance and cause measurement errors.

What is the maximum pressure capability at the sensing face?
The sensor face is designed to withstand fluid pressures up to 10 bar (145 psi), making it suitable for pressurized oil environments.
