Information

Overview Manuals Technical notes Product Applications Pre-Installation Check & Site Prep

Features:

  • Non-contact measurementof static and dynamic shaftdisplacement
  • Axial and radial shaftdisplacement (position)
  • Shaft eccentricity
  • Shaft vibration (motion)
  • Meets international standards,DIN 45670, ISO 10817-1 andAPI 670
The PR 6423 is a non-contact eddycurrent transducer with a ruggedconstruction and designed forextremely critical turbomachineryapplications such as steam,gas, compressor and hydroturbomachinery, blowers and fans.The purpose of a displacementprobe is to measure position orshaft movement without contactingthe measured surface – the rotor.In the case of sleeve bearingmachines, the shaft is separatedfrom the bearing material by athin film of oil. The oil acts asa dampener and therefore thevibration and position of the shaftare not transmitted through thebearing to the bearing case.

The PR6423/018-140 CON021 EPRO 8mm Eddy Current Sensor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The use of case vibration sensorsis discouraged for monitoringsleeve bearing machines since thevibration produced by shaft motionor position is greatly attenuatedthrough the bearing oil film.The ideal method of monitoringshaft position and motion is bymounting a non-contact eddysensor through the bearing, orinside the bearing, measuringthe shaft motion and positiondirectly. The PR 6423 is commonlyused to measure vibration ofmachine shafts, eccentricity, thrust(axial displacement), differentialexpansion, valve position, and airgaps 
  • Turbines: Steam, gas, and hydro turbines where high thermal stability is required
  • Compressors: Axial and centrifugal compressors susceptible to heavy structural loads
  • Industrial Gearboxes: Heavy-duty reduction and speed-increaser gearboxes
  • Pumps and Fans: Large-scale utility pumps, cooling tower fans, and blowers
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Verify Target Area: Ensure the target shaft area is completely free of scratches, tool marks, or rust. Surface defects introduce false mechanical runout errors into your vibration data.Confirm Materials: Verify the system is calibrated for your specific shaft steel type. Standard Emerson systems are factory-calibrated for 42CrMo4 or AISI 4140 steel.Mind the Bending Radius: Protect the integral cable. Standard 2.8 mm cables require a minimum bending radius of 25 mm, while 6 mm armored cables require 35 mm. Never pull or twist the pigtail during mechanical handling

FAQs

  • What is the PR6423/018-140?+
    The EPRO PR6423/018-140 is an 8mm contactless eddy-current sensor paired with the CON021 signal converter.
  • What is the primary measuring range of this system?+
    The system features a standard linear measurement range of 2 mm (80 mils), with an initial air gap setting of 0.5 mm (20 mils).
  • What type of target material should be monitored?+
    The sensor is calibrated for ferromagnetic steel targets. The standard reference target material is 42CrMo4 (AISI/SAE 4140).
  • What are the electrical output characteristics of the CON021?+
    The CON021 converter processes dynamic frequencies from 0 to 20,000 Hz (-3 dB) with a rapid rise time of less than 15 µs. It functions on a supply voltage range of -23V to -32V DC to provide a standard voltage output range of -4V to -20V DC (or alternatively -2V to -18V DC).
