PR6423/11R-131+CON031 EPRO Reverse Mount Eddy Current Probe Kit

PR6423/11R-131+CON031 is a fully factory pre-calibrated EPRO eddy current transducer assembly, combining PR6423/11R-131 reverse mount proximity probe and CON031 single-channel high dynamic signal conditioner. It belongs to Emerson EPRO PR6423 series non-contact measuring sensors dedicated to turbomachinery TSI protection systems.

Model suffix explanation: /11R represents reverse mounting construction for rear installation on bearing housings where front-side mounting space is limited; /131 stands for 11-meter integrated high-temperature PTFE cable. The probe adopts standard 8mm sensing tip with PEEK insulator and stainless steel housing, IP66 protection rating. CON031 is upgraded signal converter with wider bandwidth up to 20kHz and fast response time <15µs, better suited for high-frequency dynamic vibration measurement compared with CON021. This matched set is factory pre-calibrated, no extra gain adjustment needed after field replacement.

Based on eddy current induction principle, PR6423/11R-131+CON031 performs non-contact measurement of radial shaft vibration, axial displacement, shaft eccentricity and oil film gap on rotating metal shafts. The gap variation signal is converted into standard linear analog output by CON031 preamplifier and transmitted to EPRO MMS3000 and MMS6000 racks for continuous machinery health monitoring and protection interlock.

Key characteristics of PR6423/11R-131+CON031: reverse rear installation for compact bearing housings, 11m long integrated cable for long-distance wiring, 8V/mm standard sensitivity, high linearity, low temperature drift and strong anti-electromagnetic interference. The CON031 converter features high dynamic response for high speed rotating equipment. The whole set maintains stable measurement under high vibration and wide temperature environments, widely adopted in power, petrochemical, oil & gas and chemical plants, complying with API 670 turbomachinery protection standard.

We supply original and surplus PR6423/11R-131+CON031 complete transducer kits. Each matched assembly will be inspected before shipment. Worldwide shipping and short lead time available for plant overhaul, emergency spare replacement and TSI system retrofit.
