It’s a rugged, non-contact eddy current sensor built for the heavy hitters—steam turbines, gas compressors, hydro machines, and huge fans. Basically, if it spins fast and is critical to your operation, this is the probe you want watching it.
Why Case Sensors Don't Cut It
Here’s the real talk: if you’re running sleeve bearing machines, slapping a vibration sensor on the outside casing is a waste of time.
| The Problem: That thin film of oil in the bearing? It acts like a shock absorber. It kills the vibration signal before it ever reaches the case. | The Fix: You need to measure the shaft directly. The PR 6423 mounts right through (or inside) the bearing to see exactly what that rotor is doing, unfiltered. |
Since it doesn’t touch the surface, it’s perfect for measuring both static and dynamic changes. It keeps an eye on:
The Wiggle: Shaft vibration and eccentricity.
The Push: Thrust (axial displacement).
The Gaps: Differential expansion and valve positions.
The Specs (The Boring but Important Stuff)
By the Book: It’s fully compliant with API 670, DIN 45670, and ISO 10817-1.
Safety First: It’s rated for explosive areas (Eex ib IIC T6/T4)
The Family: If the 6423 isn't the perfect fit, it has siblings (PR 6422, 6424, 6425). Just make sure you pair it with the right converter (like the CON 011/91 series) to complete the system.
Real Talk:
You can't just plug the probe directly into your control system. It won't work. The signal coming off that PR 6423 is raw—it needs to be cleaned up and converted before your monitors can make sense of it.
The Gear:
That’s where the CON 011/91 (or the 021/041) comes in. Think of it as the translator. It takes the mess from the sensor and turns it into a clean voltage signal that actually tells you the gap distance.
Don’t Mess It Up:
This is a matched set. You can’t just grab any random converter from the bin.
Got a PR 6423? You need the specific CON unit calibrated for it.
Don't forget the extension cable.
The Gist:Probe + Cable + CON Converter = The only way this works.
