Why Engineers Specify This Model
- Direct API 670 Compliance – Designed from the ground up to meet the machinery protection standard mandated by EPC contractors and end-users in oil & gas.
- System-Matched Accuracy – The PR6424/002-130 + CON021 combination is factory-calibrated as a matched set with EMERSON Epro drivers (PR6423 series), eliminating field calibration uncertainty.
- Non-Contact Measurement – Zero mechanical wear; sensor life is independent of shaft rotation speed or vibration amplitude.
- Robust Construction – IP67-rated probe body withstands oil mist, coolant splash, and high-humidity environments common in turbomachinery enclosures.
- Wide Temperature Range – Qualified from -40 °C to +120 °C, suitable for both arctic outdoor installations and hot-section turbine pedestals.
- Plug-and-Play with MMS 6000 / 3000 – Recognized natively by EMERSON Epro protection racks; no signal conditioning adapters required.
- Long Field Track Record – The PR6424 series has accumulated decades of installed-base hours in refineries, power plants, and offshore platforms worldwide.

Application-Specific FAQ
Q: Is the PR6424/002-130 CON021 compatible with non-EMERSON protection systems?
A: The probe outputs a standard voltage signal proportional to gap distance. It can interface with third-party monitors (Bently Nevada, Metrix, etc.) provided the driver/proximitor is matched and the input impedance is compatible. Consult your system integrator.
Q: What is the difference between PR6424/002-130 and PR6424/002-030?
A: The three-digit suffix after the hyphen denotes cable length in decimeters. /002-130 = 2 m probe + 130 cm (1.3 m) integral cable segment. Always verify total system cable length (probe + extension) matches your driver calibration.
Q: Can this sensor be used for axial position (thrust) measurement?
A: Yes. With the appropriate MMS 6120 axial position module and correct mounting orientation, the PR6424 series is widely used for thrust bearing axial position monitoring per API 670.
Q: What target material is required for accurate measurement?
A: The sensor is calibrated for AISI 4140 steel. Other ferromagnetic or conductive materials will shift the sensitivity curve. EMERSON provides correction factors for common alternative target materials.
Q: Do you provide installation and commissioning support?
A: Konmask.com provides remote technical support for installation queries. On-site commissioning services can be arranged through our partner network — contact us for details.
Q: What is the lead time for this part?
A: Standard lead time is 3–7 business days for in-stock units. Expedited options available. Contact us for real-time stock status.
