FAQ

Q: Can this system be used with other PR642x probes?
A: Yes, the converter supports PR6422 through PR6426 sensors. However, optimal performance is achieved with the included PR6423 probe.

Q: Is the unit suitable for outdoor installation?
A: The converter has an IP20 rating and should be installed in a protected enclosure. The probe itself may tolerate harsher environments depending on installation.

Q: What parameters can be monitored with this system?
A: It measures shaft displacement, vibration amplitude, position, and eccentricity in rotating machinery.
