FAQ
Q: What materials are compatible with PR6423/012-130 probes?
A: Standard ferromagnetic steels such as 42CrMo4 / AISI 4140 are recommended.

Q: Can the CON021 handle high-frequency vibration signals?
A: Yes, it supports up to 20 kHz with fast <15 μs rise time for transient events.

Q: Is this system suitable for sleeve-bearing machines?
A: Absolutely. Its design allows measurements where case-mounted sensors cannot be applied.

Q: Are environmental conditions a concern?
A: The sensor is IP66 rated and can operate from –40 °C to +150 °C. The converter operates from –30 °C to +100 °C with IP20 protection.
