FAQ

Q: What is the difference between PR9266 and PR9268?
A: PR9266 is high-temperature version for up to 200℃ environment; PR9268 is standard velocity sensor with lower temperature rating and different sensitivity.

Q: Does PR9266/11-000 need external power supply?
A: No, it is self-generating electrodynamic sensor, powered by mechanical vibration movement, no 24VDC excitation needed.

Q: Can it connect to Bently 3500 monitor?
A: Yes, it can be matched with 3500 velocity monitor module, but signal range and sensitivity need to be configured correctly.
