FAQ

Q: What exactly is a 3300 XL 8 mm proximity probe?

A: It’s a non-contact sensor that uses eddy-current principles to measure the proximity (distance) between the sensor tip and a metallic target (e.g., a rotating shaft).

It converts movement into an electrical signal for vibration and position monitoring in machinery protection systems.

Q: What does the “3300 XL” designation mean?

A: “3300 XL” refers to Bently Nevada’s modern-generation proximity measurement system designed for high accuracy, interchangeability,

and rugged industrial use. The probes are part of a modular transducer system where probes, extension cables,

and Proximitor sensors are electrically consistent and interchangeable.

Q: What kind of output does the probe provide?

A: The probe itself does not provide a standardized process-level signal (like 4–20 mA). Instead, it outputs a

variable signal (via its cable and Proximitor electronics) that’s interpreted by a vibration/monitoring

system to produce displacement or vibration data.
