FAQ

Q1: Is this probe compatible with other cables or sensors in the 3300 system?
A: Yes. The 3300 XL 8 mm system is designed with interchangeability of probes, extension cables, and Proximitor sensors—meaning you

can mix and match probes and cables (that meet the specification) without needing to re-bench calibrate each

component. However, when mixing ensure that the cable impedance, connectors, and mechanical

mounting meet the required specification.

Q2: What is the “armour” feature (since model is 330102) and when is it required?
A: The “with armour” version (model 330102) provides added protection (mechanical and potentially EMI) around the

probe and cable assembly (armoured cable). This is useful in harsh industrial environments (mechanical abrasion,

high vibration, risk of damage). If your installation is less severe you might choose the “without armour”

version (330101) which is lighter and less expensive.

Q3: What happens if I choose a longer or shorter cable than 5.0 m?
A: You can choose different total-length options (e.g., 1.0 m, 2.0 m, 9.0 m) by selecting the appropriate code

(“10”, “20”, “90”, etc) in the ordering suffix. The specification supports them. However, any deviation

from the specified combination should still ensure the total system impedance, cable type,

and calibration remain within spec. Excessive cable length may increase

capacitance and degrade signal quality if not designed for it.
