FAQ

Q1: What exactly does this part measure?
A1: This probe senses the distance (gap) between its tip and a nearby conductive target (e.g., a shaft). The output of the entire transducer system

 is a voltage proportional to that gap, which allows you to monitor static displacement (position) and dynamic displacement

(vibration) of rotating equipment. The high‑temperature (ETR) variant lets you deploy it in

 more demanding thermal environments.

Q2: Is this part an extension cable or a probe?
A2: This part is a probe (specifically, a 3300 XL 8 mm ETR probe). Some listings may label it as “Sensor Probe Cable” but based

 on the official datasheet listing for 330191 it is a probe head with integral cable (9 m). The “90” in the part number

 indicates 9.0 m total length option which includes the cable length. 

Q3: I only need a cable, not a full probe. Could this part be used as a cable?
A3: No — this part is a probe with integral cable (9 m length). If you only need an extension cable to attach to a 

separate probe, you should look at the extension‑cable part numbers in the 3300 XL family (for example

part numbers starting 330130 for standard cable, or 330190 for ETR cable) in the datasheet.

Using a probe head part when you need just a cable

 would be inefficient. listing for
