Frequently Asked Questions

What is the difference between 330102 and 330103?

330102 models have 3/8-24 UNF thread with armor option. 330103 models have M10 x 1 metric thread without armor.

When to choose armored cable?

Select armored version when cables may experience abrasion, crushing, or heavy mechanical stress during operation.

What thread size is this?

3/8-24 UNF (Unified Fine) thread. Common in North American and inch-system installations.

Compatible with 3300 XL systems?

Yes. This 330102-60-90-10-02-CN works with all Bently Nevada 3300 XL proximitors and monitors.

What gap setting for vibration?

Set initial gap to -9 Vdc (approximately 1.27mm or 50 mils). This centers probe within linear range.
