Expert Questions & Answers
Product Design
What does 3.5-inch penetration mean?
The probe sleeves extend 3.5 inches into the housing. This suits machines with thick outer casings between probe mount and shaft.
Why choose this over shorter penetration models?
Select this when your machine wall thickness requires deeper probe reach to properly position the probe tip near the shaft.
Installation & Usage
Are probes included in this housing kit?
No. This housing requires separate purchase of two 3300 XL 8mm proximity probes.
How do I install the NPT fittings?
Thread them into the machine casing 3/4-inch NPT holes. Use thread sealant suitable for your process conditions (temperature, pressure).
Selection Advice
When should I select 3.5-inch penetration?
For applications with thick machine walls, insulation layers, or when additional standoff distance from the shaft is needed for safety or access.
