Stainless steel stepped probe tubes with tapered tips – the step reduces diameter where the sensor tip needs faster response, and the taper eases insertion into tight wells. Stainless sheaths survive the process side where brass would corrode.
Function and Design
What makes a stepped probe tube hard is repeatability – the hundredth piece has to match the first one. Any drift in the stepped probe tube process is corrected at the machine, not sorted out at inspection.
Design Highlights
- The taper is turned with a controlled angle so insertion is smooth and seating is repeatable.
- Stepped probe tube work is unforgiving: a few hundredths in the wrong place and the assembly will not go together. The stepped probe tube is produced to print, with the features that carry function inspected first.
- Stainless stepped probe tube construction shrugs off washdown, humidity and process media without plating to chip through.
- Material: stainless steel (304 / 316) as the running stock for stepped probe tube work, with certificates available on request.
- Process: deep drawing of the stepped probe tube followed by CNC finishing on critical faces, stepped diameters held across operations.
- Finish: The stepped probe tube ships natural unless the print calls for plating or coating.
- Size: Quoted from your print, so the stepped probe tube size you approve is the size that repeats.
- Custom: Custom stepped probe tube builds to your drawing, with small trial lots possible before committing to volume.
Where It Is Used
Production volumes of this part run in household appliance thermometers, industrial process instrumentation, thermowells for pipes and tanks.
Factory-Direct Advantage
Torque-bearing threads are gauged, not just cut. Any deviation on a sealing face is corrected at the machine, not after plating.
