The Stainless steel NTC sensor probehousing (5) is produced by Aunov Tech from stainless steel, formed and finished under one roof. In service, the sensor housing shields the sensing element and positions it in the measured medium. Die work, machining and CMM inspection are all in-house, so first-article dimensions hold through volume batches on one production route.
Product overview
The critical features of this stainless steel sensor are, draw depth, wall band and the surfaces that forming cannot hold, controlled from the approved first article onward.
Tooling and finishing for this stainless steel sensor run under one roof, so the route from print to sample stays short, with process data archived for repeat orders.
How it is manufactured
The route for this stainless steel sensor is fixed and repeatable: Drawing runs from flat blank to finished envelope in one controlled sequence; the part is annealed between stages so the wall thins evenly.
Production batches of the plain open-top sensor are gauged back to the signed first article, not to a memory of it. That record is what every plain open-top sensor reorder is built on, so nothing changes silently between shipments.
Materials and finishing
Our stock list runs to SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel sensor is costed in 304 / 316 stainless steel.
With the working face exposed, the finish is selected for cleanliness: electrophoresis, powder coating, anodising and zinc / nickel plating. It is fixed on the drawing for this stainless steel sensor, so repeat orders never reopen the question.

Quality control
Quality management is certified to ISO 9001: incoming material is verified against mill certificates, first-article geometry is confirmed on the CMM, and routine sampling keeps batches aligned with the first article. Thread class and sealing faces of the plain open-top sensor are verified on every run. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the batch file carries the results.
Applications
Typical installation of the stainless steel sensor is in thermal sensing and appliance control assemblies for customers who own the drawing and the tooling.
The same stainless steel sensor is used across several platforms, so the specification is set by the toughest of them, without a second tooling round.
Customization and options
Where designs usually differ
The options most often changed on this stainless steel sensor: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and whether orders run as prototypes, pilot lots or scheduled batches.
The quotation for this stainless steel sensor marks what the existing tooling can do, so you can see which options are free and which need new tooling. Each plain open-top sensor reorder is priced with the original split.
Specifications
| Item | Stainless steel NTC sensor probehousing (5) |
|---|---|
| Brand | AUNOV |
| Designing | Design intent is read from the print, and any conflict in the drawing is raised before quoting. |
| Tooling | Progressive and drawing dies are designed and built in house, so die cost stays transparent, and the die remains dedicated to your part. |
| Samples | Pre-production samples come with a full inspection report, so any deviation is corrected at sample stage, and mass production is gated on that approval. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; mill certificates and heat numbers accompany the first article. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the agreed finish travels with the part number. |
| Processing | Drawn shell with machined seats and threads where the print calls for them; batch records are filed so a repeat order starts from approved data. |
| Equipment | Deep drawing presses plus CNC turning centres for machined faces, with in-house toolmaking to keep dies and fixtures maintained. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, T/T with deposit and L/C for larger runs; price breaks tie to annual volume. |
Packaging and delivery
The packing method protects the surfaces of this stainless steel sensor: interleaving, bagging or tray packing is matched to the surface, then cartons are sealed and palletised, with marks and documents as you specify.
