Produced in stainless steel by Aunov Tech, the Temperature Thermocouple Stainless Steel 316 Thermowell 12NPT Sensors is formed and machined on the same floor. Once installed, the sensor housing protects the electronics from vibration, fluid and electromagnetic noise. Die work, machining and CMM inspection are all in-house, so repeat orders stay aligned with the approved sample without a second supplier involved.
Product overview
What defines this stainless steel sensor is, the forming route, the tolerance band and the sealing faces, all held to the drawing and verified at first article.
Forming, machining and finishing for this stainless steel sensor happen on one site, which keeps the sample loop inside our own schedule, and the same die can be re-cut from the original data.
How it is manufactured
This is how the stainless steel sensor is built: Blanks are drawn in stages, with interstage annealing where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Batch records for the open sleeve are filed against the part number, so process settings are reused instead of re-invented. Deviations on the open sleeve are reported before shipment rather than found on your assembly line.
Materials and surface finish
Base materials in stock: cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel sensor runs in 304 / 316 stainless steel.
The finish is chosen for a clean working surface: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this stainless steel sensor travels with the part number on every reorder.
Repeat open sleeve orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved open sleeve sample governs later runs, and any grade change is agreed in writing first.
Quality control and inspection
Production runs under an ISO 9001 certified quality system: stock arrivals are checked against mill certificates, first-article geometry is confirmed on the CMM, and production batches are inspected on a sampling plan. Every open sleeve batch carries thread gauging and seal face inspection. Torque, leak and pressure tests are available where the assembly needs them, with certificates included in the shipment file.
Typical applications
This stainless steel sensor is used in sensor and thermostat assemblies for customers who own the drawing and the tooling.
One drawing for this stainless steel sensor is commonly applied to several programmes, so the specification is set by the toughest of them, and no re-tooling is needed.
Options and variations
Frequently varied options
Typical customer decisions: material and coating for the duty, thread classes, hex or flange mounting, sealed cable exits, vent holes and finishes matched to the measured medium, and whether orders run as prototypes, pilot lots or scheduled batches.
Quotes show which options the current die already supports, keeping the trade-offs visible from the start.
Specifications
| Item | Temperature Thermocouple Stainless Steel 316 Thermowell 12NPT Sensors |
|---|---|
| Brand | AUNOV |
| Designing | Design intent is read from the print, and any conflict in the drawing is raised before quoting. |
| Tooling | Tooling is built and held under your part number, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Pre-production samples come with a full inspection report, so the sample is retained as the master, and the signed sample is kept for future reorders. |
| Materials | Stock covers carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Natural, plated or coated – the print decides, and the agreed finish is logged; alternatives quoted with the quotation, samples approved in writing. |
| Processing | Deep drawing followed by CNC finishing on critical faces; first articles verify the whole flow before the run is released. |
| Equipment | Press line for drawing, CNC cells for finishing, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; dimensional reports accompany the first article. |
| Delivery terms | Shipping terms are set with the order: FOB, CIF or DDP, T/T or L/C, door delivery quoted. |
Packing and shipment
The finish on this stainless steel sensor dictates how it is packed: interleaves, bags or trays are matched to the surface treatment, in sealed cartons on export pallets, documented and marked to your instruction.
