ODM Custom Stainless Steel Waterproof Sensor Probe Housing / Thermowell from China Suppliers and Factory - OEM Support Available Service, Quotes
Product Description
Product Overview
Designed with a robust, pointed tip structure, these housings are ideal for applications requiring direct insertion into soil, viscous liquids, or pressurized water pipes. As a specialized manufacturer of Precision Turned Parts, Sunmy offers full OEM/ODM support, allowing us to customize the length, diameter, wall thickness, and flange design to perfectly match your sensor modules (DS18B20, PT100, etc.).
We provide a durable shield for your sensitive electronics against moisture, corrosion, and physical impact.
Manufacturing Process & Insights
Our probe housings are manufactured using advanced CNC Precision Turning (Computer Numerical Control) technology. Unlike standard stamping or tube drawing, our turning process ensures superior structural integrity and dimensional accuracy.
The pointed tip is machined directly from the solid bar or thick-walled tube stock, ensuring a seamless, leak-proof transition that is stronger than welded tips.
We apply a high-grade polishing process to reduce surface roughness. This minimizes soil adhesion or fluid drag and ensures the probe is easy to clean and sterilize (vital for food/beverage or medical applications).
The open end features a precision-machined flange or rolled rim, designed to accommodate O-rings or epoxy potting, ensuring a high waterproof rating (customizable to IP68 standards).
