OEM China Custom Stainless Steel Waterproof Sensor Probe Housing Thermowell - OEM Support from Reliable Suppliers and Factory Service, Quotes
Product Description
Product Overview
Shenzhen Sunmy Hardware Co., Ltd. presents our high-performance Stainless Steel Sensor Probe Housing, specifically engineered for temperature sensing, soil moisture detection, and fluid monitoring systems.
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.
⚙️
Precision CNC Turning
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.
✨
Surface Treatment
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).
🔒
Sealing Interface
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).

Technical FAQ
▶
Q1: What is the Minimum Order Quantity (MOQ) for a custom probe size?
A1: At Sunmy, we support our clients' development phases. For custom dimensions, we can start with a low MOQ for prototyping (e.g., 50–100 units) before moving to mass production.
▶
Q2: Can you ensure the housing is waterproof?
A2: The metal housing itself is seamless at the tip due to the turning process, making it 100% leak-proof. The final waterproof rating depends on how you seal the open end (epoxy potting or end-cap). We can design the flange specifically to hold your preferred sealing method securely.
▶
Q3: Do you provide material certification?
A3: Yes. We are a transparent manufacturer. We provide material certificates (RoHS, REACH, Mill Certs) for our Stainless Steel 304/316 materials upon request to ensure compliance with your local regulations.
▶
Q4: I need a specific shape for the tip (e.g., needle-sharp vs. rounded). Can you do it?
A4: Absolutely. Since we use CNC Lathes, we can program any tip geometry you require—whether it's a sharp needle for piercing or a rounded bullet tip for safety.

Frequently Asked Questions (FAQ)
Q1
What stainless steel grades are available, and how do I choose the right one?
We offer SS304, SS316, and SS316L. SS304 is suitable for general-purpose and non-corrosive environments. SS316 provides superior resistance to chlorides and saltwater. SS316L (low carbon) is recommended for medical, food-grade, or high-temperature welding applications where maximum corrosion resistance is critical.
Q2
Can the probe housing be used in high-pressure water pipe installations?
Yes. Our housings are CNC-turned from solid or thick-walled tube stock, providing excellent structural integrity. We can machine NPT, BSP, or metric threads at the mounting end for a secure, pressure-rated connection. Wall thickness can be adjusted to meet your specific pressure rating requirements.
Q3
Is the probe housing compatible with DS18B20, PT100, and other standard sensors?
Absolutely. The inner diameter and length of each housing are fully customizable to accommodate your specific sensor module. Simply provide the sensor dimensions (e.g., DS18B20 TO-92 package or PT100 element size), and we will machine the housing to ensure a precise, snug fit.
Q4
What is the typical lead time from design confirmation to delivery?
For prototype orders, the typical lead time is 7–15 business days after design confirmation and sample approval. Mass production lead times vary by quantity but generally range from 15–30 business days. We will provide a detailed production schedule upon order confirmation.
Q5
Can Sunmy handle surface finishing or secondary operations like laser engraving?
Yes. As a full-service precision parts manufacturer, we offer a range of secondary operations including mirror polishing, brushed finishing, passivation treatment, and custom laser engraving for part numbers or brand logos. All finishing processes are performed in-house for consistent quality control.
Q6
How do I submit my custom design for a quote?
You can submit your project using the inquiry form above. Please include your technical drawing (PDF, DXF, STEP, or similar), key dimensions (OD, ID, length, tip geometry), required material grade, desired quantity, and any special requirements. Our engineering team will respond with a detailed technical quote and free DFM (Design for Manufacturability) review within 24 hours.
