AI-Powered supplier vetting

SummaryBluefin Sensor Technologies Limited is a China-based limited company in Guangdong, established in 2019, with 9 employees. It reports broad customization and ODM capabilities, recent new-product development, and OEM service for well-known brands. Manufacturing is supported by valid contracts with associated subcontractors, documented finished-product inspection instructions, two quality inspectors, and listed production and testing equipment. However, the records explicitly state no quality assurance, no own-brand quality-control capability, no inventory capacity, and no overseas warehouse, showroom, agent, branch, or offline trade-show participation. After-sales support is identified as repair, but the effectiveness of complaint handling is not clearly evidenced. Financial records identify years for financial capacity, cash flow, and profit indicators, but provide no substantive performance values, so credibility cannot be determined. No certification information or customer names/cases are provided.

Supplier typeThe supplier is identified as Bluefin Sensor Technologies Limited, a limited company established in China’s Guangdong province in 2019, with a combined company type and 9 employees. The provided address is in Dongguan, Guangdong, China.

After-Sales capabilityThe supplier lists repair among its overseas service offerings and identifies Shenzhen Yantian Port as the nearest-port service location. However, it has no overseas warehouse, showroom, agent, or branch, serves zero listed overseas-service countries, and the evidence does not clearly demonstrate effective complaint handling.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and supports customization from samples, designs, full customization, minor customization, and flexible customization. It does not have an available SDK, but the evidence still explicitly supports product-development and design capability.

Production capacityThe supplier reports OEM service for well-known brands, valid manufacturing contracts with associated subcontractors, two quality inspectors, documented finished-product inspection instructions, and equipment including tube-cutting, automatic screw-driving, sealing-test, laser, and resistance-test machines. It has no in-stock service capacity, while peak-season lead time is one month and off-season lead time is within 15 working days.

Customization capabilityBoth R&D and design-service records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. This indicates broad stated customization coverage across the supplier’s design and service capabilities.

Product Q&A

Q:What materials are available for this level switch?

The sensor is crafted from high-grade stainless steel, PVC, polypropylene (PP), PVDF, and NBR, allowing adaptation to diverse liquids and environmental requirements.

Q:Can the float size and length be customized?

Yes, the sensor allows customization in float sizes, lengths, and switch configurations to meet unique application demands. Lengths range from 30-400mm for PP and 45-1000mm for stainless steel.

Q:What types of fluids can this switch monitor?

It is suitable for edible water, oil, diesel, high-temperature liquids, corrosive liquids, and various industrial media, depending on the chosen material.

Q:How is the sensor installed in the tank?

It features a threaded design that screws directly into the tank, creating a strong, leak-proof connection. It can be top-mounted, side-mounted, or bottom-mounted.

Q:What is the operating principle of the switch?

The float rises and falls with the fluid, engaging a high-sensitivity reed switch to indicate specific levels. It can transition between normally open and normally closed states.
