AI-Powered supplier vetting

SummaryNanjing Hangjia Electronic Technology Co., Ltd., established in 2015, specializes in industrial automation and process-control products covering pressure, temperature, level, and flow measurement. The supplier reports ISO9001:2015 and CE certification, documented quality and service procedures, customization and ODM capabilities, recent new-product development, and OEM service for recognized brands. Its production setup includes assembly, laser welding and marking, aging, calibration, and testing lines, with finished-product inspection instructions followed uniformly. Export activity has lasted eight years and represents 51%–70% of total sales. Constraints include no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, showroom, agent, or branch, and no Fortune 500 customer cooperation reported. Financial information identifies records for 2021–2023 but provides no assessable financial results.

Supplier typeThe supplier is identified as a company specializing in the research, development, sales, and service of industrial automation and process-control equipment, including pressure, temperature, level, and flow products. This directly positions it as an industrial measurement and process-control supplier.

CertificationsThe supplier states that it follows the ISO9001 quality management system and holds an ISO9001:2015 management-system certificate; its products also have CE certification. These are explicit certifications relevant to quality management and product compliance.

After-Sales capabilityThe supplier describes customer service from technical consulting through customized production and reports written, implemented procedures for service assessment, corrective and preventive actions, and complaint handling. It offers training overseas but has no overseas agents or branches and reports service coverage in zero countries, indicating documented support capability with limited overseas service infrastructure.

R&D capabilityThe supplier reports R&D capability, new products during the past year, ODM services, and an available SDK. Its stated business scope also includes research and development, supporting a demonstrated ability to develop and adapt industrial automation products.

Production capacityThe supplier lists assembly, laser welding, laser marking, aging, calibration, and testing lines, and states that finished-product inspection instructions are uniformly followed. It also reports in-stock capability, while lacking a valid capacity contract with related subcontractors; the documented in-house facilities nevertheless provide explicit production evidence.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full customization, minor customization, flexible customization, and ODM services. This breadth of stated options indicates strong flexibility for customer-specific requirements.

Client casesThe supplier reports cooperation with customers in construction machinery, water treatment, food and medicine, environmental protection, electric power, metallurgy, and shipbuilding, and states that it provides OEM services for recognized brands. However, it reports no cooperation with Fortune 500 companies, so the evidence supports broad sector experience but not top-tier multinational reference experience.

Product Q&A

Q:What is the operating principle of the HYM610 Turning Fork Switch?

The sensor vibrates at its natural frequency. When the fork touches liquid or powder, energy is consumed by friction, causing the amplitude to decrease sharply and stop. This frequency change triggers the switch to send in-off signals without mechanical motion.

Q:What types of media can this level switch measure?

It is suitable for both liquids and powders. It works effectively even in difficult conditions such as high viscosity, scale formation, agitation, turbulence, bubbles, and high temperatures.

Q:Does the HYM610 require regular maintenance or adjustment?

No, it is maintenance-free and adjustment-free. Since the measuring process is completed by an electronic circuit with no moving parts, no field adjustment is needed regardless of the liquid or powder being measured.

Q:What are the available power supply options and output signals?

The switch supports 24VDC or 220VAC power supply. The output is an SPDT relay (single-pole double-throw), which can be configured for high-low alarm (HLFS) or low-limit alarm (LLFS).

Q:What customization options are available for this product?

Customization includes insertion depth, explosion-proof versions (Exd II CT6), and thread specifications (standard 1'NPT, BSPT optional, or flange installment). Minor and full customization services are also available.
