AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with manufacturing, export, service, quality-control, and R&D capabilities. Evidence shows documented procedures for corrective actions, customer complaints, supplier assessment, and R&D design controls. It provides overseas installation, debugging, maintenance, repair, and training, supported by overseas agents or branches, but has no overseas warehouse or showroom. R&D capabilities include recent product development, ODM/OEM services, 3D design, multiple engineering software tools, and documented design verification activities; however, no SDK is available. Production evidence includes four production lines and stated annual capacities of 500,000 level sensors, 500,000 pressure sensors, and 300,000 flow meters, with lead times within 15 working days in both peak and off-peak seasons. No explicit certification, financial-strength evidence, or named customer cases is provided.

Supplier typeThe supplier is explicitly classified as a combined company rather than an offshore company. Its listed offerings cover manufacturing, export trade, service, quality control, R&D, and sustainable development capabilities, indicating a broad integrated supplier profile.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints. It offers overseas debugging, maintenance, repair, training, and equipment installation, and operates through overseas agents or branches; however, it has no overseas warehouse or showroom.

R&D capabilityThe supplier reports new product development during the past year, ODM services, 3D software design, and R&D tools including CAD, SolidWorks, Altium Designer, and LabVIEW. It also maintains design input, output, review, verification, and validation documents, although no SDK is available.

Production capacityThe supplier operates four production lines and reports annual capacities of 500,000 level sensors, 500,000 pressure sensors, and 300,000 flow meters. It lists specialized production and testing equipment, with lead times stated as within 15 working days in both peak and off-peak seasons.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization, together with 3D design and ODM services. These records support broad product customization capability.

Product Q&A

Q:Which kinds of liquids can be measured?

Holykell suggests ensuring medium purity, no dense gas, no suspended solids like crystals, no large sediment deposits at the bottom, and medium viscosity less than 10mPa.s for normal measurement.

Q:What is the maximum viscosity limit for measurement?

Dynamic viscosity greater than 30mPa.s cannot be measured. Normal measurement requires viscosity less than 10mPa.s.

Q:What are the available output signal options?

Output options include Voltage (1-5V/0-5V), Current (4-20mA/0-20mA), and Serial port (RS485/RS232). These are customizable.

Q:What is the measuring range of the sensor?

The level range is 1, 2, 3, 5, 7, 8, 10, 12, 15 meters. UE3001 max is 7 meters, UE3003 min is 5 meters and max is 15 meters.

Q:Is the sensor waterproof?

Yes, the housing adopts NLEPE synthetic material with IP66 waterproof, anti-skid, anti-corrosion, and anti-explosion structure. IP65 is default, IP67 and IP68 are customizable.
