AI-Powered supplier vetting

SummaryBNSENS Co., Ltd. is identified as a Chinese manufacturer/factory in Jiangsu specializing in sensors and transmitters for pressure, level, temperature, flow, current, switching, and position applications. The supplier describes MEMS and independently developed ASIC expertise, a U.S.-based R&D center, and supply or cooperation relationships involving Emerson, SICK, TSMC, Siemens, Infineon, and Rohm. Its products are reported as serving multiple industrial sectors, and an audit was conducted by BV; however, the audit result and type are provided only as codes, so certification or compliance conclusions cannot be made. Information on after-sales service, financial credibility, quality systems, customization, sustainability, and several R&D services is insufficient. The stated registered capital is omitted from this assessment for privacy.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a high-tech enterprise specializing in sensor development, manufacturing, and trade. Its stated business scope is Electrical & Electronics, and its listed products cover multiple sensor and transmitter categories.

R&D capabilityBNSENS describes a sensor R&D center in Minnesota, core MEMS-chip technology, independently developed ASIC chips, German-origin production-line introduction, and development of additional industrial-control sensors. These statements provide explicit evidence of R&D and technology activity, although the scope and verification of the capabilities are not further documented.

Production capacityThe supplier is classified as a factory and states that it develops and manufactures a broad range of sensor products. Its history includes a sensor production-line introduction and factory relocation, while reported use across oil, gas, power, chemical, metallurgy, food, environmental protection, aerospace, and municipal applications supports production experience; actual capacity, equipment scale, and output data are not provided.

Client casesThe supplier reports that its products are used across numerous industries and cites relationships or sales involving Emerson, SICK, TSMC, Siemens in Vietnam, Infineon, and Rohm. These are explicit customer or business-cooperation claims, but the slices do not provide project details, order scope, duration, or independently verified case evidence.

Product Q&A

Q:What sensing technologies does the FS20X use?

It uses a combination of Infrared (WideBand IR, Near Band IR) and Ultraviolet (UV) sensing technologies, along with a visible sensor for optimal false alarm rejection.

Q:What is the maximum detection range of the detector?

The detection range is in excess of 60 meters (200 feet) for a 0.1m2 heptane reference fire at the very high sensitivity setting.

Q:How does the FS20X handle false alarms?

It features a solar-blind UV sensor, a visible sensor for optimum false alarm rejection, and patented Electronic Frequency Analysis to minimize false alarms from sources like arc welding.

Q:What certifications are available for this detector?

The detector is approved by FM, cFM, ATEX, IECEx (Class I, Divisions 1 & 2), CU-TR, INMETRO, meets SIL 2 requirements, and is certified to EN54-10:2002.

Q:Does the detector support data logging and diagnostics?

Yes, it includes a real-time clock, stores up to 6 pre-fire FirePic events, and logs up to 200 events with date and time stamps. It also supports PC software for fault diagnostics.
