What is the environmental rating of the enclosure?

The enclosure has an IP66 rating, making it dust-tight and protected against powerful water jets, suitable for harsh industrial conditions.

How does the self-checking feature work?

The device performs internal electronic self-checks once per second to verify proper operation. If an error is detected, the flame relay and self-check relays open, and the device displays 'lockout', which can only be cleared via manual reset at the touchwheel interface.

What is the weight and physical size of the unit?

The unit weighs 2.8 kg (6.1 lbs). Its physical dimensions are a diameter of 11.7 cm (4.6 inches) and a length of 15.5 cm (6.1 inches).

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 safety integrity level is this device certified for?

The Honeywell U2-101xS series is certified for use in SIL 3 environments, with a Safe Failure Fraction (SFF) of >99% and a Probability of Failure on Demand (PFD) ranging from 1.15x10-4 to 1.20x10-4 depending on the specific model.

Q:What types of sensors are included in the viewing head?

The device can include one, two, or all three sensors: UV, Tron, IR, and UVSS. The specific combination depends on the model ordered, such as U2-1010S or U2-1018S.

Q:How is the device connected to the burner control system?

It offers two connection methods: quick disconnect (non-PF Models DIV2, ZN2) or pigtail external connection (PF Models DIV1, ZN1). The pigtail models are available in 50-ft (15m) or 100-ft (30m) lengths.

Q:What are the input power requirements?

The device requires 22-26 VDC with a maximum current draw of 120 mA (approximately 3.5 watts).

Q:Does the device support remote communication?

Yes, it supports remote communication via a 2-wire RS485 interface compatible with the Modbus RTU protocol.
