For a point-type industrial flame detector, the published FOB price from Chinese export channels is US$320.00-350.00 per set at a one-set minimum order, with the housing in anodized aviation aluminum plus stainless steel and CCC certification [S2]. That figure is the cleanest reference datapoint on the open market for an IR+UV point detector in 2026, and it sets the floor for the rest of this cost map.
The same supplier table puts a Fire Sirenta-Fiv sounder at US$7.30/piece, an alarm panel expansion module at US$27.00/piece, and UL/CE magnetic reed switches at US$0.80-1.50/piece, with minimum orders of 100 pieces for those accessories [S2]. Those accessory prices are useful because a working flame-detection loop is never just the detector head: it includes the detector, the sounder or strobe, the panel interface, and cabling, and the detector is by far the most expensive single line item.
What a flame detector actually costs at the line item
The point-type IR and UV flame detector test instrument quoted at US$320.00-350.00/set covers the detector body plus an integrated IR transmitting tube and UV phototube test source, with a stated IR waveband scope of 0.5 µm to 5.5 µm and a UV waveband scope of 185 nm to 255 nm [S2]. That dual-band coverage is what you would expect for a hydrocarbon-flame detector designed to discriminate real fires from arc welding, sunlight, and hot surfaces; it is not the cheapest sensor architecture on the market, and the price reflects it.
For an engineer pricing a loop, the more useful way to read the line item is detector-head cost plus proof-test accessory cost. A handheld IR/UV test lamp is the standard method of doing a non-open-flame functional check on an installed detector, and the ABS-H04-style unit integrated into the supplier listing is the canonical example of that accessory class [S2]. A serious maintenance budget will price the test lamp at roughly the same order of magnitude as a low-end detector head, so do not spec the detector and forget the tester.
Sensor type as the primary price axis
Sensor technology is the single biggest cost driver on a flame detector, and the published IR+UV point-type unit at US$320.00-350.00/set is mid-range, not entry-level [S2]. Single-band UV tubes are the cheapest because the tube itself is mature commodity hardware, but they false-alarm on arc welding and gamma radiation; single-band IR (typically 4.3-4.8 µm CO2 resonance) is the workhorse for hydrocarbon fires but can be blinded by hot CO2 exhaust; IR3 (three-band IR with neural-network discrimination) sits at the top of the price band because it dramatically reduces false alarms in turbine enclosures and offshore modules.
Dual IR/UV (the architecture in the S2 listing) is a balanced choice for general industrial use, where the buyer wants coverage of both invisible hydrocarbon fires (IR) and hydrogen, silane, or ammonia flames (UV) without paying the IR3 premium. A working selection logic and a side-by-side of the same loop under different sensor choices is laid out in a Flame Detector Selection Guide, which is a useful cross-reference when the sensor decision is the dominant cost variable.
Hazardous-area certification as the second price axis
Certification tier is the second cost axis and it is non-linear: a CCC-certified detector is the price floor in the Chinese export market, a CE/ATEX or IECEx-rated unit sits one tier above, and a SIL2/SIL3 functional-safety certified unit sits well above that [S2]. The published listing carries CCC only, with a GB specification code, and that is consistent with the US$320.00-350.00/set FOB figure being the entry point rather than a hazardous-area premium price.
For a European or Middle Eastern end user, the same detector housing with ATEX 2014/34/EU Zone 1 or IECEx Zone 1 marking will typically price at a meaningful premium over the CCC baseline, driven by the additional component certification, the Ex d flameproof enclosure testing, and the documentation pack. Buyers should treat certification as a separate cost line, not as a hidden surcharge, because it changes the supplier list as much as it changes the unit price.
Minimum order, lead time, and total landed cost
Minimum order quantity has a real effect on effective unit price. The S2 flame detector listing accepts a 1-set minimum order at US$320.00-350.00/set, while the alarm accessories on the same page require 100-piece minimums at unit prices between US$0.65 and US$27.00 [S2]. For a single-loop demonstration build, a 1-set minimum is convenient; for a multi-unit plant retrofit, the per-set price often falls because the OEM moves to a tiered quotation once the volume crosses the OEM's internal threshold.
Total landed cost has to include the test instrument, the detector head, the panel interface module, and the sounder/strobe, plus cabling, conduit, and commissioning labor. Using the S2 figures as the floor, a single detection point with sounder and panel interface lands in the high-hundreds to low-thousands of US dollars before labor, and that is before any Ex-rated gland, junction box, or cable premium is added. The wider cost-driver landscape for industrial instrumentation procurement is mapped in Industrial Hose Pricing 2026, and the same volume-tier / certification-tier logic applies.
Who this price band fits, and who it does not
The US$320.00-350.00/set band fits integrators building general industrial fire and gas panels, skid-packagers specifying detection for small compressor skids or generator enclosures, and EPC subcontractors buying detector heads for non-hazardous or Zone 2 areas where a CCC-only certification is acceptable [S2]. It also fits academic and training builds, where the detector is used as a teaching reference for the working principle of optical flame detection rather than as a life-safety device.
It does not fit offshore FPSO turbine enclosures, where IR3 with EN 54-10 or FM 3260 approval is the de facto spec, nor does it fit pharmaceutical or semiconductor cleanrooms, where the detector housing material, IP rating, and cleanroom compatibility drive cost more than the sensor itself. For those buyers, the relevant benchmark is a SIL2-rated IR3 detector with a published price several multiples above the S2 baseline, and a longer approval lead time measured in months rather than weeks. A related detector family is the gas detector, which is typically specified alongside the flame detector on the same loop and has its own certification and price logic.
Functional safety and the real cost of ownership
Proof-test interval is the hidden lifetime cost driver on a flame detector. Optical windows accumulate oil mist, salt, paint, and ice, and a detector that is not proof-tested on the OEM schedule will fail the next real fire event; the OEM-recommended interval on most industrial units is 6 to 12 months, with shorter intervals in dirty service. The IR+UV test instrument in the S2 listing is a non-open-flame test source, which is the practical answer to the proof-test problem on a live plant: it lets the technician stimulate the detector without a real fire. [S2]
For a SIL-rated loop, the proof-test interval is not a maintenance choice, it is a safety-instrumented-function parameter that feeds directly into the probability of failure on demand calculation, and cutting it raises the lifecycle cost in test labor. Total cost of ownership over a 10-year detector life is therefore roughly three times the purchase price: one part hardware, two parts proof testing, window cleaning, calibration gas where applicable, and replacement of consumable UV tubes. Buyers who price on purchase price alone consistently underestimate the loop's true cost, and a structured comparison against a dust detector loop on the same panel is often the easiest way to expose that gap.
Sourcing signals worth tracking
Two signals to watch in the next two quarters: first, any movement on the S2-style FOB price band as a leading indicator of the broader Chinese export market for point-type flame detectors, because the US$320.00-350.00/set figure is the cleanest public reference for the entry tier [S2]; second, any new ATEX or IECEx variant listings from the same supplier base, which would compress the certification premium that currently separates CCC units from Zone 1-rated units. A related trackable is the supplier's own expansion into flame detection test instruments adjacent to its existing alarm-panel and magnetic-reed-switch product lines [S2].
