Early fire detection is essential for high-risk industrial processes involving flammable gasses, vapors, and combustible dust. Zhongcheng Machinery's Explosion-proof Integrated Flame Detector provides intelligent, real-time flame monitoring designed especially for dangerous areas. This gadget monitors at about 60mA and increases to about 100mA during alarm states while running on DC24V ±10% at just 3W. It can detect flames up to 25 meters away for typical 0.5m³ fires because to its impressive field of view, which spans 100° (infrared) and 120° (ultraviolet). Our detector, which is certified to Ex, IECEx, ATEX, ISO, HSE, TÜV, and BV standards, combines great false-alarm suppression with high sensitivity to keep your operations safe and productive.
Our integrated flame detector differs from traditional fire detectors by integrating optical sensors, signal processing modules and protective housing into one standalone unit ready for field installation. This structure avoids common drawbacks found in split multi-component systems.
Dual-band infrared and ultraviolet detection technologies is used by the apparatus. This multi-spectrum method separates real flame fingerprints from interference sources such as lightning, arc welding, and sunlight. Without the operational delays brought on by false alarms, you receive accurate alerts.
The detector's high-performance 32-bit CPU allows it to process flame data at incredibly fast speeds. Response times are measured in milliseconds, allowing your team valuable time to start emergency procedures before a little event turns into a disaster.
You can fully customize operating parameters to fit your unique situation. You can customize sensitivity levels and alert logic to your operational reality, whether you are in charge of chemical processing facilities or offshore drilling rigs.

Your operations don't stop because of dust, smoke, or low visibility. Our detector maintains reliable flame recognition even in optically degraded environments where conventional sensors fail.
The non-contact detection principle means no physical interaction with the flame source is required. This extends equipment lifespan and reduces maintenance cycles significantly.
Industrial sites generate countless IR and UV sources that confuse traditional detectors. Welding operations, heated machinery, and direct sunlight have historically triggered expensive false alarms.
Our dual-band technology analyzes flame-specific flicker frequencies and spectral signatures. The built-in processor filters out non-fire radiation patterns, delivering alarm reliability that keeps your team focused on real threats.
In environments handling flammable materials, detection speed directly correlates with damage control. Our Explosion-proof Integrated Flame Detector identifies ignition events within milliseconds of flame appearance.
This rapid response integrates seamlessly with your fire suppression systems, enabling automatic activation of deluge systems, shutdown sequences, and evacuation protocols before flames can propagate.
Every facility faces unique fire risks. Offshore platforms deal with hydrocarbon fires amid salt spray and vibration. Chemical plants must detect invisible hydrogen flames while ignoring heat radiation from reactors.
You can adjust detection algorithms, sensitivity levels, and alarm thresholds directly through the RS485 interface. This flexibility ensures optimal performance regardless of your specific hazard profile.
Hydrocarbon processing poses constant fire and explosive dangers from upstream drilling to downstream refining. Our detector keeps a close eye on loading facilities, storage tanks, separator vessels, and wellheads around-the-clock.
Even in the event of catastrophic gas leaks, the device's explosion-proof construction guarantees that it never becomes an ignition source. Just when you need them most, your safety systems continue to function.
Furnaces, distillation columns, and chemical reactors all handle reactive materials at extremely high temperatures. In these conditions, conventional heat detectors react too slowly.
Before runaway reactions can occur, our flame detector instantaneously detects the optical signature of combustion and initiates emergency cooling, inert gas injection, or material isolation.
New difficulties in detecting fires have been brought about by the energy shift. In daylight, hydrogen flames burn almost imperceptibly, defeating both visual monitoring and traditional UV-only detectors.
Our dual-spectrum method provides accurate detection for this crucial new application by capturing both the UV emissions and particular infrared patterns of hydrogen combustion.
Before being shipped, each unit is put through a thorough quality inspection. To ensure adherence to ATEX and IECEx flamepath criteria, explosion-proof path diameters are assessed.
Spectral sensitivity is calibrated using sources of verified blackbody radiation. This guarantees that your detector will react correctly throughout the whole wavelength range that it can operate.
Devices undergo temperature cycling from -40°C to +85°C as well as vibration testing that mimics years of demanding industrial operation as part of environmental stress screening. Only units that continue to operate fully move on to the final examination.
Through immersion tests, water-tightness testing verifies IP66/IP67 grades. Internal electronics are shielded from moisture intrusion, which could damage circuits or obscure optical components.
Testing for false alarm immunity exposes detectors to radiant heaters, arc welding equipment, and modulated sunlight. To satisfy our release requirements, units must maintain stability during certain non-fire trials.
Q: How does dual-band detection improve reliability compared to single-spectrum sensors?
A: Single-spectrum detectors struggle to differentiate fire from interference. Our UV sensor captures the distinctive ultraviolet emissions of combustion, while the IR channel analyzes flicker patterns. The processor correlates both data streams, confirming genuine flames while rejecting solar radiation and hot surfaces.
Q: What kind of upkeep is necessary for the detector?
A: Examine the optical window every month in high-dust conditions and use lens cleaning products that have been approved by the manufacturer. When dust buildup impairs detection capabilities, the device's automatic optical self-checking system sounds an alert. Only quarterly inspections are necessary for the majority of systems.
Q: Can I integrate this with my existing fire alarm panel?
A: Yes. The detector provides standard 4-20mA analog output and relay contacts compatible with virtually all industrial fire and gas systems. The RS485 interface offers digital integration with modern SCADA platforms using Modbus protocol.
Q: How can I be sure the detector is operating properly?
A: Make use of an explosion-proof test lamp that produces spectrum output and calibrated flicker frequencies that correspond to actual flames. Without actually starting a fire in dangerous regions, these test devices provide safe functional verification.
Q: What is the expected operational lifespan?
A: With proper maintenance, expect 10-15 years of reliable service. The solid-state optical sensors contain no consumable elements. The primary wear item is the optical window, which can be cleaned or replaced as needed without returning the entire unit.
Q: Does heavy smoke affect detection performance?
A: IR technology penetrates light to moderate smoke better than UV wavelengths. However, very dense smoke will attenuate the signal. Position detectors to maintain clear line-of-sight to potential fire sources when possible. Multiple detector placements provide overlapping coverage in high-risk zones.
