BWLK-FQXThe flame detection and alarm system, known as the fire shutdown alarm interlock device, is specifically designed and developed to meet the needs of industries such as petrochemical, metallurgical, coal chemical, and ceramic sectors.EquipmentThe product is equipped with a flame detector.Explosion-proof pressure switchFlammable Gas Detector, featuring flame extinction, gas under-pressure, and gas leakage detectionAlarmInterlock protection features, with simple operation, reliability, and easy maintenance, suitable for flame detection and shutdown, under-voltage, and leakage interlock alarms in various gas burners and oven loaders.

I. Function Overview: 

 This control box is explosion-proof, explosion-proof grade:ExdbebⅡBT4The control box is equipped withBWZJ-43-KUltraviolet flame switches, circuit breakersSwitched-mode power supplyControl modules, buttons, indicator lights, and other control components. Inside the box.BWZJ-43-KUltraviolet flame switches utilize our high-performance products, with electrical components sourced from renowned domestic brands to ensure reliable equipment operation. The system is manually operable./Automatic mode conversion with shutdown, gas under-pressure, and gas leakage interlock protection; in case of unexpected shutdown, gas under-pressure, or gas leakage during system operation.(The leak alarm interlock can be enabled or disabled according to process requirements via interlock jumper wires. That is, when the jumper wire is plugged into the socket, the system will only alarm for gas leaks without interlocking to close the gas valve; when the jumper wire is unplugged from the socket, the system will both alarm for gas leaks and interlock to close the gas valve simultaneously. At the time of product shipment, the jumper wire is plugged into the socket by default, and it is set to only alarm for gas leaks without interlocking to close the gas valve.At that time, it can be handled promptly.AlarmShut off the gas solenoid valve to ensure system safety, and may alsoManual/Automated Running SignalsFire SignalGas valve open signal, fireout fault signalUnder-voltageFaultSignal, LeaksFaultSignalFault alarm signalIn switch quantity form or485Interface (optional) uploaded to the host computer for ease of operationReal-timeSurveillance.
