This product passes the Ex d IIB T4 Gb explosion-proof certification, suitable for Zone 1 and Zone 2 dangerous environments. The main structure is made of 304 stainless steel and galvanized steel, which is anti-corrosion and impact-resistant. It is equipped with a LoRa wireless communication module, which can realize long-distance data transmission in dangerous areas without laying wired cables, reducing the cost of explosion-proof wiring. It adopts automatic weight calibration technology, which can complete calibration without shutting down, improving operation efficiency. The accuracy reaches ±0.2% full scale, meeting the accurate metering requirements under dangerous working conditions and avoiding production losses caused by metering errors.

Detailed technical parameters include: conveyor belt width of 650 Millimeters, rated load of 30 Tons per hour, explosion-proof grade of Ex d IIB T4 Gb, operating voltage of 220V 50Hz or intrinsically safe 24V battery, protection grade of IP67, working temperature range of -20℃ to +60℃, sensor range of 0-800 Kilograms, communication mode of LoRaWAN/RS485, body dimensions of 2000mm×1000mm×1400mm, total weight of about 1500 Kilograms, and explosion-proof LED display.

It is applicable to belt conveyor weighing in coal mines, metering of bulk chemical raw materials in chemical plant areas, crude oil transportation weighing in oil and gas fields, and grain weighing in explosion-proof areas of grain reserve warehouses. It meets the safety weighing requirements in flammable and explosive environments, and can upload data to the monitoring center in real time to realize remote supervision and accurate material accounting.
