The safe choice for a chemical plant
A chemical plant in Zhejiang makes flammable solvents. All their weighing equipment needed explosion protection. We provided an intrinsically safe explosion-proof load cell. Marking: Ex ia IIC T6 Ga. The sensor uses 304 stainless steel. The circuit is energy-limited. Max short-circuit current is 30mA. Max open-circuit voltage is 8V. Even with an internal fault, it will not create a spark. The customer passed their safety assessment and ordered 20 more sets. Safety certification is not just for show.

Full solution with all certificates
We provide a complete explosion-proof weighing solution: explosion-proof load cell, Ex e junction box, Ex d/Ex ib indicator, and safety barrier. All products have Ex certificates and CCC certification. Need dust explosion protection? We have Ex tD A21 IP65 T80℃ for aluminum-magnesium dust or flour environments. A common question: "Can your explosion-proof load cell be used in Zone 0?" The Ex ia version is suitable for Zone 0. Yixing Silvanus Electric Manufacture Co., Ltd. has been making certified sensors since 2007. Choosing us means you do not have to piece together components. We handle everything and help with acceptance.
