粉状产品的爆炸性质是众所周知的，有据可查的。 然而，这往往被忽视的一个风险是静电积聚在槽罐车。 StuvEx，谁拥有一个优秀的，世界性的声誉，其防爆系统，已经为安全接地，一个全新的电容式加油机接地系统实现了通过ATEX认证。
Safe Ground is simple to install and use and doesn’t require setting-up or calibration. It is delivered as a kit consisting of a control unit and relevant inter-lock cables and clamps. StuvEx engineers set out to make the system as simple as possible. The monitor has an easy to read visual indicator – a green light indicates that the tanker is earthed properly; while red warns that it isn’t. A relay contact is provided to prevent the conveying process from operating without the truck being correctly earthed.
In the past, capacitive earthing systems have had problems operating correctly in salt covered snow and ice. Safe Ground can over- ride the capacitive earth monitoring with a bypass switch.
安全地面有两种版本可供选择; IP 65（区域22）和EX（区域1 / 2 / 21和22）还有各种附加装置可提供额外的安全性，包括安装在筒仓入口管道上的阀门，该阀门与Safe Ground电气连接。 没有绿灯，阀门不会启动。
