EGE flow sensors for explosive environments permit the space-saving flow measurement on site and the comfortable setting of the limit value using separate amplifier, e.g. within a control cabinet. The measurement takes place without mechanically moving parts using a thermal measuring element. The current flow state is displayed at the amplifier using LEDs. The devices are used wherever a safe, robust and low-maintenance monitoring of flow values is required.
The sensors of the ST 100 and STS 100 product series are ATEX approved and, depending on the design, can be used in gas and dust hazardous areas. There are sensors to be used in zones 0, 1, 2 or zones 20, 21 and 22, as well as in partition walls zone 0/1. Sensors with equipment protection level EPL Ga or EPL Ga/Gb as well as EPL Da are available.
