EGE Elektronik Sensor for Explosive Productseries ST 102 S

Description

EGE Elektronik Sensor for Explosive Productseries ST 102 S is the authoritative choice for industrial facilities that prioritize both safety and operational efficiency. The “S” designation indicates the integration of a plug-in connector (typically M12), which allows for the rapid exchange or removal of the sensor without disturbing the permanent wiring of the facility. This is particularly advantageous in high-uptime chemical and pharmaceutical plants. Operating on the thermodynamic principle, the ST 102 S utilizes a solid-state probe to monitor flow velocity. Because it contains no moving parts, it eliminates the risks inherent to mechanical flow switches, such as paddle breakage, friction-induced heat, or static discharge—all of which are critical ignition hazards in explosive zones.
