EGE now offers IECEx-certified signal processing units for IECEx-approved two-wire sensors. The certification facilitates exporting the intrinsically safe sensors to many countries around the world. Machine manufacturers and plant engineers can now use them in applications where they were previously barred or had to be specially certified through a tedious process.
The type IKMb 122 Ex signal processing units connect to intrinsically safe EGE two-wire sensors for hazardous gas and dust atmospheres. They feature a 22-mm wide DIN rail housing and are installed outside the hazardous area. Green, yellow, and red LEDs on the front side indicate the operating status and signal alarms, if the integrated cable breakage detection or the short-circuit monitoring is triggered. The output can be set as normally closed or normally open.
