IECEx-certified processing units for intrinsically safe EGE sensors
Published: 7 March 2019 - Sarah Mead
EGE now offers IECEx-certified signal processing units for the growing range IECEx-approved two-wire sensors. The certification greatly 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 in 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 space-saving, 22mm 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.
