Ex-amplifier installed in hazardous atmosphere
The Ex-amplifier SS 400 Ex serves to evaluate EGE flow sensors for areas with possible gas and dust explosions according to ATEX. It is classified as category 2 equipment and can be installed and operated in zones 1 or 21. Therefore, the connected flow switch can be set on site to a desired limiting value with the help of the LED chain. The relay output of the device can be operated either with type "intrinsic safety" or with type "increased safety" protection. This means that an ATEX approved device can be switched within zone 1 or 21. The switching signal can be routed from the hazardous zone to the control room outside as well. The unit is designed to meet the requirements of protection type "m" (molded), "e" (increased safety) and "i" (intrinsic safety). The sensor circuit has the protection ia and is for the connection of a ATEX-certified EGE flow sensor. The unit is supplied with 24V DC. Connecting the device to longer cables requires the housing for screw terminals GKI / GKE.
