The evaluation center of the third generation is designed as a separate device intended for mounting on the surface. It serves to power 16 to 32 gas sensors connected via RS485 and up to 8 gas sensors connected via a 4-20 mA current loop. For sensors, it evaluates gas leakage in four levels. The statuses of all sensors are indicated on the control panel using the LCD display. The control panel can be equipped with up to 10 freely configurable relays, an output for optical and acoustic signaling, a USB port and RS485 for connection to a superior system (PLC, PC with visualization).
