Pre-suction Pump Block for the sampling from the EX ZONE II

The gas warning Unit Analys 2000 and 2016net with the sector valve block and the presuction pump block is a modular developed stationary gas warning system. The measured gas will be lighting by a pump and supplied via the solenoid valves, gas inlet pipes fed to the gas sensor. To obtain for the shortest possible cycle time, will be every position of the suction process before sample drawing pre sucked with a second pump. A valve block switches cyclic from the pre suck to the sample drawing and actuates the calibration.
