Page 4: Application
1 Application 1 Application The pressure sensor DG smart is a relative and differential pressure sensor which monitors the MIN/MAX and/or differ- ential pressure for gas, air, flue gas or other non-aggressive gases. DG smart meets the current requirements of DIN EN 1854:2022 (Class A and C) and international stand- ards which require the safety function of MAX/MIN monitor- ing and shut-down. -
Page 5: Application Examples
2 Application examples 2 Application examples 2 .2 Low and high gas pressure protection at the gas inlet section 2 . 1 Air line with MIN, MAX pressure monitoring PZL/ PZL/ VSBV If the pressure is either too high or too low (PZL/PZH), the gas pressure sensor prevents the system starting or trig- gers a safety shut-down. -
