D505-7DZ Dual contact pressure controllerDetailed product description：

D505/7DZ Dual Contact Pressure Controller
The controller adopts a leak free piston sensor. It can be used for compressed air containing oil mist and other non corrosive oil mist gases and hydraulic oils, water oil emulsions, and neutral liquid media with good lubrication performance for pressure sensor materials. The set value of the controller can be adjusted within a range of 0.3... 23MPa.
