505/7D Explosion-Proof Pressure Controller
■ The controller adopts a non-leakage piston type sensor, which can be used for compressed air containing oil mist and other oil-mist-containing gases with no corrosive effect on the pressure sensor material, and hydraulic oil, water-oil emulsion and neutral liquid media with good lubricating performance.
■ For neutral gases containing oil mist
■ The set value of the controller is adjustable, and its adjustment range is 0.3 ~ 40MPa.

Note: ① In practice, even brief pressure peaks should not exceed this value.
② The slotted seal type should be used to avoid sudden fluctuations in pressure, and if there are sudden fluctuations in pressure, a pressure shock damper should be installed on the interface of the controller.
