505/8D Pressure Controller

 The controller adopts the sensor of non-leakage piston type, which can be used for neutral gases such as compressed air containing oil mist and hydraulic oil, water-oil emulsion liquid and have good lubrication performance of the liquid medium that does not have a corrosive effect on the pressure sensor material.

 The setting value of the controller is adjustable.The range of adjustment is 0.5 to 25MPa.

 Compact structure, small size and good anti-vibration performance.
