505/7DZ Dual Contact 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 emulsions and neutral liquid media with good lubricating properties.

 Used for compressed air containing oil mist, hydraulic oil, water-oil emulsion and other non-corrosive effect on the pressure sensor material of the gas and lubricating properties of good neutral liquid media.

 The set value of the controller is adjustable, and its adjustment range is 0.3-23MPa.
