TYK-18H Explosion-proof Pressure Controller
■ The controller uses a combination of piston and diaphragm type sensors
■ Can be used for compressed air containing oil mist which have no corrosion to the material of the pressure sensors
■ Can be used for oil mist gas and hydraulic oil, water-oil emulsion and good lubricating properties of neutral liquid media which have no corrosion to the material of the pressure sensors
■ The setting value of the controller is adjustable, and the adjustment range is 0.3~40MPa
■ For neutral gases containing oil mist
