502/7D,502/7DK Pressure Controller
Features
■ The controller uses bellows type sensors for neutral gases such as air, gas, water vapor, and water, refrigerant, oil ,etc. liquid medium .
■ The setting value of the controller is adjustable, and the adjustment range is -0.1 to 2.5MPa.
■ Can be used for vacuum. For special requirements, the adjustment range of -0.1 to 6.3 MPa can be designed separately.
