500/7D Explosion-proof pressure controller

■ The controller uses diaphragm sensors for neutral gases such as air and liquid media such as water, hydraulic oil, lubricating oil and light fuel.

■ The setting value of the controller is adjustable, and the adjustment range is 0 to 2.5MPa.

■ High control sensitivity
