display electrical contact pressure gauge developed to replace mechanical electrical contact pressure gauges. Based on the principle of pressure sensors and using mechanical components, it has good anti-seismic and impact resistance. It can perfectly replace the mechanical electric contact pressure gauge, and is especially suitable for equipment with pressure shock or strong vibration, such as hydraulic presses, injection molding machines, high-pressure cleaning machines, etc. The series of products also has a key to clear the zero, three kinds of display units switch and other functions. The design of the circuit focuses on stability, fully considering the actual situation of the automation site, with strong anti-dry magnetic interference, anti-surge protection, anti-reverse connection protection, etc. The product's shell and joints are all made of 304 stainless steel, beautiful appearance, sturdy and durable.
