Description

The shock-resistant electric contact pressure gauge has excellent characteristics such as resistance to medium pulsation and impact load, resistance to environmental vibration, etc., and is suitable for measuring the pressure of gases, liquids or steam that are not corrosive to copper and copper alloys. The instrument is equipped with upper and lower limit two-position switch type contact devices, which send out a signal or turn on and off the control circuit when the pressure reaches the set value for automatic control or signalling of the operating system. Its anti-vibration structure can effectively suppress the jitter and impact of the pointer, protect the contacts, make the indicator clear, the electrical signal switching is reliable, and the work is stable.
Application of shock-resistant electric contact pressure gauge: Widely used in industrial production processes such as machinery, chemical industry, petroleum, metallurgy, and electric power.
Environmental conditions for use: Operating temperature: -25℃~55℃
Upper limit of working pressure: not more than 2/3 of the upper limit of the instrument
The vibration frequency of the working environment is not more than 25Hz, and the amplitude is not more than 0.5mm
