HWPA1 mechanical pressure controller built-in piston (diaphragm) and precision spring connected, when the pressure changes, spring expansion and contraction occurs corresponding changes, when the pressure reaches the set point, will trigger the preset mechanical structure and send a switch signal. ● Compact structure, using DIN standard plug, wiring is extremely convenient ● Measurable pressure range (0.3 bar...350 bar) ● High repeatability, contact plating, contact capacity ● Strong overload capacity, small hysteresis, high precision ● Has normally open or normally closed output ● Suitable for general testing occasions Suitable for impact is small, the action is relatively smooth occasions, more economical ● Suitable for measuring water, oil, gas medium Applied to complete sets of equipment, machinery manufacturing, air compressor and other industries
