Product Description
Brief introduction
PS131 electronic pressure switch fully upholds the design concept that to meet the worst application occasions, adopts monosilicon sensor technology and integrated housing craft, with excellent performance. 
5 dot-matrix OLED display mode shows rich menu contents and achieves the best visual effects. 3 button parameters setting to realize a good man-machine operation interface and rich functional adjustment. Independent air cavity structure effectively insulates gas-guiding side and electronic cavity so as to avoid effects of humidity. To maximum the usage of different industrial applications, high overload, anti -condensation, high precision and other demanding functions are optional accordingly.
