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.
