1. Product introduction
This series of products using rubber/metal 316L diaphragm sensor components,ordinary type suit for gas, liquid and steam which has no corrosion effect and achieve automatic control,Controller set point is adjustable,The range is -10~0~10MPa,the adjusting range is 15%~ 95%. The quantity of this switch almost is 1Kg. The mark of anti-explosion is ExedllCT6 and suit for gas, liquid, or steam and medium IIA IIB IIC T1~T6 explosive mixture which has corrosion effect and achieve automatic control. If you adopt window type, please give instructions before you buy it, the window type number is
KSVC dead zone cannot be adjustable, and KSVA dead zone can be adjustable series.
Single pole double throw switch process:
Wiring terminal C-NO: the raise of pressure till changeable value ON;
Wiring terminal C-NC:the raise of pressure till changeable value OFF.
