This pressure gauge is suitable for measuring the pressure of non-crystalline, non-solidified explosive mixtures or non-explosive media in places with explosion hazards. It is used in conjunction with electrical devices (such as relays and contactors) that have corresponding explosion-proof function or have taken corresponding safety measures. It can realize the purpose of automatic control and sending alarms in the controlled system.
This pressure gauge has measurement and control functions. It can be arbitrarily set the upper or lower pressure limits, and the indication is stable and reliable. It is widely used in petroleum, chemical industry, power station, metallurgy, water supply and other industrial and electromechanical equipments.
