Xi'an Automation Instrument No.1 Factory
◎Application Description
This explosion-proof electric contact pressure gauge is designed according to GB38361.B83 and GB3836.2.B3, Meanwhile, it is manufactured according to the chart and technique document approved by the identified checking organization.
The meters can apply to measure pressure of non-crystal and non-condensing explosive mixture or non-explosive medium.
The meters could automatic control and signal alarm if they work with the electric apparatus parts with explosion-proof or other safety (for example, relay, contactor ,etc.).
