In the materials produced and processed by chemical enterprises，There are many flammable substances present，Widely present in flammable and explosive places，according tocountryAccording to relevant regulations, it is necessary toCorrectly classify explosion hazardous areas，Reasonably select explosion-proof electrical equipment；The use of explosion-proof instrument boxes on site must comply withGB3836.1-2010Electrical Equipment for Explosive Gas Environments1Part: General Requirements "andGB3836.4-2010Electrical Equipment for Explosive Gas Environments4Part: Intrinsically Safe Type“i”》Standard; The explosion-proof mark isExquisite 4 GBIt is applicable to0District1District2District, containingIIA～IIBClass,T1～T4Places where explosive gas mixtures are present; Passed the inspection by the National Explosion proof Electrical Product Quality Inspection Center and obtained the corresponding explosion-proof certificate.

In response to on-site explosion-proof requirements, this project adopts explosion-proof instrument boxes and explosion-proof cable joints to ensure the safety of on-site instrument use. FurthermorepHThe sensor is installed with PTFE lined flange, which can extend the service life of the electrode and maintain the stability of on-site measurement data, effectively adapting to on-site working conditions.
