英文摘要An industrial process device with a wireless function is provided. An internal circuit of the device is protected by an external metal housing. The housing of the device is made of a metal material having the electromagnetic shielding function and is grounded. The internal circuit adopts protection measures, such as differential-mode noise suppression, common-mode noise suppression, overvoltage and overcurrent protection and the like, so that the influence of electromagnetic interference in a factory on a circuit can be greatly reduced; and meanwhile, the metal housing can also shield the interference generated by the internal circuit in the metal housing, thereby not causing influence to the environment outside environment. The structure of the housing is designed in an explosion-suppression manner; the structure parameters accord with relevant provisions in national explosion-proof standard GB3836.2-2010 (equipment protected by explosion-proof housings "d " in explosive atmospheres), and the wireless gateway device is allowed to operate safely in an industrial environment having inflammable gases.
