1 summarizes
AF140-EX explosion-proof series products are designed and manufactured in strict accordance withENIEC60079-0:2017Explosive Atmospheres Part0: General Requirements for Equipment andEN IEC60079-11:2012Explosive Atmospheres Part11: Intrinsic Safety Type“ i” Protected Equipment. They have passed the inspection and obtained theexplosion proof certificate.
The transmitter is suitable for use in dangerous places withClass IIA, IIB, and IIC,Zones 0,1, and 2, explosive gas environments of groups T1-T6,orcombustible dust environments in Zones 20, 21, and 22.It is used to detectthe wind speed value of the gas (not sensitive to dust) that does not chemically react with stainless steel (1Cr18Ni9Ti) in the pipeline.
2 Basic requirements
2.1 Working environment conditions
The wind speed transmittercan work normally under the following operating conditions:
—— Atmospheric pressure:80kPa— 110kPa;
—— Operating ambient temperature:-40℃~+60℃;
—— The relative humidity of the air is not greater than 95%,(+25℃);
—— Suitable for Class IIA, IIB, IIC,Zone 0,Zone 1, Zone 2 hazardous places, T1-T6 explosive gas environment
orcombustible dust environment in Zone 20, Zone 21 and Zone 22;
—— Should be in no significant impact and vibration of the place;
—— In the environment without acid and alkali corrosive gas and strong electromagnetic field interference.
