Information such as the explosion protection rating of WIKAI pressure gauges – please provide an interpretation
Thread Content
The WIKAI pressure gauge is used for measuring ethylene, with a range of 0-50 Mpa. Its explosion protection rating is as follows: PTB 06 ATEX 2018 X.1.suppl. Ex 1/2G. 2G Ex d ia IIC T6. The questions are as follows: 1. I don’t understand what PTB 06, X.1.suppl., and 1/2G mean. 2. Does Ex d ia refer to explosion-proof and intrinsically safe types? I hope the experts on this forum can help me; I’m extremely grateful
1. I don’t understand what PTB 06, X.1.suppl., and 1/2G mean. Answer: I’m not entirely sure either, but it seems to refer to the certification body and the certification standards; explosion protection certifications are generally IEC and ATEX, though I’m not aware of the exact wording used. Looking forward to the expert’s answer! 2. Does Ex d ia mean explosion-proof and intrinsically safe? Ex d ia refers to dual certification for explosion-proof and intrinsically safe properties, meaning it meets both explosion-proof standards and intrinsically safe standards.
It’s a broken pressure gauge – it’s not an electrical device; what does Intrinsic Safety and explosion protection have to do with it? . .
No, this is a pressure transmitter – it’s not purely mechanical; it involves some electricity as well
Question 1: They should be the tag number, explosion protection rating, and electrical interface dimensions respectively. Question 2 is the same as that on the second floor
. PTB 06: PTB is a German certification body; 06 is unclear whether it represents the level of certification or a classification code； ATEX 2018 X.1.suppl: ATEX is the EU explosion protection certification standard; what follows should be the version and number ； Ex: Explosion protection mark 1/2G. 2G: Equipment classification, similar to the classification of mining and non-mining equipment in national standards. Category 1 roughly corresponds to Zone 0, and Category 2 roughly corresponds to Zone 1. G denotes gas, vapor/fog; dust is denoted by D ； Ex: Explosion-proof certification mark d: Flameproof ； ia: Intrinsic safety; IIC: Environmental category, with hydrogen being the environmentally representative gas for IIC ； T6: The highest surface temperature category, with a maximum allowable surface temperature of 85°C for T6.
What was said upstairs is basically correct – this damn pressure transmitter is explosion-proof, combining isolation explosion protection with intrinsically safe explosion protection; some of its components use intrinsically safe technology while others rely on isolation explosion protection. No need to say more
