What standards should the sensors used in monitoring equipment meet?
Thread Content
As the title suggests: I would like to ask everyone, what are the reference markings that can be used when installing sensors in monitoring equipment? Thank you all!
It seems that only rays and radioactive substances that are harmful to the human body require hazard bars, colored strips at a height of 5 meters, as well as hazard signs at a height of 2.4 meters. It’s a “skull”. Those that are harmless to people are unmarked.
Were the current standards such as the \"Code for Construction and Acceptance of Automated Instrumentation Projects\" followed during construction? I seek guidance from experts! ! ! Unintentional gratitude
