This standardization stipulates the product classification, technical requirements, test methods, inspection rules, marking, packaging and storage of remote pressure gauges. This standard is applicable to remote pressure gauges with the function of indicating and outputting electrical signals. This standard includes potentiometer type and differential type remote transmission chamber pressure gauges. For capacitive, electroreceptive, strain gauge, photoelectric, Hall element, diffused silicon, etc., any remote pressure gauge with the function of outputting electrical signals should also refer to the provisions of this standard for differential remote pressure gauges. Use rights. Remote pressure gauges used under special working conditions should also meet the requirements of relevant standards.
