This standard specifies the main types, basic parameters, technical requirements, test methods, inspection rules, marking, packaging and storage of temperature transmitters. This standard applies to DDZ-III series electric unit combination meters DBW type and DZH type temperature transmitter and DC millivolt converter with electrical input (such as electrical output from thermocouples and thermal resistance elements) and simulated DC current output. Transmitters used under special working conditions should also meet relevant standard requirements.
