Beschreibung
Zusammenfassung:	The utility model discloses a full-automatic SF6 density relay calibrator, which comprises a main control module, a pressure transmitting module, a three-path constant current acquisition module, an air pump module, a relay temperature acquisition module and a power supply conversion module, the output end of the power supply conversion module is electrically connected with the input ends of the main control module, the three-path constant current acquisition module and the relay temperature acquisition module, the output end of the pressure transmitting module is electrically connected with the input end of the main control module, and the output end of the main control module is electrically connected with the input end of the air pump module. The device has the advantages of stable performance, small environmental influence, sensitive reaction, low production cost and low possibility of being influenced by other gases; meanwhile, multi-point distributed installation and use are facilitated, and leakage equ
