Teletransmission sulfur hexafluoride gas density and trace moisture relay

The invention relates to a teletransmission sulfur hexafluoride gas density and trace moisture relay which can be used for sulfur hexafluoride electrical equipment. The relay comprises a shell (8), a wire holder (15) and a connector (9) are fixedly installed on the outside of the shell (8), and a base (5) is fixedly installed in the shell (8). The relay is characterized in that a bourdon tube (3) is further included, one end of the bourdon tube (3) is fixed to the base (5), the other end of the bourdon tube (3) is connected with one end of a temperature compensation piece (4), the other end of the temperature compensation piece (4) is connected with the input end of a displacement reducing mechanism (7) through a connection piece, the output end of the displacement reducing mechanism (7) is connected with a pointer (2), and additionally, a dial (1) is fixedly installed on the base (5). According to the teletransmission sulfur hexafluoride gas density and trace moisture relay, precision is high, electrical performance of a signal generator is good, contact performance of contacts is good, and meanwhile, a density and trace moisture content teletransmission function is achieved.
