Powered by dry battery UM-5,it mainly is composed of source coil,transmitting circuit,magnetic-inductive materials,and stainless steel shell.Fitted in a pig,the emitter sends out pulse signals of low frequency in operation.It has the advantages of long working time,convenient battery installation,signal stability,shock resistance,and high pressure resistance.

Continuous time: 100h-200h;

Pressure resistance:0-10Mpa
