TEM magnetic sensor
It is long history to study and produce TEM magnetic sensor. Nowadays there are two kinds:

• Ground surface TEM magnetic sensor: TEM-250K (include TEM-250K (P)), TEM-70K, TEM16K, TEM7K, that applicant in geophysical exploration according to different depth.
• Borehole tri-component Magnetic sensor: JZTEM-15K, that consists two sensor: one borehole vertical HZ sensor, and the other borehole Horizontal Hy, Hx and sensor state (direction and inclination angle), which can find borehole surrounding and bottom unmoral magnetic.

Both TEM Magnetic sensors can associate with much of TEM system, Such as GDP-32 from Zonge, USA, and V8 from Phoenix Canada.

TEM 16K Magnetic sensor and result compare with GDP 32, TEM 32.

With GDP 32, there is 24 point from one section. It is 136~142 four point curve.

 
 
 
 
 
 
 
 
 
 
 
JZTEM-15K（Hz）Magnetic sensor is the special borehole tri-component sensor that used for vertical checking. There are two kinds: 1000m and 2000m depth in borehole.
1000m based on 15Mpa pressure experience and 2000m for 30Mpa, Temperature 85 Degree and sensor outside dia 38mm experience.
