Product Description

Metal detector Electromagnetic instrument WTEM Transient Electromagnetic Survey System

 

Product Description

Transient electromagnetic detection is one of the main means of geophysical detection. It stimulates underground targets by transmitting electromagnetic waves underground, receives the secondary field generated by it, and determines the physical parameters of the measured target. Transient electromagnetic measurement uses an ungrounded coil (or loop) to transmit a transient magnetic field underground. Usually, a square current wave is supplied to the transmitting coil to generate a stable magnetic field distribution underground. When the square current wave is turned off, the earth medium will generate eddy currents, the size of which depends on the conductivity of the earth medium.

Main Features & Founction

Observe the secondary field after power failure, and observe in the near area, reduce the influence of side measurement, and enhance the electrical resolution ability;
The same point combination (overlapping loop, central loop) can be used for observation, which has the tightest coupling with the detection target, and the abnormal response obtained is strong, the shape is simple, and the layering ability is strong;
It has the ability to penetrate low-resistance coverage and has a large detection depth;
Because of measuring the magnetic field, it is less affected by static displacement;
Through multiple pulse excitations, repeated observation and superposition of response signals and the application of multiple coverage technology in the space domain, the signal-to-noise ratio and observation accuracy are improved;
Profile measurement and depth measurement are completed at the same time, providing more useful information and reducing multiple solutions.
The ungrounded loop device is used, which is suitable for working in various geographical environments.
Low noise, low power consumption, small size and light weight.
Human-machine interface, simple and convenient operation, and strong operability.
