DSHM-4 Transient Electromagnetic Water Detector
Transient Electromagnetic Method (TEM) is a kind of time-domain electromagnetic method , which uses ore and underground water’s conductivity and magnetoconductivity difference as main substance base, then applies non-earthing loop or earthing line source to send first pulse magnetic field to ground according to electromagnetic induction theory; Then in the gap uses coil or earthing electrode to observe second eddy field, and also study the space and time spread laws to search underground water and solve other geological problems.
1. Main Function:
1. Detecting various metal and non-metal ores, underground water, underground water-filling karsts and steep dip geological formation;
2. Searching different geothermal resources, oil-gas field census and exploration in high-resistance
3. Widely be applied in coal bed and coal goaf area and water-filling area detection;
covering area (like carbonate rock, igneous rock and frozen soil covering area), etc.
2. Main Advantages:
1. Industrial PC is as main controller and Windows as control panel, with high automatization degree;
2. The power supply working method is “Big currency small coil”, and it first realizes 200A big currency continuous square-wave power supply in the world;
3. The display is reflective LCD, the power consumption is extremely low, so we can use it in the sunshine, especially applicable in field open-air environment;
4. Use large capacity electronic disk as memory instead of hard-disk to make sure the security of equipment even in field strong vibration transportation;
5. Multiple anti-jam technology to make detect and explanation result more accurate;
6. Receiver has super low noise preamplifier; you can choose proper stacking times at random to guarantee measurement accuracy and wide dynamic;
7. Advanced interpretation software system: include half-space interpretation software system for ground work and full-space interpretation software system for underground work (coal mine tunnel, tunnel, military affairs etc.)
3. Technical Specification:
Receiver:
1.Whole domain data acquisition, sampling rate is changeable: 1μs, 4μs, 16μs
2.16 bits, 1M/S, A/D converter adds real time floating-point amplify, dynamic range: 140dB
3. Max. sampling delay time range: 64ms
4. Resolution: 0.1μV
5. Memory: 256M
6. Hard disk: 40G
7. Interface: USB, parallel port, serial port, network card
8. Display: Colorful high brightness TFT 800*600 lattice
Transmitter:
1. Currency intensity (A): 25, 50, 100, 200
2. Currency pulse width (ms):10, 20, 40
3. Weight (kg): 2
